as a matter of fact even a 9 MM, 38 Super, 10 MM will all fit into the 45 acp 1911, they will all interchange.
they just will not all work, Like the 9 MM and 38 super will not work worth a flip as the lips on the mag are to tight, and if trying to use a 9MM / 38 Super bollett in a 45 mag that won't work either, as they just pop out the top.
the 10 MM cartridge seems to do Ok for me, but a dedicated 10 MM mag would be better.
we can go into just how I know all this but I had rather not!
but with all the funny stuff being said yea, any brand 1911 mag as long as its single stack and the correct caliber will/should work for you.
Mec =gar makes a good mag and usually reasonbally priced, lots of manufactures use them.
the good thing about the non removable magazines are you don't have to worry about he base popping off and you dropping all your Bolletts on the ground--and No I have not done that --YET!-- but have seen it a few times.
