I was asking about a holster at a local gun shop this weekend and the salesperson suggested to always bring the gun to the store. You might find something that will fit even if it isn't designed to. I carry my Kahr PM9 in a holster made for the PM40 for instance. While your case will be more extreme it is possible something will work.
Sourdough44, You have a RAGING Judge? I sent them a query for a holster for my Raging Judge Magnum and they responded with "sorry, we do not currently make a holster for that weapon as we do not have a sample gun for the template."
No I do not have a 'Judge' in any flavor. My brother has one though & I bought him a Simply Rugged holster. He possibly has a more common, smaller judge. I thought they could custom make about any size.
I did notice there are a ton of holsters listed on ebay, various quality of course. I did see a lot of nylon options listed, may be worth a look.
