DeerSlug,

I have an 8 3/8 inch barrel M586 on hold at my LGS. Price is $595.00+ tax. This is in my area and he is a bit high on most things. The only holsters I have carreid 8 3/8 inch guns in is the Bianchi X15. I think it's the extra large version. The large version will carry the six inch barrel. Bianchi has a website with a sizing chart that lists part numbers. Take a look. I'm sure there are a lot of other holster out there but I prefer a shoulder holster for the long barrel guns. Hope this helps and good luck.
