If the OP is at all like you're truly, you've got to feel good about both the gun and the deal. Depending on the condition of that 4566, $400 could have been a great deal, a good deal, or possibly just fair. Last non-TSW 4566 I came across was tagged at $549... probably out the door for $500 knowing that dealer. It was in fantastic shape (not an ex-cop gun) and if I didn't already own two TSW's, I'd have gone for it. It had sold by the next time I stopped at that shop.
