Tight Magazine

(1/3) > >>

Wanderer:
Of the magazines I have 1 of them appears to be welded rather than sanded, but it seems extra tight and it is hard to insert and extract.   It seems to bind up around the 3rd hole down without rounds in it.  Comparing it to the other magazines that move freely  I don't see anything obviously different other than the back of the magazine has a weld mark along the back, versus the others.   It maybe it is less than a hair wider at the weld at the base plate where the weld sticks out a tiny bit more at the back of the magazine.  Has anyone seen this before?    I have to grip it with my fingernails and pull a bit to get it free but the other magazines aren't like this.

Also it seems the magazine release on this one is quite a bit stiffer than the other,   It still functions but it can make it a little more difficult to extract.

The other day I had a few issues with failure to feed so I disassembled and have now cleaned and oiled it up.   I didn't see anything that would indicate any kind of obstruction it the magazine well for the tight magazine issue,  nor anything that impact the magazine release as far as I am aware.   Lack of luberication may have been the issue with the failure to go into battery over the weekend.

The gun likely was rarely if ever fired prior to the range trip the other day,  but it definitely was a little dry.   I did notice there are a couple light scratches at the back of the magazine well.   I don't think they are big enough to impact anything but they are there.

I tested the magazine in the other R9 and it is even tighter to the point I didn't want to force it.  it starts resist by first or second hole,  it seems tight front to back.  Nothing I can detect with the naked eye though on what is causing the binding.

tracker:
That is unusual. Eric may have a thought for you. Have you tried buffing it?

Wanderer:
Not yet,   I'm going to get my calipers out and take measurements to see if I can figure out what is going on.   

I did take it apart,  cleaned it used froglube on it and it still binds.  it will slot in the 6K series with pressure,  but the 4k series one still doesn't like it.   I had my wife take a look too since I wasn't seeing anything and nothing stands out between the magazines  I've compared it against. 

If it just a tiny out of spec  maybe lapping it down a little might help.   But definitely would like to have a better idea before I start messing with it.

Wanderer:
I ran through all of the magazine i have.

Only the one with the welded seam is tight in both guns.   After frog lube it will slow in the 6k serial numbered one,   but is still very tight in the 4k one.   Interestingly all the other magazines slot in the 6k one  easily however 4 of them,  2 of which are brand new, are very tight in the 4k seral numbered one. Those 4 have the sanded seam.

The binding appears to be front to back rather than side to side.
