I carry an LCP. As a Carry Piece it is a fine pistol (imho) ESPECIALLY in the hot & Sticky months (when I'm in Florida). But it is NOT a target pistol, the sites suck, a very small grip, it kicks a bit (because of the light weight). and IMHO the .380 Auto round is on the hairy edge of being effective as a SD round.
But it depends on the Situation and the Tarrain (as they used to say in Infantry School). If I was not in shorts and a tee-shirt... If I had to walk or drive through "Gang Land" or similar places, I'd find a way to carry at least a 9mm (short) double stack, a la the Kel Tec P11 (min), or the next step up, SR9C or equivalent (Glock, Sig, XD, etc.), and an Extra Mag to boot!
If ONE is new and inexperienced to pistols in general, and does not want to spend the time and $ to train, then look that LCR. It's a lot bigger than the LCP, but you can't beat the simplicity of a revolver (imho) that really will never fail you, and the .38Spl+P SD is Very formadable.
And as for the LCP pocket carry, I use "cargo shorts" and "cargo pants" when I travel in the winter. I can easily get to the cargo pocket when sitting in the car or anywhere else, without standing up, and without haveing the rearange my other pockets. It looks like I have a notebook or camera or wallet in the pocket.
StaySafe,
