Assembled Glock 19 Gen 3 slide — Mercury Precision Zoom RMR-cut, shop-built at 3CR Tactical. The black Cerakote Zoom slide is paired with a Oil Slick (PVD Multicolor) 9mm barrel and Standard-height polymer sights (front white dot) — ready to drop onto a Gen 3-pattern frame.
What is installed:
Fitment: Glock 19 Gen 3 and compatible Gen 3-pattern frames (SCT, Grit, Dagger, and similar). No fitting required — drop onto the frame, cycle to verify function, and go.
Optic & cover-plate hardware: RMR footprint. Cover-plate screws are 6-32 × 1/3"; optic-mount screws are 6-32 × 7/16". When installing a red dot, use the mounting kit that ships with your optic rather than generic screws.
Care & break-in: Each slide is function-tested before shipping and will need lubricant and a normal break-in period. The Oil Slick PVD finish is unique to every barrel and will show contact wear over time — normal and cosmetic; treat the barrel as you would any PVD/TiN part.
Photos are representative; each slide is assembled to the specification described above.
