Smooth cycling, zero stays rock solid - ADE Advanced Optics Glock 17 9mm Pistol Slide

Installed this RMR slide on my Gen 1 Glock 17, and it completely changed how I use the gun. My reflex sight mates perfectly, and once sighted in the dot hasn’t wandered at all — even after long, hot range sessions and rapid follow-ups. What I especially like is that recoil tracking feels clean and consistent, with no weird slide feel even though it was an aftermarket swap. It’s clearly machined to good tolerances. For folks with later generations: make sure you know your Glock’s gen — this slide is designed specifically for Gen 1 through Gen 3 and isn’t a drop-in on Gen 4/5/6 without serious gunsmith work.
