Broken Icon-E

[trains are bad]

I have an Icon-E that works, except the solenoid doesn't have enough strength to trip the sear. It works, all the modes work, it goes 'clickclickclick' but like I said it won't trip the sear. I tried a new 9volt battery, that's what they take right? When I got it the grip screw was overtightened, jamming the sear in place. This thing feels awesome if it only worked...

It's not AGD; I don't know if that's cool...
