Sear not catching bolt?

[personman]

Hey people, I need help. My mag spews out gas randomly and it spits out half my tank. I dont think the sear is catching on the bolt.. sometimes I think I dont let the trigger go out all the way and this happens
Does this make sense? Is there somtihng else that could be happening that im not aware of?
And if this doesnt make sense, is there anything i could buy to stop the spewing of the gas? Its evil, this spewing is.. i cant stop it without unscrewing the nitro tank (this happened with co2 also)

this sounds like you are shortstroking the trigger, practice shooting without paint to get used to the trigger

yeah thats what i thought it was.. i just wanted to make sure it wasnt somthing else. i just went paintballing and the spewing crap diddnt happen.. but i think i learned how to tell when its about to spew.. i can sorta hear it.. damn i love my mag..
