A buddy of mine put 5000+ rounds of steel case .45 through his Springfield Armory TRP without a hiccup. Double the number of 9mm through his Glocks and the result is the same, not one problem.

You guys seriously never had a problem with Tula steel cased? Out of a box of 50 I had at least 10 failures to fire in my Glock 23.

Shot quite a bit of it, 9mm .40 S&W, .45ACP, .223, 7.62x39. Never any problems, other than it usually being a bit dirtier than others.

My wife’s Sig P/220 didn’t care for steel case .45 at all, and my son’s non-chrome-lined AR choked on Wolf lacquer-coated .223 after it got hot. Changing the barrel to a chrome-lined CAR-15 pencil barrel from the old Bushmaster took care of his issues.

I don’t like using it in my BCM SOCOM 14.5” AR because I run a suppressor on it, and the fumes from the cheap steel case .223 are particularly obnoxious when they blow back in my face. The rifle runs fine on it, but since I’m left-handed, there’s not much I can do to fix gas blowback, except to change to a Stag LH upper.

I don't chamber a round in any rifle or pistol unless it's stripped off the mag. I used to do it in my Glocks if I kept rechambering the same round. I was doing it because nickle plated cases suffer bullet set back after a while. Too slick on the inside. They use an adhesive to prevent that. Not always effective after a while.

Dropping the slide on a chambered round is what happens in a "push feed" system like most rifles use. The forward edge of the extractor hits the case, is cammed outward far enough to clear it, then snaps back into the groove. The force against it is much greater, both straight back and against the angled surface that makes it cam out. It also usually puts a dink in the brass.

Will this break a Glock extractor? I dunno, but designs like the 1911 with a one piece extractor that is also the spring that powers it can and often are damaged by this. It bends them further than they were designed for, sometimes snapping them, sometimes weakening them, or sometimes chipping off the hook.

OTOH, constantly re-chambering the same rounds from the magazine will eventually shove the bullet back in the case enough to cause a pressure spike.
That sounds wel considered.
