Assembled Window Slide for Glock 19 Gen 3 — DLC, RMR Cut

Fits Glock 19 Gen 3 OEM frames. Ships fully assembled — completion kit, sights, and cover plate are installed and verified before it leaves our Florida shop. Drop it on your Gen 3 lower and you have a working upper minus the barrel.

The slide carries a hard-wearing diamond-like carbon (DLC) finish over a window cut at the muzzle for a lighter reciprocating mass. The top is milled to the Trijicon RMR optic footprint and ships with a cover plate so you can run irons until you mount glass.

Included and installed:

• 3CR Tactical slide completion kit (firing pin, extractor, plunger, recoil rod)
• Polymer standard-height iron sights (front and rear)
• RMR cover plate

Specifications:

• Frame compatibility: Glock 19 Gen 3 OEM frames
• Finish: hard black DLC (diamond-like carbon)
• Optic cut: Trijicon RMR footprint
• Caliber: 9mm Luger (barrel sold separately)
• Optic mounting screws: 6-32 × 7/16" recommended; cover plate uses 6-32 × 1/3" — match your optic manufacturer's screw kit

Barrel not included. New aftermarket slides require break-in: rack the slide 200–300 times dry, lubricate the rails, and confirm fitment on your specific Gen 3 frame before live fire.
