The LCP is a great little gun. It's surprisingly accurate. You may want to beef up the grip with a Hogue slide on or replacement grip and there are Wolff recoil springs that are stiffer than stock.
All three guns super cheap in your hands, though, and you wonder if any will still be in one piece after 2-3k rounds.
Taurus also makes an LCP knockoff, the TCP that has real sights. Also small, frail, and cheap.
