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. A polished stainless 9mm crown-cut barrel for Glock 19 Gen 1–5 is installed at the factory, along with the full 3CR Tactical slide completion kit and recoil rod.

What’s installed:

• Bullnose melonite Glock 19 slide — front and rear serrations, RMR cut with bosses
• Polished 9mm crown-cut barrel for Glock 19 Gen 1–5
• 3CR Tactical slide completion kit with recoil rod
• Suppressor-height polymer sights pre-installed

What you still need:

• RMR-footprint optic (cover plate ships if running irons)
• Completed Glock 19 Gen 3 lower (frame, trigger group, magazine)

Lubricate the slide rails before first range session. Plan on 200 rounds of factory 115gr or 124gr ammunition to fully break in the action — the polished barrel will show light wear at the lugs as it beds, which is normal. Confirm your frame is Gen 3 or PF940C before mounting.
