I have a Kingman Spyder Xtra. I have used it two times. But now when I plug my CO2 tank into the gun no CO2 will come out. This happened to me the other day right after I got it refilled. I just tested it today. I cocked it after putting the tank in.

you might need to fill the tank

did you cock the gun

when i first got a 9 ounce frum canadian tire my pin was stuck so no co2 could come out, so you might want to look into this.

also if it has an on/off check that it is on, and also check if it was on when they filled it, cuz then it would just pour out after it got filled

Check all the gas connections and all internal O-rings. Also check the pin valve in the tank and the tank O-rings.

ok when that happens fill the tank cock it and if that doesnt help then go have a shop look at it
