After having an Ameriglo rear drift to the edge of the dovetail on my G45 MOS during a Gabe class last September, I switched my Glocks to Heinie's MOS Ledge sights to make use of their dual set-screw rear sights. While Heinie says, "All Heinie sights are designed to “cover the target”. POA/POI" I find this to be otherwise. Here is a 25yd group with my MOS Glocks using the MOS Ledge Heinie sights; note the 6:00 on the black hold:
G45:
G19 (with a shank):
So now a couple weeks ago I got a nice classic P226 from a member here and it has Heinie Straight 8's on it. How do those hit with a 6:00 hold on the black? And guess what, 124 + P GDHP hits about another 2" higher!
P226:
I find this to be VERY aggrevating! I just want the damn sights to hit where they're supposed to. It's less of an issue on the MOS guns because they're backup sights and the RMR's are easily tuned to hit exactly where I want them to, but the P226 is another story.
Even more aggrevating is that not only are the Heinies not POA = POI, they're not even 6:00. They're freaking worse than that! 6:00 hold still yields high hits. I emailed Heinie about the MOS sights when I got them and their response was nothing helpful. Makes me want to just go Dawson with their Perfect Impact Guarantee for everything!
