LGS has a decent condition used S&W 4006 with one magazine (10 round) for asking price of $319. I know these are older and not particularly favored, plus being a .40 rather than a 9mm, but that seemed very cheap to me. The bore was good, the single action trigger decent and the only marks on the gun were a couple of small rubs on the top of the slide.

Did I screw up by not buying it on the spot? I have a 39-2 and a 5906 so I don't really need another S&W double action semi, but the price really shocked me.
