I currently conceal carry here in Costa Rica an HK USP Compact .40 S&W or a Walther P99AS 9mm and I'm debating which pocket handgun to purchase. The reason I am looking at purchasing a pocket gun is that it would make it much easier to conceal carry at work and the beach. Therefore, I'm looking at the Ruger LCP and the S&W 642 j frame revolver (.38 special). I am primarily leaning towards the S&W 642 because of its solid reliability and much better stopping power but I'm attracted to the Ruger LCP's concealability, higher mag capacity, lower price and the fact that it is a semi-automatic which I prefer over revolvers.
Based on your experience in CCW in the US, which handgun would you recommend? Should I be looking at the Glock 26? Is it easy to carry it in a pocket holster or is it too bulky for this type of carry method?
