Keep your sidearm running at peak performance with the SIG Sauer ProForce Spare Magazine for the P320 M17 MHS Gas Blowback Pistol. Designed to match the durability, realism, and reliability of the officially licensed M17 airsoft platform, this CO2-powered magazine is the ideal upgrade or replacement for players who demand consistent performance on the field.

Built by VFC under official SIG Sauer licensing, this spare magazine is engineered to exacting standards for fit, finish, and function—making it a must-have accessory for competitive play, training simulations, or extended skirmishes.

Authentic Construction & Duty-Grade Feel

The ProForce M17 spare magazine features a robust metal alloy construction that delivers realistic weight and balance, closely mirroring the feel of the real firearm magazine. This added mass not only enhances realism but also improves durability during reloads, drops, and regular field use.

Finished in a tan color to match the military-inspired M17 MHS platform, the magazine integrates seamlessly with your pistol’s aesthetics, preserving the authentic service-weapon look that SIG Sauer is known for.

CO2 Powered for Consistent Performance

Designed specifically for 12g CO2 cartridges, this magazine provides strong, consistent gas output shot after shot. CO2 power is favored by many players for its reliability in a wide range of temperatures, making this magazine especially useful for outdoor play and colder environments where green gas performance may decline.

The stable pressure delivery ensures crisp blowback action, reliable cycling, and consistent FPS, helping maintain accuracy and responsiveness during fast-paced engagements.

Field-Ready Capacity

With a 21-round capacity, this spare magazine closely replicates real-world magazine limits while offering ample firepower for airsoft skirmishes and training drills. Carrying additional magazines allows for faster reloads, improved realism, and uninterrupted gameplay—especially in milsim or competitive environments where reload discipline matters.

Whether you’re running drills, participating in events, or simply want fewer pauses during games, having spare M17 magazines on hand keeps you mission-ready.

Perfect Fit for SIG ProForce P320 M17

This magazine is purpose-built for the SIG Sauer ProForce P320 M17 MHS Gas Blowback Airsoft Pistol. Precision manufacturing ensures smooth insertion, secure lock-up, and reliable feeding when used with compatible M17 GBB pistols.

As an OEM VFC product, it meets the same quality standards as the original magazine included with the pistol, making it an ideal direct replacement or expansion option.

Essential Upgrade for Serious Players

Spare magazines are one of the most important accessories for any gas blowback pistol user. This ProForce CO2 magazine allows players to stay aggressive, maintain realism, and reduce downtime during reloads. It’s equally suited for skirmish use, training scenarios, and display or collection builds focused on authenticity.

If you rely on your M17 as a primary or secondary weapon, this spare magazine ensures you’re always prepared when the action heats up.
