I used to frequently shoot hundreds of rounds in a session, usually takes about a hundred rounds to settle in. I only shoot S&W revolvers now, after a hundred rounds, I stop and make sure no screws have backed out and use a brass brush on the front of the cylinder and wipe down the back of the cylinder, if I don’t it will bind.

Check your cylinder gap. I had (still have) a S&W 22 LR that did that. Bought it new in the 70s. Had a 0.006 cylinder gap on one side and 0.001 on the other. Filed it even and it hasn’t had a hiccup in the 40 years since. And it is the only revolver I’ve fired hundreds of rounds thru at a sitting - and 22 rounds are notoriously dirty!
If I was worried about a strain screw backing out, I’d use Locktite on it. But mine has now gone 15+ years without budging. I don’t mind shooting 100-150 rounds at a time thru my J-frames, 38 special only for that, but they have never had a hiccup of any kind. The day one malfunctions on me, it will be a first.
When I CCW, I start with a clean gun. I don’t expect to ever shoot into double digit counts defensively. Besides, if I carry a reload of my J-frame, it is in the form of my Beretta Pico.
