When I first answered this in early summer, it was my SIG P365. I do love that gun, and the 12+1 in a very concealable package, and being nearly a pocket gun with a 10 round mag, is attractive. However, since I bought it, my 3" Taurus 856 Defender gets most of my carry time. It is only 6 rounds, but a revolver has advantages. The rounded shapes are much more comfortable (for me) and IMO conceal better (even if it prints, the several round lumps don't scream out "GUN" to people the way the sharp corners and edges of an auto do). With a Zeta 6 speed strip (a faster design than regular speed strips, but still flatter than a speed loader), I can do fairly quick reloads and have 12 rounds available if needed.
