I was 16 when I got my first handgun, a Colt single action .22. I loved that gun, but it shot way left. My dad simply bent the front sight, and I was on target. I didn't like that bent sight, but I learned a lot about revolver accuracy with that Colt.
Now, at 63, much older than my dad when he bent that front sight, if I buy a fixed sight gun that shoots that far off center, I get rid of it. If you are shooting 3" left at 10 yards, you are way the heck off at 25 yards. You will never be able to compensate for that much deviation from center.
Regarding Colt single action revolvers, they are super expensive because of the name and the beautiful finish and the classic lines. I'd love to have one. But buying a Colt revolver is luck of the draw. Sometimes you get one that shoots tight groups at the point of aim, and sometimes you get one that won't group at all. Another drawback with a Colt, is the inherent weakness. We can shoot cowboy loads forevermore thru a Colt, but we can't load it hot. With all that in mind, I'll stick with Rugers.
