Very nice! I love the gunbelt! UHC does make a black on black version of that revolver for around $35.
I grabbed an airsoft version of the Colt Python that has very similar characteristics to the Taurus 66, especially with the grip. It was $60 and it's all metal. Holster was about $30. I did decide to modify it slightly as the original piece covered the trigger and Joel's holster does now. I just dyed and weathered it this weekend to look more beaten up like Joel's in the show and I'm pleased with how it turned out!
