I have been trying to locate a colt saa 44-40. I am looking to shoot it so thinking I need to stay with 3rd gen but interested in folks thoughts. While an older 1st gen would be extremely cool, not sure I want to incur that level expense for as much as I hope to use it. Also was thinking a 5 1/2 in barrel but they seem hard to fine so if anyone knows of any good places to search. I've been checking gun broker and guns international quite regularly.
