I have had nearly all the .380s mentioned here and enjoyed them (never did like the Colt Mustang, but kept it for 30 yrs. just b/c it was a Colt).
I finally got to the point that I realized there were 9mms nearly as small as the .380s, so I decided to divest myself of anything smaller than the 9mm, (.22 magnum S/W Pistol I loved and my Beretta .25s and .32s).
The Glock 42 shot wonderfully for me, better than the G43 did in my hands.
LCP 2 in whatever pocket holster you like, cheap , reliable and honestly IMHO it's the best pocket 380 on the market. Personally for me I have yet to find a 9mm that meets "pocket carry" for me but then again I am just a young hipster who wears skinny jeans occasionally
But why not carry a 9mm the same size like a sig 938 or Kahr 9mm or ruger lc9s????
One I haven't seen mentioned is the Kahr CW380. It's another good option for a "pocket gun"
