Tight Magazine

<< < (2/3) > >>

There have been threads in the past about tight magazines and, if memory serves, the welded ones were at issue.

Wanderer:
Well if you shove a piece of metal into another piece of metal enough times the scratches show up to tell you where the pressure is.   It is scratching at the back of the magazine well.   There are two scratches at the corners of the mag well approximately at the bottom , and an additional larger wear area right before the cutout at the back of the magazine for the hammer assembly,  right in the middle.   I tried to get a picture.

I have 4 no go magazines.
1 with the welded back,  tight in both guns
3 with what appears to be red or brown coloring in the base plate of the magazine in the etching.

I have 2 tight magazines that bind with about 1 centimeter to full insertion.  They will go in,  however they are pretty difficult to get out but can be done.   (These do not have the coloring in the etching)

and 2 that work easily in and out,  1 with no coloring in the etching,  and the other has an extension and does not have the original base plate.

Good Evening folks,

I received a message from Wanderer this afternoon about tight magazines.  I'll do my best to address this here. We test-fired every pistol with two magazines using 115 FMJ ammunition before shipping the gun. Those magazines went with the gun they were tested in, so we never encountered the problem described here. 

Being there is a specific plus and minus number in machining, I’m thinking that you have a magazine at the top of the plus measurement and a frame that is at its minimum measurement causing the tightness. I would take some fine grit emery cloth with a little oil on a flat surface, a flat stone preferred, and sand the magazine sides down a little until it fits your pistol. Using the fine emery with oil should produce a desirable finish on the stainless steel. In addition, if necessary, use a flat file with the emery cloth wrapped around it with the cloth impregnated with oil and try lightly sanding the mag well also. It should only take a few thousandths to accomplish the fit. Another thing you may try is using a good vise to compress the mag a bit. Place some rubber between the vise faces and the magazine and snug it up a little. As you release the grip, the magazine will spring back out a little bit, so see if that works for you as an alternate.  Using the rubber matting will preserve the finish of the mag casing while in the vise. 

I hope these tips help with your mag problem.

Regards,

Eric R.

I am slowly getting the magazines worked out.   I have done it by hand and what I thought would be fairly quick actually has taken quite a bit of time.  I have 2 left that will almost fall free (they are so close) the get tight at the very end of inserting it.   I still have 2 that I haven't started on.  I've been using 150 grit and some 220. 

Hopefully I didn't remove to much from any of them that compromises the function.  Time will tell on that.
