Product Description | Specs for Glock 17L Gen1–3 OEM Slide

Glock machines this long slide from high-strength steel and applies a durable Tenifer-treated finish (or equivalent Gen-era coating) for corrosion resistance and long service life. The extended slide length improves sight radius and muzzle velocity, while factory rear serrations provide reliable manipulation. Built to original OEM specifications, it maintains Glock’s trusted internal geometry for consistent performance.
