Hellcat 9mm magazine by the Springfield Armory with 15 round capacity is a marvel of innovation. The Springfield Hellcat was born out of its magazine. The designers at Springfield designed and crafted the worlds most high capacity micro compact magazine to fit in their highly successful Hellcat series of pistols. The 15 round mag features a finger rest to allow the user to acquire a full proper grip on the pistol for stability and control. The stainless steel construction of the Hellcat magazine allows for slick and easy magazine insertion into the pistol while the stainless steel construction allows for a thinner profile which accommodates 15 rounds of 9mm to fit in a small package.
