Glock 20C Gen 3 OEM Slide
The Glock 20C Gen 3 OEM Slide delivers factory-compensated power designed for the hard-hitting 10mm Auto cartridge. Glock engineered this slide with integrated ports in both the slide and barrel to reduce recoil and muzzle rise—resulting in smoother, faster follow-up shots and superior control during rapid fire.
Product Description | Specs for Glock 20C Gen 3 OEM Slide
Glock machines the 20C Gen 3 slide from high-strength steel and applies a Tenifer finish that resists corrosion, scratches, and wear. Two compensator ports on the top of the slide and barrel direct gas upward to help tame the sharp recoil of the 10mm Auto, providing better stability and accuracy. This OEM slide brings you factory reliability with competition-ready performance.
