Dual CO2 Cartridge holder

A while back when I only played pistol with CO2 cartridges, the only place I could really carry cartridges that were easy to get to was my pocket. However, in games I would lose 1-2 cartridges due to them falling out of my pocket. This allows a pistol player that uses CO2 cartridges to carry 2 cartridges on their gun. With a simple push of the back, the cartridge is removed and can be used!
