Glock 21

History

The Glock 21 (Glock GmbH in Austria) is essentially a modified Glock 20 model for the US market, including the . 45 ACP. That . The 45 ACP (or ".45 Auto") cartridge is a rimless cartridge developed in 1904 by American gunsmith John Browning. This . The 45 ACP is featured in the legendary Colt M1911 semi-automatic pistol, which became the primary weapon of the U.S. Army in 1911.

Large cartridges proved effective enough, albeit at the cost of low energy output. Nonetheless, the Glock 21 exists to meet market demand for police sidearms and general self-defense weapons.

The frame of the Glock 21 was larger than previous Glock iterations and came into production form in 1990. The Glock 20 frame was used as the starting point for the Glock 21 to make way for new magazines to accommodate larger bullets and new slides. The barrel has an octagonal hole compared to the hex type on other Glocks.

The grip has been enlarged to accommodate the new magazine, making the new Glock 21 suitable for those with "big hands". The standard magazine holds 13 rounds, again due to the larger cartridges, which must be staggered in the magazine. As with other semi-automatic pistols, the magazine is inserted into the bottom of the grip.

Curb weight is 26.28 ounces. The length is 7.59 inches and the barrel length is 4.61 inches.

Externally, the Glock 21 looks very similar to the Glock 20, with the most notable exception being the enlarged grip.
