What 1st, 2nd or 3rd Gen S&W auto would you buy if you could only have one? I would like to fulfill this genre of pistol for my collection and find something around $300-500 on the used market. When I think of the old Smith autos I think betamax, delorians and the 80s. I also think of sw40 being introduced and gaining popularity. Just curious what one pistol sums up the pinnacle or icon of this model of pistol.
