I picked up a 3913 (SN: VDF7121) this weekend with a 4 mags and a Bianchi 717 holster. All show honest wear, but not abused. I have never owned one and I'm wondering what people think of this piece. The only issue it seems to have is the left grip panel has a little play at the top, where the slide hold open detent goes against the metal part under the grip panel. Is this a serious issue, or should I not worry about it? I have not fired it yet, but It is going to the range soon. I thought $300 was a decent price to pay, but a little range time is neede to prove that.
