Ruger SBH Bisley Hunter is best option you can find. Just 3 oz less than FA M83 is more than enough weight to have pleasant shooting with .44 Mag. Very easy to install optics or red dot and to replace front sight if you prefer other than red ramp. If you are considering DA, pls mind Ruger Redhawk instead of SW; waaay stronger construction and significantly smaller grips which you might find interesting. I personally have RH 7 1/2" but as my eyes are getting older, I became fun of a red dot. With that in mind, sight radius have less importance and I would swop 7 1/2" with 5 1/2" TODAY.
