Here's my 2 cents. Find somebody who has a collimater they know is correct. Use it to see if indeed the sights are off. If they are, tighten the barrel a tad. If not, learn to grip it with the bore lined up with the bones in your forearm and not push it left when firing. I see this so often it's not funny, and it almost always comes from the way folks want to hold onto single action grips. But sometimes they do need to be regulated, and most of the time just a tiny bit of tightening will solve the problem. Whatever you do, don't try to bend the front sight! It will break off and then you will really have a mess.
