By the way, if you need any help with it, I could call Cimarron and see what they have. Basically your gun dealer needs to be on file, if not, the first time the dealer must call them and give them all the info they want. This took several back and forth phone calls to get it right.
TIP: Make sure you get the name of the person you are dealing with at Cimarron from the get go, and if you need to make follow up calls insist on talking to that person even if you need to hold for a little while. It worked like a charm.
UPDATE:
Just got off the phone with Cimarron. They have an Uberti .45 Model P old style, but it is in 4 3/4
Also, they do have an original style SAA from Pietta that is .45 and 5 1/2 - nothing wrong with Pietta.
General. I will email you the name of the person that WILL help you right away. Sent the email to the one you have posted here. Let me know if I can help in any other way.
