Pro Mag Industries 1911 Blue Magazine Features The ProMag Magazine for 1911 is built from heat treated steel for long-term durability under the repeated stress of loading unloading and magazine changes at the range. Its black oxide finish resists corrosion and wear helping the magazine hold up to regular carry and training use over years of service. A 13-round capacity gives 1911 shooters in 9mm Luger a useful boost over standard-capacity factory magazines extending time on target between reloads. The magazine spring is formed from heat treated chrome silicone wire a material chosen specifically for its ability to retain tension over thousands of loading cycles without weakening. An injection molded follower rides smoothly inside the magazine body helping ensure reliable feeding of each round all the way to slide lock. Because it is a direct fit for 1911 pattern 9mm pistols this magazine is a straightforward way to add a reliable spare to a range bag or duty belt without hunting for a factory-only part. Made entirely in the USA the ProMag Magazine for 1911 reflects the company s long-standing reputation for producing affordable functional magazines across a wide range of pistol platforms. For 1911 shooters looking for a dependable extra magazine at a reasonable price this one is available for sale at GrabAGun.
