Help with hi capa discharging gas...
ok, this hi capa was shooting fine on HFC 134, but I ran out so I thought id use propane (DUMB), well it ended up shooting and blowing back very hard, but the slide only went halfway forward after I took one shot on propane, now I got some HFC 134 and went to use that, but when I pull the trigger, all the gas discharges out of the mag, so whats wrong, new o-ring ? I dunno, please help, thanks.
