Re: 1911 Magazine Question
"every part from every manufacterer will interchange"
In a day when "spec" seems to be a four letter word, I wouldn't make book on that.
FWIW, I had an interesting problem with a ten-round 1911 magazine I bought for pins. Somehow I didn't notice that it had no tab on the front to provide a stop. So I slapped it into the gun and tried to load the first round. The slide wouldn't run forward. I tapped it. No go. So I try to remove the magazine. It won't come out. Now I am holding a pistol with ten rounds in a magazine and I can't get it unloaded, nor can I fire it.
So I called an alibi and problem. With everyone well back, I went to work. It took me five minutes to get that magazine out. What had happened was that with no stop to substitute for the floorplate lip, the magazine went all the way up and wedged itself in high enough to block the slide. What a pain. No danger, but my face was pretty red, as I am supposed to know a bit about 1911's.
I threw that magazine away and bought another 10 rounder from another company that has a stop welded on.
