Question

What determines the amount of PSI that my paintball gun has?

Answer 1

Your gun doesnt have PSI, psi is pounds per square inch, and is used measuring gasses. Different paintball guns run off different PSI, high end guns generally run off compressed air and use about 200 psi, most lower end guns that run on Co2 use about 800-1000 psi (Co2 is only 1 pressure, you cant change that), Guns that can run on Co2 can also run on compressed air that runs around 800 psi.
