I have owned several replica Colt cap and ball revolvers over the years, had an 1847 Walker, two 1851 Navy's, and a Pietta 1860 Army. Thinking of getting the Uberti 1860 Army later this year as the grip fits my hand, it is streamlined, with a better loading lever setup, etc. The Walker was too big and heavy, the 1851's grips are too small.
I also might look at other types too, but again the grips are small on the 1861, the 1862 Police, and the baby dragoon. I chose not to include other revolvers like the Remington, I have one of those and it is a different animal than what ol' Sam Colt designed.
Overall, what has been your personal favorite of the replica cap and ball Colts.
