in the light weight guns, a good bullet crimp is needed as pointed out above... 9mm only gets a taper crimp, & may prove to be problematic ???
I just bought a 38 Special ( rated for +P ) LCR-X ( with exposed hammer )
I also have an air weight J frame in 32 H&R magnum, & an Air Lite L frame in 44 Special... I use a Redding Profile crimp die on all my light weight & magnum snubbies after having some 454 Casull bullets jump crimp in my Alaskan... Lee Factory crimp dies also work well, but I feel I get more consistent & tighter crimps with the Profile Crimp die...
while the 9mm LCR is heavier... I'd still be concerned about bullets pulling crimps with factory ammo or a standard taper crimp handload...
