dont know if anyones told you yet cheapy. but the O-ring on your pistols magazine needs to be lubed. i dont know how much you know about airsoft guns. but just take some lube.. like some 100% silicon oil. put a drop on the gas release button on the back of the magazine and push the button a few times to get the oil swished around in there and let it sit on its side so that the oil leaks deep into the valve. and just for maintenance after you did the last step, put a drop on the on the valve on the bottom of the mag too. that should fix your problem. if not, you need a replacement O-ring for your gas release valve.
