haven't touched my smith model 52 in many years and just got the itch to shoot it. loaded a few rounds and tried them in the basement and had some feeding problems. i found i did not have the wascutters seated fully flush in the case there was about 1/16th inch exposed. i also noticed my slide seemed really sluggish so i stripped the gun and cleaned the gunk off the rails and put a couple drops of clp on them. wow what a difference! the slide gained a lot of velocity. no malfunctions now. time to hit the range!
