Technical Specifications & Platform Features
Key Advantages of the Glock 21 Gen 5 MOS FS
Glock upgraded its iconic .45 ACP handgun to give shooters smoother handling, better ergonomics, and rapid optic integration.
1. Modular Optic System (MOS) & Front Serrations (FS)
Mounting your favorite reflex red dot sight is fast and direct. The factory MOS slide cut accepts popular red dot adapter plates without requiring custom gunsmith milling. Additionally, factory Front Serrations provide a tactile grip surface for fast press-checks and positive slide manipulations under pressure.
2. Match-Grade Glock Marksman Barrel (GMB)
Accuracy receives a major boost thanks to the Gen 5 Glock Marksman Barrel. Featuring enhanced polygonal rifling and a revised barrel crown, the GMB delivers tighter shot groupings and consistent bullet velocity out of the box.
3. Fully Ambidextrous Controls & Custom Grip Fit
The Gen 5 frame removes finger grooves, allowing a natural, comfortable hand placement for all hand sizes. Furthermore, an ambidextrous slide stop lever and reversible magazine catch make operating the pistol seamless for both right-handed and left-handed shooters.
