I picked up a Sig 1911 45 ACP Nightmare fastback recently. I am looking to get a few more magazines for it. It came with 2 factory 8 round magazines. I was wondering if anyone has a favorite other then factory magazines? I have heard good things about Chip McCormick and Wilson Combat or is it better to stick with factory magazines? Let me know what you are running in your 1911s and how they function. Thanks.
