gas pistol magazine problems
 

ok the mags in both my KWA g17 and 1911 tactical master have problems in which the gas will only go for a second into the mag when i charge it and then it only fires like 2 shots then its out of gas and i assure that neither one has a leak, what is the problem here?

is it venting in between shots or at the end when it stops shooting?

Are you using propane or duster?

Is your propane or duster tank full? Try using a new one.
