I’ll second Slide-Grease from Brian Enos. I use the thinnest formula on 22lrs, 9s, and 45s… A little goes a very long way. I use a foam Q-tip applicator and work in a very small amount in the slide guide as well as the rails. After 500 rounds the stuff is still there!
I’ll second the slide racking feel as well… it feels like an air hockey puck…
