Based on our "Front Cut" slide we designed originally for the Glock G43, this RMRcc Cut Slide includes serrations at the front and rear of the slide for easy manipulation, which is a big help when you're fighting against the stiff recoil spring inside this compact 9mm. Just behind the ejection port, though, you'll see a cutout that's tailor-made to accept the Trijicon RMRcc red-dot sight. When you're not using a red-dot sight, the slide includes a cover plate with a dovetail designed to accept all standard Glock rear sights, and a slot at the front of the slide is compatible with Glock's front-sight tenon.
