My favorite, a pristine 15-3 I bought unfired from an estate, no longer lives here. I couldn't see making my son and his three boys wait till I croak, and gave it to them. They shoot it often with great pleasure. A master smith gave it the most wonderful trigger I've ever encountered on any firearm, ever.
My present favorite is the 4" standard-barrel 10-5 that stays in the head of my bed in case of goblins and miscreants. Not pretty--the previous owner coated it with something like Duracoat, and I bought it for knocking around the woods in bad weather. Now I can't do that anymore, but it's very serviceable. And hey, it's a Model 10, something everyone needs to own.
