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.

1 review for NineX19 Vapor Ported Barrel & Slide Combo for Glock 19 Gen 4/5 Hybrid

  1. David M.

    This thing is sick! It’s holding great groups (I’m running 124gr subs from 2-50 yards). Recoil is less than normal and it’s a little more flat shooting than previously was, I’m sure with hotter loads it would be even more noticeable. Only thing I can say to be cautious about is the chamber dimensions seem tighter than your loose factory glock barrel so if you roll your own you may need to undersized your brass. 100% worth buying in my opinion!
