OT:
The Bug is very fragile, nothing like TAC-2.
My first one broke down with exactly the problem you described plus one of the fire-buttons stopped working.
It´s great for speed and accuracy tough. And the grip means that to fire with the right thumb is a really effortless move, no nintendo-thumb.:-D
And its hard to by secondhand, either it´s broken or close to it or your lucky and its like new because the former owner disliked the design.
