FWIW I have used a pair of Uberti Second Model Dragoons at Cowboy shoots. Of course that's only about 7-8 hours of walking around and I normally use other guns, but it didn't seem too bad. The Dragoons were very pleasant to shoot. I just finished up a pair of Uberti Walkers and will have to wait until next season to see how that goes.
Did you use suspenders for them dragoon’s?
