The SIG Sauer ProForce P320 M17 Co2 Magazine is an official factory-original (OEM) feeding system engineered specifically for the SIG Sauer ProForce M17 Gas Blowback (GBB) airsoft training pistol series. Manufactured to strict SIG AIR specifications by VFC, this heavy-duty magazine integrates a specialized high-pressure internal gas reservoir directly within its structural chassis. This engineering layout delivers maximum pneumatic efficiency and consistency, providing a crisp, hard-kicking blowback response that perfectly matches the operational cycle of the military-contract sidearm.
