Fits Glock 19 Gen 3 OEM frames and Polymer80 PF940C aftermarket frames. This assembled upper ships function-checked and ready to mount on any completed Gen 3 lower — pick your 9mm barrel from the drop-down before you check out.

The slide wears a hard black DLC (diamond-like carbon) finish for wear and corrosion resistance. A Trijicon RMR optic cut sits on top with the cover plate installed, and suppressor-height polymer iron sights ride the dovetails so you can co-witness an optic or run irons alone.

What's installed:

• 3CR Tactical Glock 19 slide with black DLC finish
• Trijicon RMR optic cut with cover plate
• Suppressor-height polymer iron sights
• 3CR Tactical slide completion kit (channel liner, firing pin, extractor, springs, internals)
• Your choice of 9mm barrel from the drop-down

What you still need:

• Completed Glock 19 Gen 3 lower (frame, trigger assembly, magazine)
• Optic of choice if running the RMR footprint

Expect a 100-200 round break-in as the slide rails fully seat against the frame. Verify fitment on a Glock 19 Gen 3 or PF940C before ordering — Gen 4 and Gen 5 slides use a different profile.
