Need barrel for American Arms Revolver

[4 eyed six shooter]

I'm looking for a parts source that would have a barrel for an American Arms S/A revolver. It is a 45 LC, 3.5" and is marked
"Regulator", it is for their ejectorless model. I know I can use another make barrel, but my customer wants to keep it original if possible.
I've tried Jack First and GPC with no luck. Anybody know of another source?
Thank you, John K

Thank you JM. I looked in the catalog but didn't think of the web site for whatever reason. All they had was the 7.5" barrel so I ordered it and will cut it down to 3" and mill a slot for the new sight. The guy I got it from fired a squib load and then shot a good one behind it. Split the barrel like a banana all the way to the front of the frame. I'm going to have to talk with him about his handloads as he also brought in a Ruger 44 mag 6 months ago with the same problem.
Best wishes and good shooting, John K
