Mr. 16 gauge,
Right you are- ADJUSTABLE sights because wadcutters and JHPs impact at different points. Back in the mid-1980s my agency went from 158 lead SWC hollowpoints to the then-fad 110 JHPs for our 2 and 4 inch fixed sights M-10 S&W revolvers. At our fist semi-annual qualifications with the 110s, 55 out of 94 agents failed to qualify. I know because I was the Firearms Coordinator (Instructor). I put my 2-inch M-10 in a Ransom Rest and showed the Regional Chief how the lead 158 were in the Bullseye at 25 yards and the 110s were 7 inches lower and 4 inches Left.
I wrote a Special Report describing the shift in point of impact from point of aim. My supervisor let my report go to National Headquarters with his endorsement: "I do not think this is a serious problem and it can be corrected through training at semi-annual qualification." When questioned, he said, "Tell the agents to aim high and right." Duh!
Adam
