Has anyone seen anything like this wear on their R9/R9S?

I am seeing wear on the under/out side of the rails, inside of the rails, below the barrel lug, and on the front/top end of the frame. It started with loss of the anodized coating. I thought this was normal. After the last time out shooting (today), I disassembled/cleaned and noticed quite a bit of wear into the aluminum frame. This was new and quite alarming to me - I won't shoot the gun again and will send it in for a look-over.
Some of the details on my use: I've had the R9S since May 2004. I have ~600 rounds through it. The first ~50 rounds were silver tips and the remaining have been 115gr gold dots - std pressure. I have taken the gun apart after ever range session and cleaned/lubricated. I shoot between 13 and 50 rounds per time. I lube the heck out of it per the pics that Eric sent Duane and Chris posted on the FAQ site. I changed the spring at ~300 rounds and then again at ~550 rounds. I saw some removal of the anodized coating right from the start so I figured this was normal. Eric had told me that this gun was in the first batch to get the new darkened anodized finish - don't know if there is any relationship here…
I've carried this gun in my pocket for over a year now and can count it's daily absence from my person on under two hands.. Putting it in the box to send in feels like taking off a piece of my body. Love this gun and my Hedley back pocket holster (in my front/right)… but then I know you folks feel the same.
Any insight is appreciated..

Looks like you gotta send it back, something is wearing outa spec.
-
Brian - thx for excellent picsd and a good description. I am to be honest somewhat mistified. First look of course one thinks - ''must have run dry'' but no - you seem to have been very methodical and careful in your maintainance.
True - it must go back and hopefully the folks will establish some ideas on the ''why'' of this. With the precision fit of parts and lube this should not in theory be able to happen - certainly not in a gun so young - in thruput terms.
I can well imagine the reluctance to part with it - but seems only way. Mine is not daily carry - just BUG and sometimes primary but heck - even with mine I'd be sorry to not have it here.
I wonder - any ''witness'' marks inside slide - anything that matches up with that frame wear? Probably not but just wondering.
Do give any feedback possible later - and sorry not to be of much use with suggestions.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To add - just looked at pics again - is that hole for the pin looking a tad ovoid? Hard to be sure from pics but - has pin developed some slop?
-
An unlucky R9 day. Zamboni has a cracked slide on another thread, and Brian all of the sudden gets unusual wear at the 600 round mark. Keep us informed what the Rohrbaugh guys have decided caused these problems. Sorry gentlemen!

To the first, I did look at the inside of the slide and the barrel lug and see no indication of "witness" marks, but then I'm not surprised as they are steel vs aluminum - I'm sure that is what you were thinking.
To the second, the pics do make the hole look a bit oval but this is not the case. The pin fits very tightly.
Thanks for the comments
-
Hmmm - gremlins coming out of the woodwork!
Well - hopefully these issues will be resolved and - more useful - add to the database of experience for the Bros R.
I am sure we are still going to see occasional hiccups - part perhaps of the evolution of the pup. This is one thorobred that is still growing the last teeth.! ;)
Probably inevitable.
-
Brian,
Yes, I have the same wear markings on my R9S. I also clean & lube (per Eric's recommendations) after each & every trip to the range. (i wonder if my cracked slide is related to the frame wear...?)
I'm going to miss my R9S while it's being worked on; will have to carry my GLOCK 30 instead (great piece, though quite a bit larger than the Rohrbaugh.)
Thanks.
Zamboni
Yeah, I'd like to have the 30. I have a 26 that I will have to carry for a bit. Never carried it consistantly - nor any gun for that matter, until the Rohrbaugh. It fits me perfectly.
-
Mine coming soon, this post has me worried, is it an isolated case? I couldnt live with a gun that has weak points. Am anxious to hear more about this situation.
-
I think factory feedback is what we need so as and when there is further info - hopefully it'll be seen here.
-
Datan & Zamboni how close are your serial #'s? This could be a bad run of materials or machining out of spec. ??? :-/ :'(
-
It would be nice if others who have put a few boxes through their R9s took a close look to see if there has been any anodization loss on their guns at the wear sites of Brian's R9.
If I'm reading Brian's post corectly the wear at these areas, that are now into the frame metal, started with slight Anodization loss.
Zamboni says he has seen Anodization wear also - don't know if he means at the exact same areas as Brian.
It would seem that some very slight anodization rub off at slide contact sites would be normal - or is it? Think all would appreciate some feedback and comparisons.
-
I will have to strip both mine down to analyze - my #1 in fact has had the greater ammo thruput tho only a tad over 300 - the second one I have got broke in at 100 or so rounds and left it there - approx 50 for starters and then the odd mag' now and again.
I dry fire quite bit too.... which of course has no effect in this regard.
Once I have looked I'll give any relevant feedback.

