Taking direct feedback from pistol combat instructors and shooting professionals who were using our Version 1 and Version 2 slides, the Version 3 pattern was designed with tapered serration channels for an increased purchase on the slide when performing press checks or malfunction clearing drills, ensuring positive operation of the slide under duress or while in any wet, muddy, and/or visceral conditions. Another innovation is the dual compatibility optic cut, which is milled for either a Leupold Deltapoint Pro or a Trijicon RMR when using the supplied aluminum shim plate and screws. FEATURES: Stripped slide machined from 17-4 Billet Stainless Steel to have tighter tolerances Mfg: Grey Ghost Precision
