I've noticed that mine will sometimes seem to drag about the last 1/16" of an inch. It is just enough to feel it "lag" on cycling. I can duplicate it with no ammo in the gun if I hold the trigger back and let the slide down. The slide will stay back just a bit. As soon as you let pressure off the trigger, it closes.

Does yours do this?

How many rounds do you have through it? Mine did that at first...3-400 rounds in, and it's no longer an issue.

Cycling by slowly hand, yes, and my P320's do, too.

Cycling when firing a round, not at all.

No such issue on mine.

I see it when I'm dry-firing and only cycling the slide a small amount. I don't experience it when fully cycling the slide, or while firing.

Mine did it once in first 100 rounds. I’ve ran anothe 400 with zero issues, soft shooter, very accurate, with an amazing trigger.

Shoot your gun. If I had any issues I never noticed them through 4000 rounds fired. My question is, when do I change my recoil spring assembly? Sig says 2500 rounds. I could not find one so I bought another P365.
Since, I now found one and bought a spare but so far no need to change the original one out.
