I am looking into getting a set of Heinie QWIK SlantPro Night Sights for my Gen 4 G22 and in the future G23. I wanted to know what experience people had with the different front sight heights for their G22. What height do you have and does it shoot POA/POI or other? I would also like to know the same for the G23. Additionally, I know there are many other factors, hold, ammo etc. I will be using 180 grain ammo (AE/HST/AA) and ranges for either 15 or 25 yards. Thanks!
