Things I liked:Power, accuracy, trigger, weight, fit in hand Things I would have changed:Rear sight adjustment changes. What others should know:Based on what I read, I was expecting maybe an O-ring problem but I had a trigger problem after 60-70 shots. Inside, the sear had a burr which caused the internal hammer to hang every 20-30 shots. I used a file to remove it, no problems after that. The sight elevation screw moves clockwise a bit with every shot, I will need to loctite it. Left bicep was hurting after doing 30 - 40 shots a day for several days to see if the gun would fail. The joint between the upper and lower parts is a little uneven. I imagine the P3 and HW40 versions maybe nicer.
