Co2 mags

[Joe142]

So I recently brought a WE M9 which came with a green gas mag, being fairly new to GBB pistols and airsoft in general I was wondering if I'm able to use a co2 mag (with the 12g cartridge) in this gun or if it will do more damage than good?

My brother just bought the same. I quite like it. If there is a CO2 mag then it may take it over site limits as it already fires at 310fps. CO2 usually shoots hotter than green gas.

Ah right okay, so it has the ability to be able to shoot a co2 mag it just may be too hot for some sites? 

 

[warlord]

Apparently so
