The CMC Triggers Kragos is an aftermarket slide designed for Glock 19 Gen 3 handguns. Machined in a state-of-the-art facility, the Kragos slide features extremely precise tolerances for consistent barrel lockup and better accuracy down range. The CMC Kragos pistol slide is machined from 17-4 stainless steel, heat treated to H900 42-44RC, and then finally is coated with a Diamond-Like Carbon coating (DLC) for exceptional wear and corrosion resistance. This DLC coating combines an incredibly low coefficient of friction and high hardness perfect for high wear applications like on a pistol slide.Note: Channel liner not includedFeatures:Fits GEN3 Glock 19 Pistol Frames & Components45-Degree Chamfer on either Edge to Ease Holster Ingress and EgressMachined from Corrosion Resistant 17-4 Stainless Steel BilletHeat Treated to H900 42-44RCPrecision Wire EDM Breach FaceWear Resistant Black Diamond-Like-Carbon (DLC) CoatingPreinstalled Tritium Night Sights on factory Glock Front/Rear CutsAccepts Factory and Aftermarket Barrels and PartsPre-Cut RMR Footprint Mounting Slot Fits Trijicon, SOUSA RAIDRPD & Holosun HE508T, HS507C, HS407C
