The Vapor Ported Barrel & Slide Combo from NineX19 is the ultimate upgrade for your full-size Gen 3 Glock 17 or Polymer 80 build. The matched porting on the Vapor barrel and slide provide a significant reduction in felt recoil and muzzle rise, allowing for faster follow-up shots while splitting the gases around the sight line of your optic.

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. Warner C.

    Bought this specifically for the battleworn gray finish and the look and fitment is spot on, emailed you guys some pics to use. Shout out to Dave at ninex for letting me get a hands on with his own gun at a match.

  2. (verified owner)

    Purchased the Gold barrel with black slide. Absolutely Beautiful. I would have given it a 5/5 but the portion of the slide that interacted with the slide release on my glock 17 needed just a little bit of sanding. Other than that I absolutely love it and would def buy another barrel/slide combo.
