It uses a 12 gram C02 powerlett
It all depends on the C02 cartridge. If it's a small 12 oz cylinder, then the answer is NO.
Most all C02 air guns use the common 12 gram C02 cartrage.
depending on the model around 70 - 90 shots
This usually happens when the C02 is running out of gas.
you screw the adapter into the gun, and then the co2 cartridge.
It is a pistol that fires BBs or Pellets that are powered by Air or C02, NOT Gunpowder. Some countries consider them Firearms some do not consider them firearms.
As soon as you release the pressure on the C02 it will loose all it's gas and will then not be able to fire the gun anymore. You must put in a new C02 powerlett to charge the gun again. The old C02 powerlett can be trashed it can not be recharged.
