I bought an LCR with crimson trace lasergrips about a year ago. It's pretty nice little gun. In IMO it's perfect conceal carry gun. I'm new to conceal carry and I guess small .38 revolvers are recemmended for new CC permit holders because of their simplicty. I've only shot about 150rds through my gun so I'm still getting use to it. The recoil is a little sharp even with regular .38rds. So I'd rather go out and shoot a full size revolver or auto, but try to shoot the LCR enough to stay familier with it.
I have shot the LCP it's also a nice little gun, but would pick the LCR over the LCP. The LCP is fairly cheap so it would be easy enough to pick one up later. It would be even easier to conceal in some situations.
I see Ruger just came out with a 357mag LCR. I cannot imagine shooting a lot of 357 rounds through it, but it would be nice to have the option.
I use a Uncle Mike's inside the pant holster for the LCR.
