Fits Glock 19 Gen 3 OEM frames and Polymer80 PF940C aftermarket frames. The bullnose profile gives a Gen 3 frame the rounded forward look of a Gen 5 slide — same fit, updated profile.
The slide is melonite-coated with front and rear serrations and an RMR optic cut with recoil bosses for direct optic mounting. Choose the crown-cut 9mm barrel above — Oil Slick PVD, polished stainless, TiN gold or Rose Gold PVD. It is installed in our shop along with the full 3CR Tactical slide completion kit and recoil rod.
What’s installed:
What you still need: an RMR-footprint optic (cover plate ships if running irons) and a completed Glock 19 Gen 3 lower (frame, trigger group, magazine).
Available builds:
Finish note: The Oil Slick PVD, Rose Gold PVD and TiN 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 polished stainless barrel will show light wear at the lugs as it beds in, which is normal.
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.
Lubricate the slide rails before first range session. Plan on 200 rounds of factory 115gr or 124gr ammunition to fully break in the action. Confirm your frame is Gen 3 or PF940C before mounting.
