I shoot short-tailed PPKs and a PPK/S and don't get slide bite. I wear large size gloves (work, not shooting gloves) but compared to some other guys. especially those who work with their hands, my hands look a lot smaller. I guess my hands are "large but slender." I don't shoot a lot of .380s and while I note the pressure between my thumb and trigger finger, it's just that: no skin broken, no blood.
I can't afford to shoot 8-9 mags of ammo and don't think I need to. I don't think it's a 50-round-at-a-time gun. I shoot a couple of mags at 7-8 yards to verify my shooting and if that goes well, I'm done. If I sot a lot more I might get soreness; I see the potential, but still no slide bite. If the slide doesn't bite on the first round, I think you're good. If it bites later on down the magazine, it's likely your grip has changed.
My PPs are not tactical guns, they're SD pistols. And fun to shoot!
