El Paso Saddlery. They can accommodate the odd barrel length and do excellent work. I think I'd get their Model 2, about like Safariland's old Model 29. El Paso Saddlery – Custom Leather Holsters & More
I think Safariland made them for five-inch barrels, but probably only if they got an order for one, so few, if any, on the used market.
I presume you want something nicer than a webbing British military holster. Those only fit their web belts, anyway.
EPS's Model 1920 Threepersons is also a good choice. They have pancake styles for concealed use, too. But a five-inch barrel may be stretching things for that use.
Pay for a lined holster. Your gun's finish will thank you. I also like their basketweave stamping and they do exquisite floral work, if that appeals to you.
