After going to the range a few times with my Glock to see if it actually shoots very low or if it is my fault. After today I am sure it is the gun as every other pistol i shot with today (2 others including a 1911 and a g26) I shot very well with. I pretty much have to "snowman" the sights and still cover the target with the front sight to hit well with it at any distance. What are my options? I would rather not buy new sights if possible, it has night sights. Would my best option be filing down the front sight slighly and using some touchup paint?