Well, I have a custom serial number as you can see. What I know is that mine was in the first batch to receive the dark anodized finish. I'd call this an early gun. I've had the gun in my possession since May 13th, 2004. I paid the money for the gun in Sept 2003 and Eric told me it was in production in October 2003.
Zamboni's is in the 500 range so these guns were probably manufactured at different times.
-
I'm having some wear in the finish after 30 rounds -- not really any more than my 1911 had on it's Al frame after it broke in -- if this isn't normal, though, I'd like to know.

I have the same wear marks on my R9. In fact, I had to send mine back for some FTE's and FTF's problems that I had. I even listed it in my letter of discrepancies when I sent it back. I haven't had a chance to shoot it since I've gotten it back but, they didn't mention or say anything about the wear marks when they contacted me about the problems they found. This led me to believe that the marks were just normal wear. My pistol is a very early model with less than 300 rounds through it.
-
I have the same wear marks on my R9.
On your R9, are the wear marks just removal of the finish or do you have areas that are worn into the aluminum? If you refer to the second pic that I posted and see the worn lines between the rails (focus on the top line specifically), you can see (kind of) that it is dug into the aluminum and something has actually gouged and pushed some aluminum back towards the rear/mag well...
-
Guys - I have just stripped mine down but have to take some pics. I already have some thoughts/observations. I'll post again soon as I can.
-
Ok - taken some pics - apolagies tho because a bit rushed and lighting not really quite showing as much detail as I'd like. Suffice to say tho - here we see similar pattern tho, not much displacement - mostly ''rub'' type appearance - no real burrs to be felt.
The light color frame is of course my #1, with approx 300 thru. The gray frame is #2 and that has only about 100 approx thru it. I reckon this effect will show very early possibly.
The first two pics are attempts to show the main wear area, similar to Datan's pics of that area.
The third is a side view, taken because I want to raise a point. I am adding more commentary after pics .....

