Key Features
- Modular Optics System (MOS) Slide — Lets you mount a red dot directly without milling, so you can co-witness with factory fixed sights and cut down on gunsmith costs.
- Front Slide Serrations — Give you a positive grip surface for press checks or malfunction clears, even with wet or gloved hands.
- 10mm Auto Chambering — Delivers 10mm energy levels that outperform 9mm and .40 S&W for defensive or hunting use, while still fitting a standard frame size.
- Three 10-Round Magazines Included — Keeps you loaded for extended sessions and compliant in capacity-restricted states.
- High-Durability Polymer Frame with GLOCK Safe Action System — Provides consistent trigger pull and corrosion resistance across temperature extremes and dirt exposure.
Who It’s For
This pistol fits shooters who need a reliable 10mm for defense against large game (bear, moose) in the backcountry, or anyone who wants a full-size optic-ready handgun for competition or range training. It’s also a solid choice for law enforcement or security personnel who prefer 10mm ballistics.
Pros & Cons
- Pro: Factory optics cut saves you $100–200 over aftermarket milling.
- Pro: 10mm offers significantly higher muzzle energy than 9mm — roughly 600 ft-lbs vs 350 ft-lbs with standard loads.
- Con: The MOS mounting plate system can introduce slight height over the slide, which may require a suppressor-height front sight for absolute co-witness. Some users swap to aftermarket plates for a lower profile.
- Con: Recoil is stiffer than a 9mm G17; not ideal for shooters with weak grip strength or arthritis.

FAQ
Does the GLOCK G20 V MOS come with mounting plates for optics?
Yes, it includes the MOS plate set (typically 4–5 plates) for popular footprints like Trijicon RMR, Holosun, and Leupold. You’ll need to use the correct plate and screws per the manual.
Can I use standard 10mm ammo with this pistol?
Absolutely. The G20 V MOS is built for full-power 10mm loads, including defensive and hunting ammunition. It will also run lower-pressure 10mm loads like those from Federal or S&B without issue.

Per GLOCK specs, the barrel is 4.61 inches. That’s standard for the full-size G20, giving good velocity for 10mm rounds.
Is this pistol California-legal?
No, the G20 V MOS is not on the California Roster of Handguns Certified for Sale. It ships with 10-round magazines, but you’ll need to check your state’s roster for compliance.
