SIG P938. I bought it four years ago, to replace another compact carry pistol, thought I'd put a few hundred familiarization rounds through it, then maybe another couple hundred a year, but I've been shooting it almost to the exclusion of every other gun I own, with well over 3000 rounds through it.
I enjoy the challenge of shooting such a small, light gun, as 90% of the handgun rounds I've sent downrange in my lifetime have been through 1911s.
