If I am truly going pocket carry, I go with my Kahr P380. I also have a Kahr CM9, but it is still not really a pocket gun in the way that the P380 or Ruger LCP is. If you do not regularly pocket carry in slacks, the PM9/CM9 should be fine for most people, though.
When possible, go IWB and carry at least a 9mm. But when necessary to pocket carry, you shouldn't feel bad for going .380acp. It's better than no gun or a dinky .22lr or .25acp.
.45acp, .40 S&W, 9mm, .38 Spl, .380 acp, 22lr
12 gauge, .223/5.56x45mm, 30-30 Winchester