(http://www.acbsystems.com/boards/thr/shoot5/r9/r9-frames-1090-s.jpg)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
OK now, here is what I am thinking. First off steel/aluminum - no contest re hardness so even with lube, enough pressure can and will lead to some change in frame surface. I reckon that any rub at all - slightest - will perforce leave some marking on anodizing .... even slightly removing same. That tho is just miniscule rubbing.
Now, looking at what leads to this main wear appearance, I am of opinion - for now at least - that this is caused by the under side of chamber area - either side of lug. During firing cycle, barrel unlocks as soon as slide proceeds rearwards .... and then as slide returns it again locks up. Once unlocking then I see the probablility of some slight downward movement and I think it is the slight ''impact'' rub from this that is causing the wear.
Because of this I do not see the wear as overly prejudicial and it will possibly be self limiting over time.
I placed that third pic to provoke thought over the prime required integrity - which is slide on rails. I can see no wear on my rails at all - the most is a small anodic ''scuff'' on the darker frame rail in view.
Now if I saw wear on the rails I would be concerned - but here we have tight tolerances, and proper lube will prevent any problem because we have linear sliding motion and little else.
The barrel unlocking produces a different stress - not a stress that will lead to any failure - just a stress resulting in a slight ''slamming'' of chamber base against frame twice each cycle, with perhaps a slight ''shuffle'' too. In fact unlocking may be more to blame - or locking may be so - hard to tell - let's assume both have equal effect for now.
Do you see where I am coming from here? I am not trying to say it is a desirable trait to see per se - but looking at the mechanics, stresses, materials and results - do not see this as overtly prejudicial.
I shall still be interested to know the R Bros take - I am also interested to see what Eric might say when looking at his early gun which has had IIRC over 5k rounds thru it. Is that showing same? Is it any worse?
I'll leave this here for now and think further but this is where I am at right now. Open to any input.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
BTW meant say - sorry about some crud showing!! I did a very quick wipe over to get rid of surplus lube but did not continue to produce a pristeen state! Too much to do this evening.
.
-
Chris,
Your pics are fine-crud and all.. ;)
I do know that there is a difference between wear of "finish" and the material of the frame / slide..
I personally have not seen anything more than natural finish wear,but I have not shot a K worth of of rounds yet.. ;)
If there is a problem-Rohrbaugh will take care of it and let US know, I am sure..
-
Datan,
My pistol looks like your pics; it is definitely worn into the aluminum.
R9SCarry,
I understand what you are saying.... however, with the quality and detail that goes into these pistols, you would think that they would have just milled off just a little more in that area just so there wouldn't be any cosmetic issues. I am also sure that there isn't any problems with the wear but when you disassemble it and see the gouging in the frame it doesn't boast a whole lot of confidence in the quality and quite frankly it suggest that something is out of spec. It especially isn't desirable when or if someone wants to try to resell it.
-
I agree wldavis, shortly I will be a rohrbaugh owner too, Like you stated, a gun with so much wear will be hard to resell. I remember hearing carried a lot, shot a little. Guess this statement holds true. I just am feeling a little uneasy now,as I would not be happy with a pistol that would be so wear sensitive as to keep me from shooting it too much.
-
Thouhts on the frame wear
It seems to me,
As a machine is used, evidence of wear will occur. If there are different materials used in the construction of this machine, the wear will be more pronounced on the softer of the two materials.
The Anodize finish will be the first to show wear. Anodize is no different from a Blue finish in that respect.
If the slide and frame were both of a like material, there will be shiny spots [ideally] or rough spots [galling, not good]
Shiny spots[from above]
These are high areas, or areas where forces change direction. The Slide , in it's rearward travel, has to have changes in pressure against the rails, due to the barrel breaking contact with the slide.
I'm not too good at putting all this into words, but I hope it will provoke some more realistic thoughts on this discussion. We should not expect to shoot this pistol and not have evidence of it.
Keeping the pistol clean & lubed is the best protection against premature wear
This IS NOT aimed at anyone in particular.
I'm in full agreement with R9sCarry
-
RJ well said. It is not the normal wear that concerns me, it is the galling from the previous pictures. Poster said he properly lubed his gun, his gun had imo excessive galling, thats my main concern. I am not a metal guy, so its just my opinion. thanks
-
>>I have two R9s...lube generously as per factory specs, etc.
The first one I got was used with ~500 rounds through it, and I noticed the same wear on it the first time I had it apart some 50 shots later.
The second gun arrived new in March of this year...and I noticed those same wear marks on it within 100 shots.
At this point I am not too concerned about the guns, although I watch this thread with interest. I have all the confidence in the world in the R-bros, and would not hesitate to purchase again at this stage. I think we need to watch that we don't start up any unnecessary group alarm, and we need to get some feedback from Karl and Eric. However...if anyone wants to "unload" their R9s at a bargain price - I'm buying...!!..TW<<
