OK, went outside yesterday and affixed a one inch sticker to a paper plate, and hung it over the same target, same distance @ 12 yards.
This time did two things. I told myself to forget everything I've tried to use to improve my shooting, and just do it the was my dad taught me. Modernism be damned, we're doing it old fashioned 1950s-1960s FBI taught style.
So I squared with the target, closed my eyes, relaxed, and brought the pistol up to my normal natural point of aim, and then opened then. With no muscle tension in the arms this time I was on the plate, and it was much easier to stay on the target square.
The other thing, was after looking at how bad the sight was blurred, I took my glasses off. The front blade was crisp, and while the target square wasn't well defined, at an inch it was visible, and it seem evenly blurred ( before I focused on the sight- near sighted, bad astigmatism ).
Anyway, I only had to concentrate now on the front sight, a bit on left had pressure, and trigger pressing, since the stance was natural, though not tactically relevant.
I called one where I did break the wrist on, but the group is more than acceptable to me with this gun and my eyes.
