Have one of these and it is the best for CCW, think my BlackBerry is bigger and heavier. At the range using FMJ and JHP rounds, no feed problems and the 8" metal plates get knocked down. I wouldn't want to be shot with it, figure dump a full magazine would be like a 00 Buck blast, so while not a 45, it's something. I had to replace the Magazine release, super service from Kel Tec...called and part showed up next day. Easy to work on too. My fault with plastic mag release, need to hold button down when putting in or taking out magazine, letting it "click" just wears it out. If you want something super little, easy to hide/carry, very light, no recoil, not a rim fire, and low price, this is it.
