If you want a pocket holster (and that's the way I carry my own LCR) take a look at the Blackhawk Pocket holster. (About $12 to $14 bucks at Bass Pro Shops, and same on-line)
The Size 3 is marked for "small 2" barrel revolvers" but it DOES NOT fit the LCR. The BH website says to use a Size 4, for "compact 9mm semi-autos".
I took the Size 3 back and exchanged it for a Size 4 - - - - perfect fit.
Seems that some of the pocket holsters that fit pieces like the S&W J frame don't fit the LCR well because of the slight swelling of the body behind the cylinder and the shape of the trigger guard.
BTW, BHawk is the only pocket manufacturer (other than DeSantis) that clearly labels one size for the LCR.
