A friend has the 42 and I have a 43, both capable, but as mentioned above, not a pocket pistol ... My reason for the 43 was because its only very slightly longer but the benefit of 9mm
To make a short story shorter, because of the weight & bulk it just doesn't fit with with my dress code at work, although the under shirts with the built in holster/retainer worked but not terribly comfortably. I've tried an LCP, BodyGuard, LCP2 and a few others ... Looking for not just short, but slim as well.
Then picked up the Colt Mustang XTS ... WINNER WINNER CHICKEN DINNER!
It's a 380, and IMHO true pocket pistol. About the same size/weight as the LPC ... I can carry it in slacks, sweats, shorts; its much smoother shooting than the LCP and more accurate, at least in my hands ... A head shot (styrofoam head) at 30 yards, 6 out of 7 shots.
When I was telling my FFL about it he pulled one out of his pocket and said, "another case of You Get What You Pay For".
