    I bought a second hand ksc/kwa glock 18 ( I won't do that again) but when I load the gun with gas in semi auto and fire, I can get about only two shots and the the gas spews out the barrel. When I switch to full auto a few shots fire but the gas comes out and the slide locks almost halfway. I think it's the magazine but this is my first gas gun!

    Thanks!

    The gas is leaking through the magazine vaulve it seems. Is the oring good? Put some gas in the magazine and leave it out for a day and see if it still has gas in it. Its always good to get another mag though.

    Probably broke the rocket valve on it. Breaks often from what I hear on KWA glocks.
