MecGar or Checkmate Mags? SIG ANSWERS THE QUESTION Just got off the phone with Andy at Sig Sauer in NH. Very friendly and helpful. I asked him whether or not Sig now supplies their pistols with Mec Gars or are they still supplying them with Checkmate? The answer: Totally hit/miss and luck of the draw. They have two sources for mags: Checkmate and MecGar and it all comes down to whatever they happen to have on hand "to meet the high demand for pistols and magazines" ... so, if they happen to have Checkmates in stock, those get shipped out with all their pistols, if they happen to have MecGars...yup, you get MecGars. So, there is NO rhyme or reason to which magazines your Sig Sauer pistol comes with. Hope that helps settle the "why Checkmate or MecGar" when it comes to what is supplied with your Sig Sauer handgun. I also politely told him that I and many other SIG owners I'm talking to on various gun forums have had no end of problems with the Checkmate magazines, but that the MecGars work perfectly. He did not really respond, but just said, "We have to use two suppliers to meet demand." But, at least I told him. Great conversation. Kudos to Andy at SIG for his professionalism and friendly style and manner. Good customer service goes a long, long way toward building customer loyalty.
