The KRAGOS is manufactured in a state-of-the-art facility to tighter tolerances than factory slides for increased consistency in barrel lockup, improving accuracy. Constructed from 17-4 stainless-steel billet, CMC's KRAGOS Glock Slides are then heat-treated to H900 42-44RC and coated with a Diamond-Like-Carbon (DLC) finish for added corrosion resistance and durability. DLC coatings exhibit a desirable combination of low coefficient friction and high micro-hardness, making it extremely effective in high wear applications.The KRAGOS features a wraparound scalloped serration pattern that improves grip while manipulating the slide, like press checking the chamber or clearing a malfunction. The 45-degree chamfer edge eases holster ingress and egress, preventing snags on gear. All slides come with standard Glock sight cuts equipped with tritium night sights and pre-cut optic pocket for the easy, secure, low-profile mounting that accommodates optics that follow an RMR footprint.The KRAGOS Slide accepts factory or aftermarket barrels and parts, is the ideal upgrade for your factory Gen 3 Glock 17, Gen 4 Glock 17, or Gen 4 Glock 19 pistols and pairs nicely with Polymer 80 frames for new custom gun builds.All CMC products come with a Lifetime Warranty and are made in the U.S.A. CMC proudly designs all its products for Law Enforcement, Military, and Civilian use.FEATURES:Fits Gen 3 Glock 17, Gen 4 Glock 17, or Gen 4 Glock 1945-Degree Chamfer on Dither 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 RAID RPD & Holosun HE508T, HS507C, HS407CCMC's 100% Lifetime Warranty*Channel liner required for these slides.
