I have a S&W M69 .44 (4.2" barrel) and Ruger Redhawk 45 Colt (4" barrel).
Both have nearly the same foot print (although the Ruger is thicker ie 6 rnds vs 5) and as to wt. the Smith is 38 oz. and the Ruger 45 oz. I don't have an M29 but Smith claims a wt. of 44 oz. I'd also add, the Smith has a much better trigger without mods.