-
Just to re-state a point I made ........ I don't think this wear area we are discussing is going to be prevented by lube, however generous. It is in a different category from the slide rails.
It is a result of ''upsetting'' from barrel ''shuffle'' during unlock/lock IMO. The design and tolerancing being so tight does mean that this is one area above all which can be prone to wear showing - but as I mentioned, I think this will be self-limiting.
Sure (perhaps) that area could be machined to give more clearance which might negate the effect .... not sure..... but as TW has said this starts early in the gun's useage and as things are, is I reckon inevitable. Because of the hardness differential it is rather obvious on the aluminum but I'd not be surprised if Erics #1 (5,000 rounds plus) shows similar but no worse despite the huge thruput - as I said - it could be self limiting once the gun is ''bedded in''.
I think it is very important to separate this issue from slide rails.
-
Great observations/thoughts Chris/RJ/All.
Think we can say that wear in these locations is "normal".. to the extent mine is worn compared to others is in question - will be very interested to hear Rohrbaugh's take. Chris, your dark frame doesn't look too dissimilar to mine - thx for the great pics (as usual).
Will keep everyone posted.
-
I just got off the phone with Karl. After describing what I'm seeing, he told me "I know exactly what you are talking about". He said this happens with the early guns. I was told to send it in and that they'd "update" the gun for me. I don't know exactly what "update" means. I'm told I'll get the exact same gun back - they are not going to swap out the frame. Karl sounded very busy so I didn't drill him further on exactly what will be done. They are aware of this phenomenon, however, and have a "fix". Wonder if they are going to mill the curved area down or something... I will try to get more info and share..
Brian
-
>>Chris - In your second pic...the one looking straight down from above it appears that there are some metal flakes grouped together in the cylindrical depression of your dark frame gun. Is this so...?...and if it is - where do you think they originated...?...TW<<
-
Indeed TW - I had forgotten to take a closer look and glad you asked - as I mentioned when I posted the pics, both guns were rather casually cleaned to wipe off grease - but I was aware there was crud remaining - just me being too lazy!
I just checked again having previously re-assembled quickly and yes, there were a coupla small flakes, the rest being grease residue. I guess not overly surprising as what came off the frame had to have gone somewhere!!
Glad you brought that up or I would not have checked real close.
-
Has anyone received official commentary on this frame wear from the factory personnel?
It seems like that amount of abrasion is worthy of some consternation and comment from 'above'.
Has anyone gotten word from Eric on this?
-
shyhook, I agree, to me this is a serious issue.
-
I have had contact with Eric but - he would ask that folks wait for an analysis to be made which should be soon. No point in going off at half cock.
I have theorized a bit so far but that's all it is - and when there is definitive info for release it will be quoted as direct from Eric and/or Karl. I or one of us will post the full skinny when received but not until then.
Patience folks. :)
-
Thank you rs9carry
-
>>Chris...
I have a question for you...again going back to that second pic of yours - where I pointed out the metal shavings collected in that cup-like structure in the bottom of the frame. Are we tracking now? OK...my question is this - what is the purpose/function of that shallow "cup" in the frame - right in front of mag well...?? I think I know but I would like to hear it from you, or anyone for that matter.
The reason I ask about that cup has to do with what I saw last night when I cleaned and lubed both my R9s. It appeared in my older gun that there was a lot of wear along the wall of the cup nearest mag well...the top of the wall at that point being worn down and rounded. From looking at your pictures it looks like your gun may be in the early stages of doing this - do you know what I am talking about? I compared this to the same area on my newer gun...and I could see a clean straight wall on that one, although it almost looks like the wall on that side was stepped to begin with. There is just the beginnings of wear starting that area on the newer gun. I regret I was not in a position to photograph what I am seeing - was late and I wanted to get to bed.
Thoughts, please...?...TW<<
-
I've been following this thread as my R9s is due in any day now. The only other alloy frame gun I own is a Sig P239 in .40 S&W. After 1,000 rounds the frame looks like this:
(http://i21.photobucket.com/albums/b271/sluggo24/SigP239Rails_7.jpg)
There is evidence of "polishing" thru the anodize coating, but no flaking or other pickup on the front of the rails @ dust cover, or back at the receiver end. (The steel hammer shows more polishing than the aluminum frame.)
I've used only EEZOX on this gun since day one, but have recently switched to Brian Enos's Slide Glide for those rubbing surfaces.
BTW: The Sig has been 100% reliable for me. Just a little too big for pocket carry and I find concealed carry holsters too uncomfortable in warm weather.
-
TW - I am in and out a lot today but will strip both guns again later on and get Mk I eyeball into play and report back for you, plus some deliberation! :)

