I recently upgraded from a CW380 to the P380 Kahr. Before people ask, I upgraded because I just wanted to. First 200 rounds, I had a few FTE, which I believe was due to the breakin and a little me, limping. I have found the rounds it likes most the Hornady XTP rounds. I can tell by just chambering the round. It sounds smooth. Sounds better than the Hornady Critical Defense when chambering. Well today I put 50 rounds of Hornady through it which went flawless. A mixture of both the Hornady XTP and the CD. A side note, I did polish up the outer area of the barrel which helped with the smooth action. I'm very pleased with my P380. Note my CW was also flawless a after breakin.
