Well I purchased a 5.5 inch barreled Uberti 1858 .44, and I am now looking for a decent holster for it that won't break the bank. Main uses for the gun are largely recreational of course, but I wouldn't mind taking it along as a backup during muzzleloader season either.
My own searching has found a couple of options on Ebay and Etsy, of which I'm not sure, and I have no experience with most if the styles of holster that are generally offered for this type of gun.
