Hi All, Just snagged a Glock 21 that I plan on using for carry and paper punching. After doing alot of reading, I have decided on the plain Warren Tactical rear sight, but have questions on the front sight. I plan on going with the narrower fiber optic front blade at .115 wide (versus .125) but I'm not sure about the height. I plan on having Chris over at www.cpwsa.com put them on for me and on his site it says: "All Warren Tactical and Sevigny sights are designed for a six o'clock hold with the .215 tall front, or to shoot point of aim/point of impact with the .245 tall front sight." I want the point of impact to = the point of aim. In other words, I want the bullet to impact right at the point of the front site blade. Knowing that, I would (based on the statement from his site) choose the .245 height. Yet when I read posts on this forum, I think most of the guys that run these sights say they have the .215 setup with my desired results. Can anyone comment . . . I hate to get the wrong thing.
