I know this is an old topic as I found
this when searching, but other than that, there was no where where the topic was being discussed. I just spent the last half hour searching this forum.
Anyway, my friends KSC G19 sprays propane everywhere when filling so its impossible to tell when its full. He was really worried about it but I knew it happened to KSC mags but had no idea how to fix it. Just got a KSC M93r (version 1) and it does the same but the thing is I cant get it to fill completly, never fires more than half the mag. Then I remembered I saw two guys with KSC glocks at a game once and when they filled their mags with propane it didnt spray. O-ring? Or something else?
