I don't have any problem with properly designed guns. As I have said before, when someone shows me a new gun, the first thing I ask about is the safety mechanisms and how to load and unload it. Looking through that manual, it has a some nice safety features built into it. The trigger pull step in the disassembly looks like a brain fart by more than one person - the designer and whoever reviewed it up the chain.
While searching for this yesterday, I found a forum where there was some discussion of how to feel safe while handling this gun. One poster recommended buying a large planter pot and filling it with sand to use as a "target" while taking the gun apart. Put it in the corner of a room and put a fake plant in it so the wife won't complain.
