The Vapor Ported Barrel & Slide Combo from NineX19 is the ultimate upgrade for your Gen 3 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.

5 reviews for NineX19 Vapor Ported Barrel & Slide Combo for Glock 19 Gen 3

    I bought this slide the first day they were released and wasn’t sure how I would like it. After putting it together and going to the range I thought I might have issues with it cycling on a new p80 serialized frame but I was wrong. This combo worked flawless and I have about 200 on it so far. As far as recoil this is probably one of the flattest shooting slides I have ever felt and I have tried several. I would not hesitate on recommending buying one.

    This slide is awesome! I purchased the battleworn slide last year and I absolutely love it. Not only does it look badass, it has really great recoil reduction compared to my other g19 builds (that aren’t ported) My only complaint was about the front sight. About the 2nd time shot the firearm, I was about 5 shots in and the front sight fell off completely. I was lucky to find it to be honest. With a little locktight my sight is back on the slide for good. Other than that issue I am one happy owner of this slide & barrel combo.

    I bought one FDE and one Battle Worn Gray.. These slides are amazing and well worth the price! I would recommend this slide to anyone who is looking for an awesome looking slide and barrel combo that out performs any other slide setup out there!!

    Amazing slide and barrel combo. Bought this for a P80 build and it fit perfectly. I haven’t gotten to shoot live ammo through it yet but that’s coming up soon. The optic cut is very tight and holds my RMR very securely. The included RMR screws are a perfect fit as well.

    The fit/finish is great which I would expect at this price point. I love that it has the rear site forward of the optic. The battle worn finish is great as well. I would definitely buy again.

    If you’re looking for something with class that’s beautiful and functional, you needn’t look any further than this.
