Why Choose an Aftermarket Slide for Your Glock 17 Gen 3?
Factory Glock slides are functional, but aftermarket upgrades open the door to better performance, optics compatibility, and personalization. Our Gen 3-compatible slides include:
-
✅ RMR Cuts – Ready for Trijicon RMR, Holosun 507C/508T & similar optics
-
✅ Ported & Windowed Designs – Reduce slide weight and improve balance
-
✅ Threaded Barrel Compatibility – Allows use of comps and suppressors
-
✅ Stripped & Complete Slide Options – Build your own or go ready-to-run
-
✅ Premium Finishes – Available in Black Nitride, FDE, OD Green, and more
All slides are engineered for Glock 17 Gen 3 frames only and are not cross-compatible with Gen 4 or Gen 5.
