Might want to make sure you can shoot .357Mags out of the LCR. The one I own is .38Special ONLY! The rounds may look the same, but they are most definitely NOT the same rounds and are not interchangeable unless the gun is designed to shoot the .357Mags.
.38's in a gun designed for .357Magnum = OK
.357Mags in a gun designed for .38 Special = NOT OK ie. gun goes KAPLOWWWW in your face.
