mine doesn't either...
and don't get a 5 gram. Try not to even get a 25 gram cause they bounce like a mother ****er.. If i was you, i'd go to
www.paintballkingdom.com and buy an 80 gram switch from them... might even have to call Jim himself.. And if u can solder, u can install the switch. if u can't solder or suck at it... send it to PBK and they'll put an 80 gram on it for ya
