Hi, I'm Sanin and I've been playing for quite a few years but I don't have much knowledge about gas blowbacks. I've owned a few and I recently got the ASG CZ-P09 C02 and am having issues.
When I load a full gas, full bb magazine the gun will shoot normally for a couple shots then it will start losing power and the bbs will drop very quickly and the blowback action is slow and it feels as if I don't have much gas in the magazine. The gun will then spurt out all the remaining gas and leave it empty. Earlier today I lubed up the gun and attempted shooting it, same results except that it was spurting out gas and I emptied out the bbs and the slide held open. I started to dry fire and the power came back and the gun was shooting strong. I think that the bbs may have something to do with the performance, please help if you know anything.
