Many of the guns I've seen listed in this thread, especially the Rugers, I have seen, have seen offered for sale, or I own. Some are not exactly common to see though such as a Redhawk in .357mag.
I have a BLUED 5 1/2" .41mag Redhawk. At the gunshow I saw the Daisy VL ammo for sale this weekend and I also saw the single shot .22lr Daisy for sale at $50. I have a S&W 25-2 mod of 1955 in .45acp. They are out there but I don't see them everyday.
