question for you pistola guru's. My colt commander 45acp is shooting 6-8 inches low and left. I can fix the left but the vertical is a whole nuther ball game. My good buddies JDS and Pullit have me going in the right direction but I need a little more help. I am going to buy a new front and rear sight, I like night sights so that is what I want. The fronsight I have now is .185 tall, how low do I go with the new front sight. I can get .170 to .160 which one should I go with?
