KSC Glock 18 - gun gets a bit venty on full auto

[dave38x]

Evening chaps,

So I've been restoring my KSC G18 to full health after a year of mistreatment (mostly due to me breaking my arm, then getting married, and starting full time work - kinda ran out of time to do the important things :P )

I've fully cleaned and sorted it out, and it works perfectly on semi auto - absolutely flawlessly.

However, when blazing away on full auto one of the mags gets very venty, almost instantly, and the other doesnt.

Anyone have any idea why?

Could it possibly be because the o-rings are damaged in the magazine?

Found out my problem - repeated the test tonight, established one mag had propane in it and one mag had a mix of propane and propene - hence not getting so gassy! (I should mention the room the guns sit in is currently at around 10C)
