we all know CO2 kicks harder than green gas... but green gas pistols can also use BLACK gas! furthermore, there are pistols such as the CZ sp-01 Shadow that can use both CO2 and gas mags, thus the internals must be strong enough for black gas at room temperature (i assume)
so, I would like to compare CO2 and BLACK gas (such as Nuprol 4.0):
1) which kicks harder at room temperature?
2) which has a higher fps?
3) which is better in the winter?
4) which is cheaper in the long run?
5) if you were about to buy a pistol that had both CO2 and gas mags, which would you buy and why?
thanks a lot all
