I just picked up a S&W 4506, NIB, with night sights, for $200 under list, and now I'm wondering if it was a brilliant example of opportunistic value creation, or just another impulse buy. I've always been a single action buyer, favoring 1911's. A couple of Glocks, since they're the only 10mm game in town. As a matter of fact, I have no .45 acp's that are not 1911 format. But the salesguy had all the right arguments: not being made any more, best .45 S&W makes, sturdy as a tank, he bought the next to last one, the S&W reps all bought them, etc. So, any one with a 4506 out there that can ease my conscience? Did I do ok?
