Should I get a green gas or CO2 powered blowback airsoft pistol.
If you live in a cold climate CO2 pistols maybe the way to go. Green gas pistols performs the best in warmer climates or indoors.
The reason green gas guns are less efficient during the winter or colder climates is to do with the “vapour pressure” of the gas. Due to being under high pressure, the airsoft gas you put in a magazine is in a liquid state. When you fill the magazine you’re filling it with the liquid “gas” until the pressures in the bottle and the magazine become equal. Now, you have liquid in your magazine and the liquid evaporates to fill any space left in the magazine with gas.
