Using 158 gr 38 spl RN from about 30'. I was shooting to the left and a little low. Shot my Beretta 92 FS Brigadier 9mm next and it was like night & day as far as kick.What ammo were you shooting? 38 spl or +P? The kick must not have been to bad if you shot 50 rounds. The LCR +P model is feather light so it doesn't have much weight to absorb the recoil, especially shooting the +P rounds.
Were you able to be accurate with it and at what distance were you shooting from?
