Really good stuff, DD.
NitroX- yes, that butt plate would be ANYTHING but comfortable to shoot.
The hooks are bad enough, but being rounded side to side, narrows the contact surface as well. That is not a good feature.
The hooks means it has to be held in the shoulder/arm pocket. The top hook will bite with a chunky person shooting it. The lower hook will be in the pit. If held out on the arm, terrible pain, as well as if held in the shoulder/pectoral pocket.
