    Hey, I have GBB KWA Glock 18C and I have problem, not sure if thats normal or not, basically after dry firing 2 mags the slide covers in ice and once each mag is done it just releases gas fully from below slide giving me frostbite (frost burn) on hand if I don't wear gloves at the time. It releases last bit of gas usually. Here are pics and vid:
    (btw in end of video it fires just few shots - that's because my green gas cannister is gone, so it was just barely green gas there).

    So what could be the problem?

    Gas expands. As it expands, quite rapidly in a GBB pistol (particularly a full auto one), it freezes. This is due to the lower pressure outside the mag/can of gas - nothing to really worry about, just go easy on the pistol so the seals don't freeze dry and shít themsleves.

    Thats pretty odd, I have a meister g17 and while I could do the same ROF that your doing in the vid (which isnt excessive) it would be cold alright but no where near frosting?

    To me at least it seems like there isnt a proper seal between the mag and the nozzle meaning that per shot there is a little extra expelled gas in the system thats freezing as it expands at each shot leaving anywhere near the leak covered in frost. It would also make sense that the frost is mostly collecting near the upper rear potion of the gun.

    I assume from the vid your refilling the same mag so have you tried another mag instead?
