The Z320 XCompact gun-mods come standard with a SIG Flat Faced Trigger, Octane Slide with Trijicon RMR compatibility, PRO Barrel and Zevs fiber optic Combat Sights. The Octane slide was designed by founder Al Wolf and is the perfect storm of purpose driven features. From the modern lines to the channels on the top of the slide, The Octane is just hard to not look at. Aggressive slide serrations help with manipulations and create a lighter slide, allowing the pistol to shoot flatter and maintain sight picture more easily during follow up shots. When performing manipulations, the edges and angle of the cocking serrations actually drive the fingers further into the slide to produce a better purchase. Regardless of the environment, youll find the grip of the Octane to be more than adequate.Features :ZEV Z320 XCompact Octane Slide, RMR Optic Cut, Titanium GrayZEV Z320 XCompact PRO Barrel, Black DLCZEV Fiber Optic Combat Sight SetZEV RMR Cover PlateSIG Sauer P320 X Series Flat Face TriggerTwo 15 round SIG Sauer P320 Magazines
