I have a P238 Equinox. I used to carry an S&W Bodyguard 380 and then a Ruger LCP.
I pocket carry with a DeSantis SuperFly; used to have a DeSantis Nemesis. I strongly recommend the SuperFly.
Out of the BG380, LCP, and P238, the P238 I can get tight groupings at 21'. I can barely get any shots on target at 21' with the BG380. The LCP is okay. Accuracy at 3' is not a problem with any of the guns which is a more realistic scenario with a .380.
I have a lot more confidence in the P238's trigger pull than the long DAO pulls on the BG380 or the LCP. The additional weight of the P238 makes it much more pleasant to shoot at the range as well; if you don't enjoy firing your gun, you won't end up with enough practice to be confident using it when you need to.
I carry cocked and locked. Do enough dryfire drills with flipping the safety off and you'll be fine. The safety switch is much easier to use than the BG380's.
The P238 eats up the Buffalo Bore "+P" (yes, I know there is no definition for .380 +P) stuff just fine, and the extra recoil is much less punishing than on the polymer-framed lightweights.
I do not notice the extra weight in my back pocket--we're talking micro sized .380s here.
Biggest downside? The Ruger LCP is easily had for $299, and the P238 is... a lot more. Expect to pay $40 - $60 for extra P238 mags as well, although I hear Colt Mustang mags work.
