Mal, I`m sure they are off on windage. I tested them off a bench, (sitting, with my wrists supported, and very carefully aligning the sights.) I used a couple different loads of mine, and both guns are shooting to the left, one 3", the other about 4" from center, at 25 yds. My latest Vaquero is a stainless, 4 5/8", 45 LC/45 ACP convertable, and I can actually see the front blade listing to the right (while aiming). Can I tighten the barrel, like a Colt SAA, to bring my poi to the right? In the Smithy section I got a yes, do you agree? Thanx-
