There are several factors that effect "HOW LONG" is. Temperature, How fast you pull the trigger. and how long the "powerlett" is in the pistol. It is best to say about 50 or more shots per powerlett. However never leave the C02 in the pistol when you are done. It will eventually leak out and may damage the seal if the pistol stays under pressure. Also it will prevent someone from picking up the pistol and accidentally firing it.
