So I'm moving my targets out a bit on my G23 and I find that I'm just not as accurate as I could be. My front sight is just so much larger than the target that it looks like I could move it left or right a bit and still be "on". Since I know this is not the case (the results proved it!) I wonder if it is time for better sights. Has anyone else had similar results with their stock sights? Anyone find improvements from an upgrade?
