The Vapor Ported Barrel & Slide Combo from NineX19 is the ultimate upgrade for your Gen 4 or 5 Glock 19 build. The matched porting on the Vapor barrel and slide provide a significant reduction in felt recoil and muzzle rise, splitting the gases around the sight line of the slide and allowing for faster follow-up shots.

NOTE: The Vapor slide is designed with a combat-cut sight configuration. This optimizes the slide for use with a red dot optic, providing a clearer sight picture through the back of the optic with minimal obstruction. The slide is intended to have a red dot installed as the primary sighting system, with the iron sights providing a functional backup in the event of an optic failure. Because this slide is specifically designed to be used with a dot, we do not include – or even manufacture – a dedicated cover plate for the optic mount.
