I have a G23 that has a set of AmeriGlo night sights on it, which are crap. The front sight is barley visible in pitch black and one rear dot is visibly darker than the other. So, I have a G20 that has a year old set of Meprolight 10222s on it. I was thinking of putting the 10222s on my G23, but Im wonding what adverse effects this might have. From what I was able to find out from the web is that most likely if I did swap the point of impact would be higher than point of aim. Any thoughts would be appreciated, thanks. Happy Shootin.
