The Military Armament Corporation Model 11, often referred to as the MAC-11, is a compact submachine gun chambered in 9mm. Aftermarket accessories, such as 50-round magazines and drums holding up to 100 rounds, manufactured by companies like MasterPiece Arms, are sometimes available for this firearm. These high-capacity magazines significantly increase the amount of ammunition available before reloading.
High-capacity magazines for firearms like the MAC-11 offer advantages in sustained automatic fire scenarios. However, they also raise significant debate regarding firearm regulation and responsible use due to their potential for increased casualties in the wrong hands. The development and availability of such accessories play a role in the ongoing discussions surrounding firearm ownership and public safety.
