By force of habit, I never use the slide release lever on any of my pistols...I pull back on the slide and sling shot the slide forward. For one, this makes sure that I have uniform muscle memory no matter which pistol i'm shooting. This motion also coincides with clearing a stovepipe or other malfunction. Also, most of the time this ensures proper round feeding no matter what kind of ammo you are using, by getting that extra bit of force of the sling shot vs. just using the slide release lever.
