Zev Technologies Slide is designed with tighter tolerances to increase accuracy and performance. The Orion features a stylish pattern which provides an all-over non-slip grip. Rounded edged serrations are not overly aggressive and easy on the un-gloved hand. It is manufactured from a single billet of 17-4 stainless steel to tighter tolerances than factory slides for increased consistency in barrel lockup which improves accuracy. The Orion utilizes a patented optic cut and a lowered ejection port to aid in ejection of brass. Included is a RMR adapter plate. This model is compatible with Glock 17 Gen5 and has a titanium gray finish.
