Years back, you could put on a Bo-Mar rear sight, but you needed to raise the front sight.
I had the front sight raised on the 41 by cutting the sight off and dovetailing a slot in for a taller front sight. I used that gun for Bullseye.
The 52 was shot with a deep sub 6 hold on the target, using the original front sight. I used this gun for International Centerfire.
