During an airsoft battle with friends, I dropped my USP. The plastic body split open and several internal components fell out. I immediatly considered my gun totaled and started thinking of buying a new gun. Well money is tight so recently I put some thought into reconstructing my USP. None of the plastic parts were damaged so I thought It would be an easy job. I easily removed the slide and the hammer. I found where most of the parts belonged but just two parts have been giving me trouble.
Here is the safety bar(?). I think these two parts may go on or near the safety.

These are the two mystery parts.

I think they can go on top of each other like this

Any thoughts or suggestions are welcome. I also have two mags and one leaks. Is there anyway I can fix the mag? I have a soldering iron and a hot glue gun.(Yeah like those will work.)
Thanks a lot
