A torque screwdriver and a good set of driver bits are worth their weight in gold. Using a good fitting bit and proper torque is the best way to avoid snapped, buggered, and stripped-out screws.
Along with glue, another fix is to install threaded brass rods (called stock repair pins) that will hold and bind the two pieces together. Not as good as the pros will do it, but would be a workable solution to make the stock functional.
Wow, and I thought that I had some crazy exes. Id consider losing the gun getting taken by the police a bargain compared to what else you could have lost that day (your life).
