So, I'll not get into issues of age and ineptitude to describe my shooting abilities. I have a Sig 226 that I LOVE to shoot, but just couldn't do anything with the iron sights. I bought a Holosun red dot, and a dovetail mount from EGW. Maybe I should have had the slide machined, but I'm so happy with the current setup, I couldn't imagine changing it. Low cost, great results, go figure
