Shop-assembled Glock 19 Gen 3 RMR-cut slide built and function-tested in our Florida shop. Aggressive front and rear knurled cocking grips on a black nitride blank, a full-length 9mm black nitride barrel, and tall (suppressor-height) sights for red-dot co-witness — drop-in fit with no gunsmithing required.

Fit: Glock 19 Gen 3 frames. Will not drop on Gen 4 or Gen 5 frames.

Features:

• Knurled-grip stripped slide blank, black nitride finish — aggressive front and rear cocking grips
• RMR-footprint optic cut with cover plate — fits Trijicon RMR / SRO and compatible red dots (Holosun 407C / 507C, etc.)
• 3CR Tactical slide completion kit pre-installed (firing pin, extractor, plunger assembly, recoil rod, cover plate)
• Full-length 9mm black nitride drop-in barrel
• Tall (suppressor-height) polymer sights pre-installed — co-witness with most RMR-footprint red dots
• Fully assembled and function-tested in our Florida shop — no gunsmithing required

Optic mounting screws (not included): use the screws supplied with your optic, or 6-32 × 1/3" for the cover plate and 6-32 × 7/16" for the optic when mounting on top of the plate.

Verify Glock 19 Gen 3 frame compatibility before install. Cycle the action by hand to confirm full lockup, then run a 100–200 round break-in with quality 115–124gr FMJ before relying on the slide for duty or carry.

Frame parts kit included

This build is bundled with the 3CR Tactical frame completion kit — the lower components needed to finish a frame, bundled below what the kit sells for on its own.

• Trigger with trigger bar
• Trigger housing with ejector (Gen 3)
• Trigger spring, trigger pin and trigger housing pin
• Connector
• Magazine release with spring (G17/G19)
• Slide stop release with spring
• Slide lock with springs
• Locking block pin

Kit fitment — the frame parts kit is Gen 3: the trigger housing ships with the Gen 3 ejector. The slide itself fits Glock 19 Gen 3 frames.

What you'll still need to supply

• A Glock 19 Gen 3 frame and a magazine

This is a slide assembly and a frame parts kit. It is not a complete pistol and does not include a frame.
