ianfroese,
Don't worry, there is very little you can do to the gun( unless you try) that someone else can't fix. Just be sure screwdrivers fit the slots, even if you have to re-grind/file them to fit. Remember: pins go in right to left and come out left to right, and screws are likely marked as to which side they go in( a line filed on the end is for one side, no line is the other side, if there are 3 identical screws the odd one will likely have a X). Different people might use different systems, so look at the ends when you take the first ones out. If you put them back in the wrong place, the slots won't line up and engraving won't match up. Dovetails go in and out the same as pins. Good luck.
Mike
