A ready-to-run upper slide assembled in-house by 3CR Tactical for the Glock 17 Gen 3. It arrives coated, cut, and built with the barrel and tall sights installed — drop it onto a compatible frame and you are set. The deep Olive Drab Green Cerakote pairs with a titanium nitride (TiN) gold barrel for a high-contrast two-tone build.
Build Highlights:
Optic & Cover-Plate Hardware: Glock-pattern screw sizes for reference — cover plate 6-32 × 1/3″, optic mount 6-32 × 7/16″. When installing your red dot, use the mounting kit that ships with your optic (Holosun, Trijicon, Sig, etc.) rather than generic screws.
Fitment & Break-In: Designed for Glock 17 Gen 3 frames. New slides run tight — apply lubricant and rack the slide 200–300 times before live fire. Verify fitment before range use.
TiN and PVD barrel coatings wear over time at points of metal-to-metal contact, such as the barrel hood and locking lugs. This is normal and does not affect function.
