When the original Ruger LCP hit the shelves in 2008, it sold like crazy. It was a pocket sized pistol in .380 ACP that was very similar to the Kel-Tec P-3AT, and was easily one of the most concealable handguns on the market. That being said, the LCP also suffered from a few faults, with the most notable being the heavy and gritty trigger pull and the fact that the slide would not lock back on an empty round to signal to you that it was empty. Ruger solved these issues with the LCP II, which has a single action only trigger to make it much lighter and crisper than the original, in addition to greatly enhanced ergonomics and a slide open on the last round feature as well. Standard capacity is six rounds.
