Chip McCormick Match Grade Magazine for 1911 Full Size Features The Chip McCormick Match Grade Magazine for 1911 Full Size is held to die-controlled tolerances of plus or minus .001 inch a standard more than 75 percent tighter than typical military specification magazines. That precision comes from improvements to follower design and feed lip geometry both engineered to feed reliably even in dirty environments. A high tensile Rocket Wire spring made from aerospace-grade material provides long-lasting tension so function does not fade as the magazine ages. Large numbered witness holes let shooters check round count at a glance without pulling the magazine to look. Built from improved tolerance stainless steel the magazine resists corrosion while its smooth finish allows easy insertion and removal under stress. The stainless steel follower pairs with the heavy-duty spring for durability that holds up to repeated reloads on the range or in competition. It sits flush for minimal bulk and easy concealment and it is drilled for a base pad though the pad and screws are sold separately for shooters who want to add one. Built for the full size 1911 platform in 9mm this Match Grade Magazine gives serious 1911 shooters a tighter more dependable alternative to a factory magazine.
