The Glock 37, chambered in .45 GAP (Glock Automatic Pistol), is compatible with high-capacity magazines that extend beyond the standard round count. These accessories provide increased firepower before requiring a reload, a feature often desirable for competitive shooting or self-defense.
Higher capacity magazines offer a tactical advantage in situations where reloading quickly might be difficult or dangerous. This increased capacity is balanced by factors such as weight and potential printing (magazine visibility through clothing). The .45 GAP cartridge itself was developed as a more compact alternative to the .45 ACP, allowing for a smaller frame size while retaining similar ballistic performance. This makes the Glock 37, especially when coupled with an extended magazine, a compelling option for those seeking a balance between firepower and concealability.
