I've had an umarex p08 for a while and it's an absolutely beautiful reproduction but recently I've run into a rather large problem. Every time I load a new magazine it fires the first few shots regularly but then after that the hammer stays up and all of the C02 in the cartridge fires out of the barrel in a grand spray of fog. Just 30 minutes ago it threw a gasket, I'm not sure where it came from and performance still seems to be the same but I'm sure it's not helping my problem. Any information or help on the subject would be greatly appreciated.
