1911 mags…

[Old Bear]

I usually run Wilson service mags and have never had an issue.

My RO runs just fine with springfield factory mags and loves the one Wilson Combat 8 rounder that I have (need to look into getting some more of those.) Picked up some old colt "surplus" magazines for cheap and it didn't like those at all.

Do the surplus mags say Colt on them?

Do the surplus mags say Colt on them?

They do, actually. Base plates are stamped "Colt 45 Auto". They tend to run ok-ish during a mag. First round tends to try and jump past the feed lips and lock the whole action up. I've also had trouble with the slide lock using them (both not engaging and releasing immediately upon seating the mag.) Haven't had any of those issues with my other magazines, though I do wonder if part of it might be worn magazine springs.

Edit: I did some more googling and it appears these are actually triple K brand and not actual Colt. That actually explains a lot for me.

Every one tells me they have never had a problem with Kimber 8 round, but I have several and every once in a while they fail to lock the slide back. I have mil spec 7's and Chip 10's and have never any had a problem with them.

I run Chip McCormick Powermags with Wilson springs and followers as duty mags. Wilson Service Mags and 47D's are also very good. Don't forget about Mec-Gar mags. I have several 8 rounders that have been flawless. I have several surplus Colt mags in my range bag that I've really never had any issues with and they were picked up cheap out of a bin in a Military Surplus store.

Tripp Research Cobra Mags are the best out there IMO. I run the hell out of them in my 1911's that I shoot USPSA matches with.

I run these in my 9mm 1911 and I don't recall ever having a magazine related malfunction.

Apparently I'm the only one that likes Check-Mate mags with hybrid feed lips.
