Glock V Series Model 20 Handgun 10MM Auto 15RD Magazines 3 4 61 Ported Barrel Black Cerakote Austria

About this product

The Glock G20 V-Series MOS is a full-size, 10mm Auto pistol built in Austria with a factory optics-mounting system (MOS) cut into the slide and a Black Cerakote finish over the standard nDLC coating, shipping in this configuration with three 15-round magazines. Glock doesn't publish an official MSRP the way some manufacturers do; the price here reflects current in-stock retailer pricing gathered across a wide dealer comparison for this exact SKU family.

What does the MOS system add to a standard Glock 20?

The Modular Optic System uses a set of included mounting plates to fit various red dot footprints directly to the slide without gunsmithing, letting an owner switch optics or revert to co-witnessed iron sights depending on the plate installed. Combined with the 4.61-inch Glock Marksman Barrel — which includes porting on this specific configuration to help manage 10mm's recoil — this is one of Glock's more accessory-ready 10mm options.

Why choose 10mm Auto in a full-size Glock platform?

10mm delivers substantially more energy than 9mm or .40 S&W, making the G20 a common choice for hunters, backcountry carriers in bear country, and shooters who prioritize raw stopping power over reduced recoil and higher ammunition capacity. The tradeoff is stouter felt recoil and a narrower ammunition selection than mainstream calibers, both worth weighing against your intended use before choosing this platform.

Does the 15-round magazine capacity affect a California purchase?

Yes. California caps detachable magazines at 10 rounds for sale and possession in the state, so all three included 15-round factory magazines exceed that limit, and California also maintains its own roster of handguns cleared for retail sale. Confirm compliant magazine options and current roster status for this model directly with your FFL before ordering.

How does delivery work?

As a firearm, the G20 V-Series MOS ships to a licensed FFL dealer for pickup, not to your home address, where you'll complete a background check and the standard transfer paperwork.

At 26.63 ounces unloaded and 38.8 ounces loaded, the G20 carries meaningful heft for a polymer-frame pistol, which helps manage 10mm's recoil impulse compared to a lighter frame chambered in the same cartridge. Glock's nDLC surface treatment underneath the Black Cerakote adds corrosion resistance beyond what Cerakote alone provides, giving this configuration two layers of finish protection rather than one. For hunters and backcountry shooters who specifically want a 10mm sidearm with factory optics compatibility and porting to help manage recoil across a long day of carry and shooting, the G20 V-Series MOS remains one of the more established options in the category, backed by Glock's reputation for reliability across decades of law enforcement and civilian use.

Glock introduced the MOS system specifically in response to growing demand for red dot-equipped duty and carry pistols, and offering it on the G20 extends that flexibility to one of the platform's most powerful chamberings rather than limiting factory optics compatibility to 9mm models alone. The included mounting plate kit typically covers several of the more common red dot footprints on the market, so most popular optics can be mounted without an additional adapter purchase, though it's worth confirming your specific optic's footprint is covered by the included plates before buying a red dot separately. Three magazines in the box is also a genuine convenience for a 10mm pistol, since spare 10mm-specific Glock magazines cost more than standard 9mm magazines and having three from the start means less immediate aftermarket shopping to build out a full range or duty loadout.
