I've done a little bit of trouble shooting and I know that the battery, motor and wiring is all in working order. Also, I'm no expert, but it looks like all the gearbox parts are ok and in the right place.
Here's the problem: I have the entire gun assembled, the battery plugged in, and the chords attached to the motor. But I don't have the pinion gear (is that what it's called?) going into the gearbox, so the motor is still loose in the grip. I put the gun on semi and pull the trigger. The motor turns on. Good. So I push the motor into the gearbox and screw on the plate at the bottom of the grip. When I pull the trigger, nothing moves and I hear no sound. Also, there is friction at the end of the trigger pull that isn't there when the motor is loose.
Anyone know what could be wrong?

With the motor installed and pulling on the trigger results in no noise. This means that something is jammed. As the previous poster said, you may have the motor pushed up too high.
If that is not the case, then there is something jammed inside your motor. You said " looks like all the gearbox parts are ok and in the right place", does this mean that you took the gear box apart? When you put the mechbox shell together, did you have to push down hard to get a side to close? If so, then the piston or tappet plate may not be in the right position. I've had this happen to me a few times, as I'm pushing the spring in, the piston moves up slightly and sometimes the tappet plate as well, then when I put the shell together, the piston or tappet plate are not in the appropriate slots.
If the tappet plate is not in the right spot (jammed), then you won't be able to push the nozzle in and have it rebound out.
