I don't think the accuracy is a gun issue, I think it is more an issue of can you hold and squeeze the lightweight J-frame as well as the heavier and larger K-frame revolver? I think the accuracy is built in there like any S&W revolver. But I know I cannot shoot my M63 as well as my M18 4" K-frame at longer ranges. And not even in the same ball park as my M17 6" gun. The little lightweight is harder to hold steady IMHO than the heavier and larger guns. At closer ranges the difference isn't much. But the farther the target, the more you can feel and tell the difference as you shoot.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
