I was just about to say that! I use Fobus mag carriers at the range all the time! For the price, can't be beat!Fobus 9/40 double stack paddle carrier. Their holsters might not be the best (although my USPc rides perfectly in one), their mag carriers are way cool for the price. But get the paddle!
BIG +1! Comp-Tac makes the BEST kydex holsters and accessories on the market and their customer serive is second to none.Comp-Tac! If they make it for your gun, it's the best you can get. Slightly better than Bladetech (I've had a lot of both) AND they tell you it might take 1.5 weeks, but you usually get it the same week. With cheerful Texan service and very reasonable pricing. Bladetech products are very good, and the service is good, but the lead-time and pricing are ... painful! Comp-Tac mag carriers are easy on/off, stable, secure, and perfect workmanship.
I love the Kytac and Ready Tactical stuff.Two singles are generally better than one double mag carrier. Most double mag carriers do not provide individual retention for each mag. Some double mag carriers make a a good grip and smooth draw on the rearmost mag very difficult. If I was stuck on getting a double mag carrier, I would probably go with Hoffners. For single mag carriers, I would recommend iShot, Ready Tactical, or Kytac.
