Genuine Glock OEM Gen 3 slide for Glock 19 frames, factory-assembled with the Standard MOS (Modular Optic System) cut for mounting red dot optics through the corresponding MOS adapter plate. Ships with factory internals and sights installed — drop in your barrel, recoil assembly, and chosen optic plate to complete the build.
Fit and Compatibility:
What's Pre-Installed:
Not Included: 9mm barrel, recoil spring assembly, and MOS adapter plate (select the plate that matches your optic's footprint — RMR, Holosun 507C, DeltaPoint Pro, or Vortex Venom).
Break-In: Genuine Glock slides arrive lightly oiled. Apply additional lubricant to the rails before assembling onto your frame. After installing the barrel and recoil assembly, hand-cycle the slide 50 times to verify smooth lockup and barrel hood timing before live-fire.
