Good luck with that gun. You will probably have to get a Uncle Mikes, Galco, etc for another gun and just fit it right. I checked into a Model 10 at a good price but after checking with multiple quality holster makers and finding nothing for them I decided against the gun. Sorry!
Don't Tread On Me is what it says and I'll take that to my grave.
Try looking into Cross Breed Supertuck holsters and K Holsters. They are both good rigs and they can do custom stuff. The Supertuck is higher quality but is twice the cost of the $40 K Holster. They both fit similarly. You never know. They might have what you're looking for.
Try El Paso Saddlery's website. They're out of El Paso TX. I think it's epsaddlery.com Order only by phone or net. Not Cheap. Maybe an 8 week wait. Well worth it! Quality throughout and you'll be well pleased.
By the way, that 2" S&W Model 10 is a heck of a fine revolver. I sold mine...wish I had it back.
