I am using the Dawson Charger set on mine and really like the sight picture. This photo is from face distance with arm fully extended and represents the real sight picture.
The corners of the rear sight are nicely beveled and rounded. They don't dig into my ribs or cut my shirts like my Ameriglo Defoors on my Glock 19.
Here is a 10 shot, 25 yd. group off the bench with my handloads. The group is centered about four inches high at that distance. I need to adjust the windage.
Another 5 shot, 25 yd. group (offhand) with Fed. 147 HST was also about four inches high.
