Sig Sauer P320-M17 CO2 Air Pistol .177 Caliber, 20+1 Rounds, 4.70" Barrel, Coyote Polymer Grips

The Sig Sauer P320-M17 CO2 air pistol brings U.S. military-grade ergonomics and controls to your airgun practice sessions without the centerfire commitment. Built as a faithful replica of the Army's standard-issue M17, this semi-automatic .177 caliber pistol delivers the handling, controls, and takedown procedure you'd encounter on the actual service weapon—ideal for shooters who want to train with realistic mechanics, dry-practice trigger transitions, or simply enjoy plinking with a gun that mirrors professional military design. The full blowback metal slide cycles with each shot for authentic recoil impulse, while the drop magazine with cam lever loads quickly between strings.

At just over 2 pounds and 8 inches overall, the M17 air pistol fits naturally in your hand thanks to its Coyote polymer grips—the same ergonomic profile as the centerfire version. The fixed sights keep the platform simple and reliable, and the M1913 accessory rail lets you mount lights or lasers for low-light work or target identification. With a 4.70" barrel and muzzle velocity up to 430 fps, you'll get respectable pellet energy for casual target work and backyard shooting.

Loading and field-stripping mirror the real M17, making this air pistol a smart training tool for shooters who own the centerfire and want to build muscle memory without the noise, recoil, or ammunition costs. One 20-round magazine is included. Whether you're a P320 owner looking for a no-cost practice alternative or an airgun enthusiast who appreciates authentic military design, the Sig Sauer P320-M17 CO2 air pistol delivers surprising realism in a compact, durable package.

Frequently Asked Questions

Can I use this to practice with my centerfire P320-M17?

Yes. The air pistol shares the same ergonomics, controls, manual safety lever, magazine release, and field-strip procedure as the military M17, making it excellent for trigger transitions, malfunction drills, and other dry-practice techniques without ammunition or noise. It's not a perfect replica of every mechanical detail, but the core handling is authentic.

What comes in the box?

The pistol and one 20-round .177 caliber pellet magazine. You'll need to supply CO2 cartridges separately for operation.

Can I add a red dot or other optic?

Yes. The M1913 Picatinny rail on top accepts standard airgun and firearm-compatible accessories, including red dots, magnifiers, and tactical lights.

Is this air pistol legal to own?
