I've got 4 different Rugers with fixed sights - a Vaquero .45 45/8 bbl, Single Six .32 H&R, Single Six 50th Anniversary, and a Bearcat. All of them out of the box shot low for me anywhere from 2 to 4 inches at 25 yds depending on the loads. Is this by design? Or is it me? Since they're shooting low it's fairly easy to correct, but it's still a little disconcerting to go filing on a fixed sight (although I don't plan to touch the Single Six 50th).
