Keyhole Mags

after conferring with some real experts, it seems I need a "keyhole" magazine to make my 1912 M1911 complete. This esoteric Colt magazine is the same as a usual lanyard loop two tone M1911 magazine, except it has a "keyhole."

I didn't even know such an animal existed. Learn something new every day..... Ah well, I might find turtle teeth in my mailbox first......... At least I have an excuse for using a standard GI magazine..... If anyone has a keyhole mag in the bottom of their range bag, shoot me an email......

Was there a reason for the keyhole? Were they afraid the feed lips would be too stiff?

Depending on how dedicated you are to actual history, if you care, you could always cut your own with a drill, hacksaw and some sandpaper.

Stress relief? Debris exit?

What did the experts give as the reason for aforementioned keyhole?

Keyhole magazine is new to me as well. But quick search on ye olde internet reveals:

"The cut and hole were added to add more flex to the tube. Prior to this modification there was issues with the magazine cracking at the feed mouth. Better metal was found and replaced the more brittle metal at about serial number 30000 and removed the need to add the key hole modification"

Perhaps the keyhole supported the mag cap used to cover the magazine to keep dirt out.

Brittle metal causing cracks in the feed lips, the keyhole allowed it to flex preventing failure.




I love Google sometimes.

I once encountered a TT-33 magazine with a hole. The hole acted like an auto switch for the poor TT.
