For me this too. Some guns I notice more by recoil impulse difference. Some by trigger rest (or lack of) feel. And yeah, occasionally I pull the trigger and not realize the bolt or slide has locked back.Being mostly a Glock guy, I tell more by trigger reset. I'm sure, were it not for that, I would likely feel the lack of slide returning to battery. I always feel when my AR runs dry by the lack of forward bolt movement.
More often I think I ran it dry and then do a “oh, I’ve got another round left”
