Slide Construction and Features

The Sentinel slide is steel with a black nitride finish applied over the exterior. Black nitride diffuses nitrogen into the steel surface under heat to produce a hard, corrosion-resistant layer that is part of the steel itself rather than a coating sitting on top of it. Front and rear serrations are machined into the slide for positive grip during slide manipulation from either end. The RMS footprint optics cut on the top of the slide accepts RMS pattern optics directly, and the included RMS cover plate covers the cut when no optic is present.

Copper PVD Threaded Barrel and Slide Parts Kit

The included Glock G43 compatible threaded barrel carries a copper PVD finish at standard G43 length with extended threads, a 1/2x28 thread pitch, and a 1:10 twist rate chambered in 9mm. PVD, or physical vapor deposition, is a vacuum-based coating process that deposits a thin, extremely hard layer of material onto the metal surface at the molecular level, producing a durable finish with a distinct color appearance. The copper PVD finish produces a warm metallic copper color across the barrel exterior that contrasts against the black nitride slide, creating a distinctive black and copper two-tone combination across the complete kit. The matching copper PVD thread protector carries the same copper finish and includes an O-ring for secure retention on the 1/2x28 threaded muzzle when not in use. The complete slide parts kit includes a metal guide rod assembly and recoil spring assembly. A front and rear short sight set compatible with Glock G43 and G48 platforms is included.
