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 suppressor-height sights installed — drop it onto a compatible frame and you are set. The deep Olive Drab Green Cerakote pairs with a PVD Multicolor “Oil Slick” barrel for a finish that stands apart.
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.
PVD barrel coatings wear over time at points of metal-to-metal contact. This is normal and does not affect function.
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.
Kit fitment — the frame parts kit is Gen 3: the trigger housing ships with the Gen 3 ejector. The slide itself fits Glock 17 Gen 3 frames.
What you'll still need to supply
This is a slide assembly and a frame parts kit. It is not a complete pistol and does not include a frame.
