The gun is pretty straight-forward and the only tricky part I've found has to do with the safety. (Another shooter on THIS forum tipped me off and gave instructions.)
There is a small coiled spring inside the safety lever on the gun, and if you get that accidentally apart, there's he** to pay getting it back together.
Using a paper clip or small piece of wire insert the end of the clip/wire into the small hole on the safety, and move it around until it engages a second hole/detent inside the unit.
You can then remove the safety without problem.
You'll want to be sure the pin stays in place while the safety is set aside (as you diassemble the rest of the gun).
