If you want a Colt-spec 1911 to run with 230gr ball the way legend says a 1911 should run, this is the magazine for you, especially if you are having smokestack jams, or what appears to be the gun trying to double feed, even with Colt mags from even the C-marked/Checkmate OEM supplier.

The problem is that modern mags are tailored to feed shorter HPs which need to pop free sooner to hit ramp straighter and not climb at so steep an angle lest the HP grab roof of chamber. When shooting heavier ball, the heavy bullet does not recoil with rest of gun as briskly as do lighter rounds/inertia, the 230gr is left behind enough the top round pops free, and then on slide slide return stroke it strips a round out of magazine under the loose round, and often that loose round gets knocked vertically to be smashed by slide as it attempts to close, causing the classic smokestack on a live round.

The GI mag has essentially only straight fwd taper in gap between lips, with no flare between them for earlier release, so, even though round does get left behind under recoil to a degree, it never pops free, and these GI mags have the far more effective GI D/half-moon raised dimple whose straight edge catches cases to prevent further fwd shift on the follower.

They also allow 230gr ball to feed as designed originally, with rim of round low and sliding UNDER the extractor as a Mauser at feeding as slide closes, where more modern designs often release so early and straight as to have extractors popping over rims at slide closure, accounting for the lively market in extractors from major name magazine suppliers, as this extractor design was never designed to flex outboard to that purpose, which would need a pivoting extractor for that sort of movement.

These are likely NOT the magazines you want if shooting modern ammo. For THAT, use the modern mags, and live with modern problems which have plagued the 1911 with "advance" after "advance" (fix after fix) in attempts to get a realiable a gun and ammo combo as the original.

Excellent magazines. Bought these to replace older mags that had feeding issues. These worked and functioned flawlessly for me.

I use these magazines in Wild Bunch matches and they function flawlessly with 230 grain ball in S&W 1911E, Desert Eagle 1911G, and Ruger SR1911.

The magazines had failures to feed factory fmj in a les baer and an ed brown.

The mags were a waste of money

I shot over 100 ball rounds through these magazines and had no problem at all. I also shot 3 magazines of LSWC, naturally expecting a feed jam, but had no problems. I will buy these again.
