The G21 SF (Short Frame) configuration shortens the front-to-back grip dimension and trigger reach, offering a more manageable hold while maintaining the full-size .45 ACP frame and 13+1 capacity. This is a Gen 3 pistol with the familiar finger grooves and a standard left-side magazine release.
Its 4.6 in barrel is cold-hammer-forged with polygonal rifling, designed to provide durability and consistent performance. Both the barrel and slide receive a Tenifer-type nitrided treatment, presenting a matte black finish.
The polymer frame is finished in black and includes integrated Glock safeties: trigger safety, firing pin safety, and drop safety. The pistol uses a striker-fired action and a single-sided, left-side magazine release.
Sighting is straightforward with fixed polymer sights: a white-dot front and a white-outline rear. A three-slot MIL-STD-1913 Picatinny accessory rail on the dust cover allows mounting compatible lights or other rail-mounted accessories.
Markings include MADE IN AUSTRIA and GLOCK, INC., SMYRNA, GA, reflecting Austrian manufacture with U.S. import designation. The package includes four Glock factory magazines: two 13-round and two 10-round options.
