Hey guys, simple q here, i have a proto slg 09 here but i don't like how un sensitive the trigger is so what size allen key do i need to adjust it? as none of mine fit, also i don't have the manual and can't find one online, also on a side note, how well sealed is the grip frame supposed to be to the main body, because mine has at some points in it space effectively, more aesthetic than anything but hey, if not how can i fix (the screws are quite tight)
thanks
thanks