>>Deliberations...? That mean I've been bad and you are going to set me straight...?? Should I start groveling now...??...**TW scratches head**...
-
Haha - TW you just beat me too it - am gonna try and ''splain'' all this! Grovel all you like BTW - love it!! ;D
OK this may take a few minutes to write up so - watch this space, back soon ...................... :P :P
-
TW - given time and some of that on CAD (:) )I could show some aspects graphically. But for now I will attempt (operative word) to do this thru description.
That ''cup'' in the frame is actually receiving the barrel lug base protrusion at fully unlocked - at which point it actually could prevent feed ramp from being any further back than level, with the mag' well. It is tho not designed to take that much of a whack!
Coincident with that at unlock is the actual and theoretically main limiting factor - the pin, in the lug slot. That should prevent the barrel setting back any more on it's own so - the ''cup'' is actually a clearance device shall we say.
Now, also at unlock the barreland lug is at its lowest point, having dropped, thus the contact with the wear areas we have seen by the exterior of chamber profile. I say contact - in fact from a design POV I expect with the incredibly tight tolerances in this gun, we have a theoretical ''barest kiss''.
However, if we consider the extreme violence of the event (firing) during a full cycle - it seems very likely to me that a two or three thou over travel downwards, and maybe a thou or so to rear (heck, this is a demanding gun to design!) - and we can see the slight attrition to the surfaces and thus a very small flake or two of displaced aluminum.
I still feel this is self limiting and I guess if tolerances were sloppy as heck, it might not even happen. Now remember folks - this is me theorizing and not Eric taking. That will come later when we have full answers!!
Looking at the whole cycle and so recapping a bit (heck - wish I could animate a Flash file like the one on a 1911) ..... I can ''see'' it clearly but description in words is a bugger!
At instant of slide beginning rearward travel as round fires and pressures begin to back off from peak, we have the barrel moving rearward by approx 1/4", as recoil assembly is being compressed by slide - (exerting as it does said rearward bias against barrel lug) - at which point the lug slot allows it to drop, and there it stays while slide goes all ways to rear.
Slide progresses then forward, stripping a new round - which is fed into the lowered barrel and chambered, assisted by the feed ramp. The completion of the auto load is aquisition of full battery and as slide moves further forward, and recoil assembly is (relatively) relaxing, we see the bolt face area impinge on the round's base to complete the action. The last 1/4" or so as round goes into battery and slide closes, is when the lug slot then rides the pin to lift chamber area (barrel rear if you like) once more and go into full lock-up.
Phew - if you understood any of that it's a miracle. How useful an animation would be!! Just don't have the time.
See if this fits in TW with any thoughts you or others may have had. I am as ever verbose and rambling - but this is not that easy to describe so as to make it foolproof to understand!
;D
-
Wow Dr. Chris - very complete answer. I know I learned more than I thought I would before I started the read. Reminds me of my graduate school economics classes when I had to read the stuff several times to understand it.
Now if we had the animation .......
-
Dave - I am seriously keen to try and do an animation but - it is a deceptive amount of work. I would not be surprised to spend a full week on such a project - to make it halfways adequate.
Maybe - sometime! :P

