Bersa 380 both of mine run fine I think in the KelTec a lot is limp wrist . Minne has always worked fine 2000+ rounds I let another guy shoot it and it jammed each and every shot. Wasn't pistol I loaded and emptied mag fast as I could was him.
My PPK/S I always use the hottest 380 I can find Corbon or Buffalo . Europe 380 hotter than American Or use a little lighter recoil spring.
Bersa works on any ammo I have tried in last 7 yrs.
