Welcome to DRTV, it sounds like you covered it. It's a personal preference, but trying some of this ammo, some of that, some different hollowpoints, different mags, to ensure no hiccups is always comforting.
IMHO, a box or two of ammo, with some carry ammo mixed in, rapid fire drills and such, rotating mags, and a good cleaning (mags also), should do the trick.
Sometimes the "leetle" pocket guns can be finicky with certain types of ammo. When I first got my Kel-Tec P3AT .380, the Golden Sabre JHP's would not feed reliably, but Cor-Bon, or Speer Gold Dot's would work just fine.
A slight fluff & buff of the feed ramp, and another 50rds, of target ammo, and it eats all JHP's everytime.
FWIW, on your next range trip, start with some target ammo, get it dirty/fouled a bit,....than shoot your defensive carry rds. If it keeps on firing, your set.
