Title: Suppressor?
Post by: ucfjoe on May 28, 2009, 03:04:59 PM
Long time owner (since late 2004). I thought I had registered on this site before but I can't find my old login.

Anyways to my question and I'm surprised no one has asked it before, perhaps the answer is too obvious?

Can a suppressor be put on a R9? More importantly, would it cycle properly? I have a feeling it wouldn't and want to ask before I go through the trouble of trying to get a threaded barrel made.

Also, before anyone states it, I know it wouldn't be practical and might look a little funny in my pocket but I don't care.

Welcome back!  

Can't help you much other than to say I just would use a pillow?

Cheeper, don't need a federal stamp, threaded barrel, or new holster and you could strap in to your back when carrying?  ;D

too bad feathers cause a r9 to misfeed faster than my 147 gr target rounds...

Son of a gun, didn't think of that but I know your right!

How about a synthetic pillow?

I think (that gets me in trouble) that the barrel would have to be custom made.  I'm with you on the coolness factor!  If it happens please post pics, it would be a first.

IMO -- Suppressor for R9 = (1) lots of re-engineering; (2) lots of paperwork; and (3) assuming completion of number (1) but failure to complete number (2), lots of new "acquaintances."   ;)

That sounds like wise counsel to me.

the paperwork part is not an issue.
what do you mean by re-engineering? more than getting a threaded barrel made? it works fine on full size pistol so is this a physics issue due to thhe size of all pocket guns or just the r9?
 note I have searched and found no info (good or bad) about suppressors and pocket guns including the keltecs which is suprising to me.

Thanks tracker, I'm glad someone agrees with me and my pillow idea.

ha. ill draft a letter to cor bon and see if they would be interested.  maybe even a reloading kit for it?

While your at it why not ask about a scope or C more sight install?
Let's really trick it out!

Hey, I met Q at a BMW auto show in Las Vegas.  He was a guest speaker, very funny guy really.  May he rest in peace.

One of the James Bond girls was there also, can't remember her name but remember what she looked like!

Yes he would approve.

ucfjoe:

First of all, I forgot to welcome you back. My apologies.

As for that re-engineering part, I'm just a lowly lawyer (one of the good kind who believes in the Second Amendment), so I'll have to leave that question to the engineers and physicists among us. It's just that after watching Corey work so hard to solve the mysteries of porting dynamics for the R9, I have about reached the conclusion that this little pocket rocket is so finely tuned it doesn't take much in the way of modification to throw it out of "kilter."
Title: where are all the engineers???
Post by: ucfjoe on May 29, 2009, 03:53:10 PM
thanks Richard

I was doubtful that it would work and was hoping that someone could tell me it would work. I guess i'll try first on my p-11 and if that is successful than maybe i'll venture back to trying it on the r9.

You can mount a suppressor on anything.  The question is, would it cycle?  And in the case of a Rohrbaugh, would it overstress the gun?

Suppressors work great on fixed-barrel guns, where there is no cycling issue.  Locked-breech guns without a tilting Browning-type lockup will also work reliably.  Tilting barrels frequently have problems...and I suspect that a Rohrbaugh has the barrel tilt through a longer angle than a service-sized pistol.  This is why there are quite a few suppressor manufacturers who are making recoil boosters.

Overstressing?  Possible, but I don't have the design details.

If I were doing it (and I might be), I'd go with a wet can.  Something along the lines of an AWC Abraxas...relatively light and compact.  Hopefully enough so to avoid needing a recoil booster to function.  There isn't much point in putting a suppressor the size of a tube for paper towels on a gun as small as a Rohrbaugh...it kind of misses the point.  You're looking for a total package that is still small.

In any event, I'd be up for a threaded extended barrel.

If you think about the "real" reason for a can, do you really want it to cycle?  

Cycling makes noise.
Extracting empties makes noise.
Sometimes these are louder than the actual shot.

I know someone that makes suppressors for the military and covert government operatives.  Even on bigger guns he will install a slide lock to prevent cycling, to keep things at their absolute quietest (sp?).

Just something to think about.

Send me a threaded bbl and I will try it with my YHM ... but, certainly not something high on my bucket list.

Since I started the thread, I call dibs on anyone sending a threaded barrel for can testing.  ;D

The reason I started this is because I was trying to decide if it was worth having one made. Since it would likely cost at least $400 for a barrel (probably more) and probably has about a 5% chance of proper cycling my dream is dead.

If I do try this on a smaller gun I will be having a barrel made for the p11 since that has a better chance of proper cycling but since this would still not be 100%, you're right, its not high in my to-do list either.  :'(

400 Plus the 200 for the stamp,Plus the Suppressor?
I enjoyed reading this thread>Pillow Post and the New Friends from not
completing the $200 stamp. I laughed out loud. Excellent sense of
humor ;D

Hi Folks: Haven't been on the Forum for a very long time except to look quickly. Have had my pup for about 4 yrs now. It is my daily carry. I previously was intrigued with purchasing a suppressor with dedicated Walther PPS. The only problem brought to my attention was that unless you are LE or Military, using a can on a defensive carry weapon has many legal drawbacks-like juries and jail. Correct me if I am wrong. Given that reality, they are expensive toys.

Deferring to the legal eagles here, Larry, I think you are indeed correct.

Larry.  You are indeed correct.  You do not need a suppressor!

Very true and hard to carry a defense gun in the CC mode with a suppressor.  However, I understand the "what you want" criteria.

Post by: P7Enigma on March 04, 2010, 04:21:10 PM
Can would be bigger than the gun itself! I thought putting a can on a K3 was bad...

When I need to dispatch one of the bushy tailed rats for being too much of a nuisance, they become coon and fox food.  :o ;D
  I live a mile off the main road on ten acres of hardwoods, so there is no shortage of the little critters.
Sad but true.

The farm in Ga. has no shortages either.  They are all over the huge Pecan trees.  They still, just do their thing.

Looks as if you have the perverbial squirrel buffet post there Richard!

Wifey doesn't mind the things as long as they stay off the bird feeders...squirrel proofing a bird feeder however can be challenging at times. We have seen some pretty acrobatic tree rat thru our bay window!...one and half forward gainers, swann dives etc...
