I recently picked up a pair for my G23 (TG131G1) with hopes that the FO attributes would allow me to pick up the front sight faster. Well, I can tell you that they definitely make that possible as they're bright as hell when it's sunny outside. Low light, I would say they're about equal as any other non-night sight setup. The green (rear), and red (front) really allow you to pick up the front post.
Anyway, I've made a few trips to the range and shot a couple of matches both indoor and outdoor, and when it came down to sighting in so that point of impact equaled point of aim, I had to drift the rear sight quite a bit to the right (almost to the max adjustment point).
I have had some other competent shooters, as well as a bench verify my adjustments, so I am confident that it's not a shooter issue. The interesting thing is the my Meprolight night sights that these replaced, we're pretty much centered on the slide for point if impact to equal point of aim, which make sme think that maybe the sights I have are a little bit out of spec.
Has anyone experienced anything like this before or have any input? I guess, I'm just kind of anal and want everything to be symmetrical so this drives me nuts everything I look down the sights.
