This is a fully assembled slide for a Glock 19 Gen3, featuring a radius cut and a threaded barrel, finished in a durable black nitride. It’s for builders who want a complete, ready-to-install upper assembly with suppressor-height sights and enhanced aesthetics. Since we started stocking it in fall 2025, it’s become one of our steady sellers in the slide category.
Stand-Out Features
- Fully Assembled & Ready: Comes complete with barrel, recoil spring assembly, and suppressor-height sights. Install it on your compatible frame and you’re ready to function check.
- Black Nitride Finish: Provides excellent corrosion resistance and a durable, low-glack black surface that’s easy to maintain.
- Radius (RMR) Cut: The slide is pre-cut for popular micro red dot optics (like the Trijicon RMR footprint), offering a clean, integrated look without needing separate machining.
- Threaded Barrel: The included barrel is threaded (typically 1/2×28), allowing for the direct attachment of a compensator or suppressor (subject to NFA regulations).
- Enhanced Sights: Factory-installed suppressor-height sights provide a clear co-witness through your optic.

Your Questions Answered
Is this compatible with a Polymer80 PF940C frame?
Yes. This slide is designed for Glock 19 Gen3 spec, which is the standard compatibility for the Polymer80 PF940C frame. It should fit and function properly after your frame build is complete and within spec.
What’s included in the box?
You receive the complete slide assembly: the radius-cut slide, a threaded barrel, a recoil spring assembly, and installed suppressor-height sights. The product itself is perfect, though we note the manufacturer’s packaging is a simple, flimsy box.
Does this work with a standard Glock 19 Gen3?
Absolutely. This is a direct replacement slide for an OEM Glock 19 Gen3. It will function on a factory Glock frame, provided you use the correct generation (Gen3) recoil spring assembly, which is included.
