KJW Full Metal M9A1 CO2 Gas Blowback Airsoft Pistol, Two-Tone

Most players carry a sidearm for one reason: when the primary runs dry, or when the rules limit rifle velocity. The KJW M9A1 CO2 is built for that slot—a full-metal gas blowback pistol that delivers real recoil feedback without the cold-weather drop you get from green gas. At 340 FPS on 0.20g BBs, it clears typical indoor caps and sits comfortably at outdoor pistol limits.

Why CO2 matters. This pistol runs on 12g CO2 cartridges instead of green gas. CO2 operates at higher pressure, which means more consistent velocity when the temperature drops. Green gas can lose power in cold weather; CO2 doesn't. The trade-off is that CO2 cartridges are consumable—you'll need to stock them—and the higher pressure puts more stress on seals over time. A little silicone oil on the valve seals keeps leaks at bay.

The M9 platform advantage. Inside follows Tokyo Marui M9 specifications, which is the compatibility standard for M9-pattern parts. The magazine accepts KJW, WE, Tokyo Marui, and similar M9 Series magazines. That means spares aren't proprietary or hard to find. The 25-round drop-free magazine that ships with the gun is standard capacity for this platform.

Externals and controls. Full metal slide and frame with polymer grips keep the weight up without being excessive. A functional slide lock holds the slide open after the last round, and the manual safety sits on the frame where an M9 user expects it.

What you need to know. This is a sidearm. It's not a primary rifle replacement, and it's not built for trading shots beyond 50 feet. The blowback system consumes more gas per shot than a non-blowback pistol, so plan on fewer shots per cartridge. You'll need to buy 12g CO2 cartridges separately—they're not included.

Includes federally mandated blaze orange muzzle tip.
