If you don't want to spend big $$, Cabelas has your holster for under $25.
I bought all my leather from
https://westernandwildlifewonders.com and could not be more pleased with the service, price and quality.
A complete two gun rig is under $175 including shipping.
I have a set of Ruger New Model Vaqueros and a set of 1858 Remingtons. Both with 5.5" barrels and they both fit nicely into the "Bounty Hunter" holsters from WWW...........
The above rig was $168..........
