The Walker Colts were originaly "packed" by horses in saddle mounted holsters according to accounts during the US-Mexican War (1846-1848)(yes they were indeed horse pistols). Each Walker Colt weighs around 64 oz. (4 Lbs), not exactly a pocket pistol. So Col. Colt paired down and modified the Walker and came up with the Dragoon Series of revolvers, smaller but still hardly man packable. It was until Colt came out with the 1860 Army Model that he struck a balance between power and weight. You can find holsters for the Walker but you may need suspenders to distribute the weight.
