I figured I would bounce this off of everyone here and get your thoughts. I have a Canik TP-9 pistol. (Walther P99 Clone). I love it. The only issue I am finding is that at 10 yards, I hit about 3 inches below my sights. The front is fixed and the rear are only adjustable for windage. Any thoughts on how to fix this? Other than just aiming high?? The gun did come with 3 sizes of front post and I currently have the lowest/smallest one in there. Any suggestions would be greatly appreciated.
