I've owned a Kel-Tec P3AT, original LCP, Pico, and LCPII. I've not had a Bodyguard or Kahr.
Of the ones I've owned, the LCPII is my favorite by a large margin. It has good sights and the trigger is excellent. Mine has never malfunctioned that I can recall.
It's what I carry when I can't carry anything. I'll maybe look at a Max one day, but I probably don't want my tiny hideout pistol to be less tiny.
My hands are XXL. The micro-380's will beat my hands up a little bit if I don't hold them perfectly. I shoot maybe 3-4 magazines per session, keeping the practice sessions short so I won't develop a flinch. I can shoot them almost as well as a snub 38 at seven yards.
Bring out the torches and pitchforks! I load mine with FMJ, preferably some faster foreign stuff.
I have the little Desantis pocket holster for it. Good for back pocket (walking the dog) or in the breast pocket of a big flannel shirt (cool weather).
Warning: This pistol has a nice crisp trigger and no safety. If you carry it without a pocket holster, you will eventually shoot yourself.
