Metalform, along with Mecgar and Checkmate, are the major manufacturers of OEM magazines for many firearms makers. This includes Colt, S&W, Beretta, Kimber, and others. I would not hesitate to purchase any of these if they list a magazine for the gun you are interested in. There is a possibility the Sig OEM magazines are made by one of these manufacturers. Contact Sig USA, they may tell you.
