Picked up a 3913 the other day, unfortunately only with two factory mags, so the search for extras is on.

Now, factory mags range anywhere from $34 to $45 depending on what website you check, but I noticed that ProMag makes one priced at roughly half that. ($19-$22) They would make good range mags and save me close to a 50 bucks. I'm not intending these to be carry mags.

Anyone have experience with these things? I do have Some Beretta 92 Promags, and they have worked fine over the years, but I bought those a long time ago.
