Kind of went off track, into FMJ -vs- HP, fortunately it came back to reliabilty. My experience with 4 different .380's (2 P3AT's, Colt Mustang, and LCP) is that your pistol will tell you what it likes. My LCP may love something that yours won't tolerate. I shoot it in with WWB FMJ, once I know it functions with standard FMJ, then I experiment 20 rounds at a time with any and all of the ones suggested until my pistol and I find our favorite.
