I'm quite new to 1911's so forgive what might be a simple question. I just can't find a straight answer.

Who makes 9 or 10 round 9mm 1911 mags with pre-drilled bases (for bumpers)? I just bought some Mecgar mags and they were not drilled. I drilled one myself but without a jig & I've bubba'd it good. So that's a spare now :)

Thanks!
 
Kinda relevant, but has anyone drilled Mec-gar mags with the welded baseplate for bumpers, and which bumpers might fit them? I've got a bunch of 8-rounders for my 10mm that I'd like to add bumpers to if I could.
 
I just tried to do this. The metal is very hard, and my snap-on drill bits (brand new) had trouble biting in. I have no method of holding the mag without crushing it, so I could not properly center punch the welded baseplate. When I finally got the drill to bite it was off center. I was attempting to install some PETG 3D printed bumpers.

While more than twice the price, pre-drilled seems to be the way to go. Unless I make a jig that can hold the mags under my press to drill them. I'd spend more in time and materials to make a jig vs. buying predrilled.

Make the jig "just because you can". Try a Dremell stone first. It may be it is just hard cased.

Not the problem. It will be because of too high a drill speed.

Center punch where you want the holes and use a drill press capable of low speeds. Put the mag in a drill press vise or other sturdy setup.

Most everyone knows someone with a drill press or milling machine if you don't have one yourself.

Take the follow and spring out, cut a some flat iron the same angle as the base, lock it in a drill press vice, and than center punch , Cobalt brill bits will cut hard steel.

If metal is hard, use carbide drill bits; not masonry bits, but actual Carbide fractional drill bits. Available through industrial supply companies, and not stupid expensive either; but being sold carbide, they are brittle.

I put the mags in an old 1911 frame that was deactivated and clamp the frame in the vice - no crushed mags...
