I felt this way too, but they are rugged, and even with rough handling the poi doesn't shift and there are so few parts it's refreshing at this point.
To your point on stamped steel I would add plastic to that list too. There is no reason to have not improved on this.
As for the trigger, I had removed that auto safety cocking piece already and just today my trigger would not fire for some reason. I re-engaged the safety and then disengaged it and the gun fired. I was not t f happy about that! My milage isn't going to vary too much, I'm taking this thing apart and fixing it right. I am getting rid of the other thing that bothers me and that is the pins they use. You just would not believe how much I hate those kind of pins. I am through bolting those parts. When I want to take apart a gun, I want to do just that, I don't want to be swinging a hammer at it. Plus every time you take those out you are beating up the gun, just plain stupid. You should be able to work on your gun repeatedly without damaging anything.
I still think that it is a little beast though. The power that it puts out for its size, the simplicity, the toughness, it is worth my time to make it right.
