My P380 seems to like about any round that goes in it. The only round that did not work well was 102 grain golden sabrea and that was because the round was hitting the inside of ths dlie lock and pre engaging the slide stop. Went bang every time but the slide stop issue was something I ahd to work out. I got a new slide stop lever from kahr but I have since shot up all my remaining 102 godlen sabres and just moved on to other good defense rounds. I hve no issue withthe 90 hp corbona nd the borbon powerball, which I am carrying in it now. Not so sure if the P380 kahr is picky. Most of the bigger kahrs are certanly not ammo sensitive. My PM9 will shoot anything that goes into the pipe...
