Here are two reasons why you do NOT want to leave C02 in an air pistol. The constant pressure on the seals will eventually cause them to distort and leak. If someone else picks up the pistol they can discharge it accidentally. For the few cents it cost for a new C02 powerlett it is not worth keeping it in the pistol. I leave my Co2 guns charged with Co2 all the time. According to Tim @ Mac1 airguns, he told me to leave it charged with gas. Reason being is that it keeps the seals seated and and valve clear of debris and dust. It will also tell you if your gun has a leak the next time you shoot the gun. If the Co2 is gone, you know you have a leak.
If you are asking about the Crosman C02 pellet pistol then Yes that is what it is designed to power the pistol.
You cant, the CO2 that is in the marker is vented out when you take the tank off.
No.
