so i've been borrowing a friend's omega for a bit now, and i love it (i'm actually gonna buy it from her, i think). there's just a slight issue now: i took it apart to clean (it was kinda yucky in there) and when putting it back together, i've noticed that the center pin has quite a lot of play (disassembled, if i hold just the pin and it's little collar, the pin will fall right out. reassembled, the pin still moves a bit when i flip the whole top part over (from looking down at it to looking up at it, if that makes sense.) when i reassemble per the video, and go to reattach it, my atty fires constantly. i squeezed the bottom spring down a bit, to give my battery some breathing room, but it would still fire if i wiggled it a bit. looking in some threads here, i found chad's advice to stick a credit card between the slide assembly and the outer headpiece, and it seems to be working good again now. the question i have is this: why is my pin so loose (to necessitate the use of the card, etc)? it's still a great device, mostly just wondering
