Yep. I think the potential issue depends mainly on how you do the press-check (I've seen some people do it like a two-handed, almost-full slide rack, almost to the point the ejector is about to kick in), and then second on the ammunition used. Seems .40 S&W, which I still shoot, has had more of a problem historically than most other calibers.C-dub wrote: ↑Tue Oct 31, 2023 8:34 amI have also watched for that. I haven't seen any yet. I also rotate chambered rounds occasionally if/when I actually drop the mag for whatever reason.Jose_in_Dallas wrote: ↑Sun Oct 29, 2023 8:06 pm Be careful about constantly press checking and keep an eye for bullet setback. I noticed that and now I rotate the chambered round and shoot my carry magazine from time to time. I normally carry a Glock and easy enough to visually see a chambered round without having to press check plus when there is a round chambered, can you tell by feeling the extractor.
That said, setback typically occurs--if it's going to occur--when a bullet pushes against a feed ramp. In most normal circumstances (and if you are not pulling the cartridge mostly out of the chamber when doing a press-check), the bullet shouldn't encounter any nose-on resistance when moving slightly in the chamber. So I'd think the greatest risk of setback comes from chambering the round from the magazine, and that a true press-check shouldn't tend to add to the problem.
But, yeah. It's second nature to me to do a press-check almost every time I holster a pistol or sling a rifle. I say "almost" because if I need to do something like reposition the holster a bit on the belt, if all I do is unholster, lay the gun on a desk in front of me, position the holster, and then pick the gun back up (which has never left my sight), I'll skip it then.
