Shop-assembled Glock 19 Gen 3 RMR-cut slide built and function-tested in our Florida shop. Stiffler Manufacturing Speed profile stripped slide, your choice of full-length 9mm drop-in barrel, and tall (suppressor-height) sights for red-dot co-witness — drop-in fit with no gunsmithing required. An open top window shows the barrel through the slide and sits over the gas ports on the ported barrels, so ported gas vents up through the slide.

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

Features:

• Machined from heat-treated 17-4 PH stainless bar stock — tougher than the 416 stainless commonly used for pistol slides
• Stiffler Manufacturing Speed RMR stripped slide, black
• RMR-footprint optic cut with cover plate installed — fits Trijicon RMR / SRO and compatible red dots (Holosun 407C / 507C and similar)
• Open top window — shows the barrel, and vents the gas ports on the ported barrel options
• 3CR Tactical slide completion kit pre-installed — firing pin, extractor, plunger assembly, recoil rod, cover plate
• Full-length 9mm drop-in barrel (choose above): black nitride, black nitride ported, Oil Slick PVD (iridescent multi-color), Oil Slick PVD ported, polished stainless steel, or gold TiN (titanium nitride)
• Tall (suppressor-height) sights pre-installed — co-witness with most RMR-footprint red dots
• Fully assembled and function-tested in our Florida shop

Finish note: The Oil Slick PVD and TiN gold barrel finishes are decorative coatings. Like all PVD/TiN coatings, they can show wear at points of metal-to-metal contact (such as the barrel hood and locking lugs where the barrel meets the slide) over time with use. This is normal and does not affect reliability or function. The black nitride and polished stainless barrels do not show this coating wear; expect natural carbon and brass marking from use.

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.
