I ordered 5 Promag 32's from Tactical Vantage on 3/19, and they shipped on 3/22. Should have them this Tuesday. I have the same mags on backorder since early Feb from Promag, and still no word.
If I could have ordered a dozen S&W mags, I would have done so directly from S&W. A bunch of S&W mags I have on backorder with various vendors are due in who-knows-when. Cabelas has pushed back my BO from Feb to Dec 2013. Since a ban will be in effect here in Colorado, or should I say the new Cali-rado, I don't expect to ever see my Cabelas order.
So unfortunately, I have to settle for the Promags, as I only have 1 S&W mag right now. Also have the Black Dog Machine 50 rounder, but the ammo with the wax coating tends to bind in the neck by the 4th or 5th load, and then needs to be cleaned.
