G21 Submarine Aftermarket slide
Compatible with G21 Gen 3 applications. Slide is stripped. Channel liner is the only thing included with the slide.
The Submarine design incorporates 3D surface machining to create the unique front ports. The ports differ from the 2.5 axis milling which is most commonly done for slides by adding depth and changing perspectives as you view the slide from different angles. Although the front doesn't have the standard cocking serrations, you'll find that the ports are easy to grip for slide manipulation. The corners are beveled and the long top edges are chamfered for an improved sleek appearance. Once you see the 3D ports, you won't want to settle for the common milling approach again.
