SPD Mag’s goal was to create a firearms magazine that is effortless and extremely fast, taking mere seconds to load without help from a magazine loader or speed-loading mechanism.
SPD Mag’s products (patented, made and assembled in the USA) are a magazine accessory which we coupled to an OEM (original equipment manufacturer) magazine tube and spring. The country of origin depends on the brand of firearms; i.e., Glock: Austria or USA. This converts an ordinary magazine into an SPD Mag, except for our AR-15 magazine, which is made by us from 30% carbon fiber reinforced polymer in the USA. The decision to use OEM magazine tubes is because they meet our standards of quality and reliability.
SPD Mag’s products are made of only the highest quality materials. The polymer parts, including the follower, are made from 30% carbon fiber reinforced polymer, not glass-filled as found in other firearms products. Also, the metal parts are 6061 anodized swiss machine aluminum, 302 stainless steel, and 17-7 stainless steel.
