Slide Construction and Features

The Sentinel slide is steel with a black nitride finish and features front and rear serrations along the slide body. The RMS pattern optic cut accepts Shield RMS footprint optics directly. 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.

Threaded Barrel and Slide Parts Kit

The included G43 compatible threaded barrel carries a black nitride finish with a 1/2x28 thread pitch chambered in 9mm. The black nitride finish on the barrel coordinates with the black nitride slide for a fully blacked-out combination across the complete kit. The black oxide thread protector includes an O-ring for secure retention on the 1/2x28 threaded muzzle when not in use. The complete G43 compatible slide parts kit includes a metal guide rod assembly and a front and rear short sight set compatible with Glock G43 and G48 dovetail cuts.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify fitment with your specific Glock G43 or G43X compatible frame and components before use. Verify local and state laws regarding threaded barrels before purchasing.
