The UNIT9 Magazine has been thoughtfully designed for maximum durability and easy re-loading. Each magazine accepts the 8g threaded CO2 cylinders and 8mm projectiles. A single 8g CO2 cylinder should provide two magazines worth of ammo, or at least 30 full-action cycles with slide lock after shot 30. 

The UNIT9 Magazine has been thoroughly tested for durability with dozens of drops from every orientation from 5 feet. When training with the UNIT9, you can hit the magazine release button with confidence and let the mag freely drop onto any surface.
