Sounds like the GLOCK grip angle points well and quickly for you. Try closing your eyes and pushing the G23 out to the target, then open your eyes and see how the sights are lined up; I bet they will be dead on. Are you running the stock sights on your G23? I switched out the plastic sights for 10-8 Performance U notch rear and bead front. They are outstanding, plenty of light around the front sight and the U vs. squared off rear lines up the front naturally for me.
