Grit Grips GG19 Gen 3 MOS Custom Glock 19 9mm Compact Pistol – 18+1 Optic-Ready
This GG19 Gen 3 MOS pairs Glock’s proven 19 slide assembly with a serialized Grit Grips polymer frame and a series of thoughtful performance upgrades. The result is a compact, 9 mm pistol that keeps Glock reliability while adding an 18-round capacity, an optic-ready slide, and enhanced ergonomics that matter on the range or in everyday carry.

What’s Included
- Grit Grips GG19 Gen 3 MOS 9 mm pistol
- 2 × 18-round steel magazines with high-visibility green followers
The serialized Grit Grips frame is the legal receiver and incorporates nickel-plated steel rails for durability. Its 18° grip angle, directional wrap texture, accelerator pad, and double under-cuts promote firm control without added bulk.
The matte-nitride slide carries forward and rear cocking serrations and a factory MOS cut that accepts RMR-footprint optics. Standard polymer dot-and-notch sights provide a familiar sight picture until you add an optic.
A flat-faced skeletonized trigger shortens perceived pull length, while the enlarged, reversible magazine catch and flared mag well speed reloads. Both extended 18-round magazines seat flush with the mag well for maximum capacity in a compact package.
The 4.02-inch stainless-steel barrel, striker-fired action, and Glock 19 slide assembly retain the reliability and parts compatibility shooters expect, making this a ready-to-run upgrade over a standard Gen 3.
