Glock 19X Crossover Design
The Glock 19X was developed from Glock’s submission for the U.S. Army Modular Handgun System competition. It combines:
- Glock 17 full-size frame
- Glock 19 compact slide and barrel
This gives the pistol:
- Full-length grip for better control
- Compact slide for faster handling
- Duty-size ergonomics
- Reduced muzzle weight compared with a Glock 17
MOS Optics-Ready System
The MOS (Modular Optic System) slide allows mounting of compatible red-dot optics using adapter plates.
Features:
- Factory optic-cut slide
- Interchangeable mounting plates
- Optic-ready configuration
- Maintains factory reliability without aftermarket slide milling
Common optic choices include:
- Trijicon RMR/SRO (with appropriate MOS plate)
- Holosun pistol optics
- Aimpoint ACRO-style optics (with proper adapter)
- Other compatible miniature red dots
The optic is normally sold separately unless included in a package.

Typical benefits:
