There's a used, stainless S&W Model 19
I didn't comment on that because others had covered the fact that the M19 is usually blued carbon steel, the equivelent in stainless is the M66. However, it just occured to me that if the dealer had it labeled as a M19 and it looked stainless it still may be a 19. It could have the nickel finish.If it's stainless steel, it's not a Model 19
I also covered the nickle-plated option in the second paragraph of my post, Chaim
BTW, the worst, most worn-out Python on earth still has a smoother action, better trigger, and better accuracy than the newest, best thing S&W makes.
