I've owned a KWA glock 19 for over a year and always emptyed the gas out after use.. never has a leak problem with it. I plan on doing the same with my WA mags.

I believe it basicly comes down to this.. you decided if you wanna keep gas in it or not both work the same to me.

Unless someone can sciencetifically discribe how keeping gas in the mag helps and how leaving it empty is bad or other way around.
