I've seen a lot of questions on "how do I get my revolver to shoot where it's aimed". Here are some photos of my solutions. This concentrates on the front sight but rear sights need some work as well. Whether hammer notch or frame notch It will most likely need to be filed deeper and wider to provide a decent sight picture that is consistently repeatable. But it is the front that seems to give folks the most trouble.
Here are some front sights I have installed on revolvers. The 1851 Navy was the simplest, just a taller pin. It may look like it would gouge a holster but it is nicely tapered and smoothly rounded and causes no problems in a Slim Jim holster. I dovetailed the 1860 Army to take an old sight I had in my "miscellaneous parts box". I got along with just lifting the factory sight a bit out of it's slot until I added a .45 Colt conversion cylinder, then it needed to be much taller. The last is on an 1862 Police I did for a buddy. He will have to cut it down to proper elevation and probably round off the sharp corners but at least he now has something to work with. A dovetailed front provides windage adjustment as well as correcting height.
