I picked up a leather Hunter holster from wal mart in 1972. I use it for all of my Long barrelled pistols. After 40 years of exposure to conditions ranging from Lousiana Swamps to Minnesota blizards and marshes, it has retained its form and the strap retains the pistol.
It has carried replica cap and ball remingtons and colts. A couple of Peace makers, a Ruger Blackhawk and now my DW when I mount the 8 inch barrell.
For the price the leather was excellent and it never gave me a problem. I doubt that you can find that quality today at a reasonable price.
