reliable 1911a1 magazines.




Hi Guys.

I had bought 2 original colt magazines in good condition. My question is 1 of them is .35th wider in width.and its hard to take it off the gun.Is it common to find mags like this? Sure the soldier will throw it away.

regards
mag357.

You're serious is .350 thousandths difference. That is almost 3/8 on an inch. Surely you mean .035 which is still too wide. Take it back to where you got it, if that is possible.

Hi Bdavis385.

You are right it's .035 extra in width. I'm not going to use them just to have extra mags with my 1911A1 for display only.Just curios if it was common with old military magazines? what I know is that they had a standard measurements and this 1 is out of tolerance. It works but to pull it out from the frame it's hard. It's the first one from right side.

Hi mag357,

Recently, I bought a spanish Ruby pistol mag which was slightly too wide, like your 1911's one.

I put it in a bench vice (using protection of course) and I tightened it carefully. After this treatment, it was perfect without any damage.

Regards

Hi Berghi51.

It makes me think of the problems the soldier face with this issue in the field.Exp if the need arise to use the gun and magazine jams the pistol? This one for me it's an original colt with pin base and without any markings .I'm more interested in real problems they faced.My be some one know some stores.

Regards.

Remove the follower and look at the top of the baseplate on the inside. What does it look like?

I think you are right. Colt's mag have the back edge more rounded than contractor's mags like your's and are slightly thicker but they can be extracted from the frame without drag.

The top of the base is the same than the top of the base of my 2 Colt mags (1 without any markings and 1 Commercial/military).
Colt mag is more ajusted with the frame. Finish is better than Contractor's one ( less steel used was good).
During WWII, lot of pistols needs the two hands of soldiers to change the mag. The IPSC (eject and feed) style wasn't in the mood and mags weren't dropped onn the battlefield.

Don't worry about your mags they are fine and fit well your 1911A1 pistol.

Your first picture in post #8 is very interesting. I always thought that the "tunnels" for the base pins were solid all the way across the width, but yours have openings in the middle. I learn something new every day. I look to Doran for an explanation, as I consider him the expert in this field.

In my 2 Colt mags, "tunnels" of the top of the base are like mag357 pictures, not solid.

I posted a reply but for some reason it didn't appear.

I mic'd a 1950s Colt magazine and Ballester 36522 that I have handy. The Colt measures .533 inch and the Ballester .550 inch. I've not had issues the few times I've used Ballesters for shooter magazines but a top tolerance magazine body and bottom tolerance magazine well might cause some interference. Others have reported very tight fits using Ballester magazines in USGI pistols.

This 36522 Ballester magazine has the relieved pin tunnels per the las rev I have of the magazine dwg. I suspect the relief avoided the deep hole drilling oprn with such small bits. I've also observed this relief in Sistema magazines and occasionally in late contractor pinned magazines.

So I believe you may have an unmarked Ballester magazine. Ballester magazine springs sometimes have a 90 degree leg under the follower rather than the normal looped end if your's has that.

Hi Doran.

The 1 to the right is the one that I have the issue with.So it's not a colt mag?
They sure looks the same from out side. In fact you are right about the spring.Thanks for your help.

From it's features I would say Ballester, although unusual to see one without some kind of stamp/serial.
