I've got a Smith & Wesson model 3913. It's stainless steel, 9mm parabellum, Novak night sites, factory black grips, and two 8 round mags. The serial number is vam33**. It's in great shape and shoots perfect with cheap russian ammo or the really expensive personal defense ammo. Any info on when it was built and what it's value is would be nice. Thanks.
