STI 2011 Magazine
The STI Generation 2 double stack magazine is a redesign of the magazine STI has been manufacturing for its line of 2011 double-stack/wide body pistols. The magazine body has been set to precise and consistent measurements at the lips and throughout the length of the tube both front-to-back and side-to-side. This translates into more consistent reliability and performance. In addition, features such as witness holes and polished interior/exterior of the mag body further enhance the quality of these magazines. In the 2017 platform, the “ribs” of the 9/.38 magazine run all the way down both sides of the mag body and, thus, make the spacer unnecessary for 9mm. Consequently the 9mm and 38 Super mags are identical. You might find that the mags are stamped “9MM” but, rest assured, they are also used for 38 Super.
