Well, that escalated quickly...

In my previous post, as I was lamenting the fact that I had discovered by day three of MAG-40 that the three "generic" stainless steel magazines for my 1911s were crap, and the feed lips had spread to the point where, not only would they not lock back the slide when empty, but I couldn't even get one of them in the mag well, I added as an aside

the blued ones actually marked as GI mags seem to be working OK.

By the time we had finished shooting the last drills and were about to shoot the qualification several of my blued steel mags were also failing to lock back the slide.

I suppose the "COLT" marked ones have an excuse, since they came with my Combat Commander, which I purchased almost exactly 30 years ago.

Annoying, but nowhere near as annoying as getting that hot brass down my back from the Marine shooting his Ruger LC9S S&W Shield next to me was. ("Mas! The blogger is doing Saint Vitus' Dance!""Is his muzzle pointed in a safe direction...?")

That and it made the Glockenspielers even more insufferable.