Good job, R(SCarry. Now if the rest of the explanation (wearing) comes in that clearly, we will all know exactly what's happenin'.
Thanks.

R9SCarry
No, it goes like this, " How does that pistol work?"
"After a loaded magazine is fully inserted in the mag well, you pull the slide fully to the rear and ............'
What's a fully loaded Magazine?" .........and "what's A Mag well?"
:D

Not funny, Hedley.
Are you 'makin fun' of the questioning?
-
My R9S is expected within days. Naturally, it's somewhat alarming to hear reports about slide wear. UPDATE: frame wear, not slide wear. Sorry.
My impression is that wear was noticed on some of the early pistols. It is not unreasonable to think the fix has been applied to current production models.
Meanwhile, based on all reports, I have absolute faith that any and all problems will be corrected by Rohrbaugh.
I hope Karl will add a Technical Support section on the factory web site, where we can read the official reports direct from the factory.
-
Michigunner - just to mention - not SLIDE wear in fact - this is the wear on the frame! There has been one case I believe where a slide has shown a crack, which is a different situation entirely. :)
-
Whoops! Thanks, Chris.
I meant to say frame wear.

-
I have an update - I will link to the voicemail that Karl left me regarding the details/status of the gun. I must say that the service is outstanding. They received the gun in the AM and had it modified/fixed within ~4 hrs and Karl called me with an update that same day.
Here is a link to the .MP3 (I apologize for the poor quality): http://members.cox.net/datan42/KR.mp3
If for some reason you can't hear the message, Karl refers to the contour of the barrel being changed and that the wear seen is not an issue. They refinished the frame after taking off the burrs. I will post the "after" pictures as soon as I get the gun back.

That is an example of first class service.

Whew! (Big sigh of relief)
One of the few suspects was the contour of the bbl which contacts the frame. I am really pleased at Eric & Co's rapid response and hope that is that.
Mine's due sometime in Sept....or Nov.... or......
-
Thx for the feedback Brian - in fact the MP3 played quite well enough to hear. I think overall as I see it, this pretty much supports some of my thinking.
-
Audio came thru great for me...
Sounds like Great service to me.. :)
-
Thanks Brian for putting on the audio - it was nice to hear the reasons right from Karl. I'm sure it made many of us feel better - it did me. Would be interesting to see what they did to the barrel contour.
-
Busy week so it took me some time to break the gun down and snap a few pics. Here is what they did: (1) rounded the rear edge of the barrel, (2) changed the guide rod, (3) changed the extractor spring, (4) changed the barrel pin. Don't think items 2 - 4 were needed (I had changed the barrel pin previously to the new harder version) but were nice. Item #1 was the main work. The newer guide rod looks more polished and the has a beveled front edge. Here are the relevant pics:
The barrel post "update" - notice the back edge of the barrel - it is rounded.
(http://members.cox.net/datan42/R9Barrel2a.jpg)
The barrel pre "update" (old pic) - notice the sharp edge at the back of the barrel.

They knocked off the burrs:

Happy to have the gun back in my pocket! The factory again stated that this wear was normal.. actually, the invoice stated "wear is excellent" :).
Brian
-
WOW! Top Notch service!!!!!! ;)
-
Brian,
Top notch before and after pics - thanks from all of us.

I'm glad Datan posted such clear photos of his R9 "after rework". I reported yesterday on my second range session (157 rounds cumulative total). My frame is wearing exactly like Datan's in the area below the rails, though mine shows no evidence of contact in that pocket.
My gun is serial #R360 and was delivered less than a month ago. It has the latest recoil assy with chamfer at front, radius on rear of barrel chamber, etc. I have to admit that I treated those heavy wear areas with Brownell's Action Magic II before Super Lubing and reassembling. Probably won't make any difference, but I feel better.
BTW: I've found an easy way to get the barrel pin back in during reassembly. I insert my Stop Stick up to the same mark as I use for disassembly. Then I ease the slide back a bit with a finger over the end of the barrel's muzzle until the assembly holes line up. With my third hand I can then drop the pin in easily. ;D Actually, I have the gun positioned so the pin drops in vertically & put the pin in the slide hole, then wiggle the slide back a little.
It's easier done than explained.

Just a quick message to say that I experienced frame-wear very similar to this after the 100 rounds of 124GR Gold Dot I put through the weapon for firearms qualification. To my eye the wear is closer to what Datan experienced that to what R9SCarry experienced (i.e. looks worse). But I am witholding judgement for the time being.

That is normal with the tight fit and aluminum against steel. I think about everyone has that after awhile. It seems to be self limiting. After a period of time it will set in and not wear anymore - at least that what most experiences.
