The Brownells Front Cut Slides for Glock® pistols allows any operator to build a custom Glock® style pistol from the ground up with a slide already customized with front slide serrations.The Front Cut Slides feature a unique wraparound slide serration design that aids in weapon manipulation, especially when checking the chamber. Serrations are cut to the same depth as Glock® factory models to ensure lower slide rigidity. Models are also available with top window cutout between the front serrations. Slides start out as 17-4 stainless steel billet and are machined internally to factory specifications. Slides are compatible with any standard Gen 3 Glock® 17, 19 or 26 components. The factory Glock® rear sight dovetail is machined, with a standard Glock® front sight cut at the front.
