NineX19 X1 Slide – RMR Cut for Glock 19 Gen 3
$319.00
Lightweight, RMR-cut X1 slide for Glock 19 Gen 3 pistols and compatible Glock 19-pattern frames. CNC machined in the USA from 17-4 stainless steel and supplied with a matching optic cover plate.
The NineX19 X1 Slide for Glock 19 Gen 3 combines reduced reciprocating weight, aggressive styling, and practical performance features in a direct-replacement Glock 19-length slide.
Large machining windows reduce slide mass and expose the barrel while helping heat escape during extended shooting sessions. Deep rear serrations provide a secure gripping surface for slide manipulation, and the direct RMR-pattern optic cut allows compatible red-dot sights to mount without an adapter plate.
Each X1 slide is CNC machined in the USA from 17-4 stainless steel and finished in Black Nitride, FDE Cerakote, or SIG Dark Gray Cerakote.

Glock 19 Gen 3 Compatibility
This slide is designed around the Glock 19 Gen 3 slide and recoil-system pattern. It is compatible with factory Glock 19 Gen 3 frames and many aftermarket frames designed to accept a Glock 19 Gen 3 upper.
Compatible platforms may include:
- Glock 19 Gen 3
- Ruger RXM frames configured for a Glock 19-length Gen 3 slide
- Compatible Polymer80 compact frames
- Compatible Nomad Defense frames
- Other frames specifically designed for Glock 19 Gen 3 slide assemblies
This slide should not be purchased as a direct replacement for a Glock 19 Gen 4 or Gen 5 slide. Frame conversions may require additional components or modifications and are outside the slide’s standard fitment.
Which Optics Fit the X1 Slide?
The X1 slide has a direct RMR-pattern optic cut. Compatible optics include the Trijicon RMR and other sights manufactured for the same mounting footprint, such as select Holosun 407C, 507C, and 507 Comp models.
Always confirm the optic manufacturer’s stated footprint before installation. Optics using the RMSc, ACRO, DeltaPoint Pro, or other mounting patterns will require a compatible adapter solution and are not direct-mount optics for this slide.
What Is Included?

- Matching RMR-cut cover plate
This is a stripped slide. The barrel, recoil spring assembly, internal slide parts, sights, and optic are not included unless specifically selected or stated elsewhere on the product page.
Installation and Function Testing
Complete the slide using components intended for the Glock 19 Gen 3 upper system. Verify extractor operation, firing-pin safety function, barrel lockup, recoil-spring fitment, and unrestricted slide movement after assembly.
Safely function-test the completed pistol before using it for competition, carry, or defensive purposes.

Order arrived super fast and the quality on this slide is second to none.
Couldn’t find one thing to complain about even if I try, if you need a slide and have a chance to grab one pull the trigger and you won’t regret it.
Miguel Sanchez (verified owner) –
Delivery time was fast and the quality is much better than I expected. I ordered the FDE color and it’s VERY close to the FDE as the p80 frame, especially when compared to a G19X.
For price, design, and Included optic cut this has to be by far one of the best slides to go with.
Trevor Moran (store manager) –
Completed my FDE build with this slide and it matches the steel city trigger and magwell nicely. This slide racks smoother than my original glock slide and shoots well, I’d say recoil has been reduced.
