Your 1911 is only as reliable as its magazine. You can have a top tier 1911, but if it's fed from a sub-par magazine you'll only run into trouble. Weather you have a Colt Gold Cup, a Kimber Custom II, a Rock Island 1911, or anything in between - make sure you have quality 1911 magazines for it. We carry top tier 1911 mags from Chip McCormick and Kimber.
