Here's some thoughts on the Sig P238 for POCKET carry..
1. It does NOT have an ambidextrous safety. Therefore, you are limited to carrying it in the right pocket only. I am assuming that you are right-handed, carrying with one in the pipe and with the safety "on".
2. It does not conceal as well as the LCP (using pocket carry)....but it sure fires a lot better. Follow up shots are a breeze.
3. It makes a very comfortable and concealable IWB gun. I would opt on carrying IWB over pocket carry.
4. Super accurate for small gun. Very light recoil. Feels solid and well made.
5. For pocket carry, the Sig P238 will not work in jeans. Because the 238 is flat...it has a very recognizable "print" that screams "gun". Also, drawing it out quickly from the pocket is a bit slow. (for me) I would consider one of those super light Smith and Wesson j-frames instead (for pocket carry) and use the Sig P238 as your IWB gun.
Ok... here is some disclosure:
Yes, I would carry the Sig 238 IWB appendix style.
And yes, it is a little scary...since it is pointing at a very special place.
