The Glock 21 is a pistol manufactured by Glock. It is a large frame Glock based on the Glock 20 and fires the .45 ACP ammunition. It uses a modified Glock 20 frame, .45 ACP barrel, modified slide and magazine but these differences are quite minor and it does look identical to a Glock 20. It is a very popular sports and law enforcement pistol in the United States, because of its reputation for rugged dependability, 13-round magazine capacity, and it being chambered in the popular and effective .45 ACP cartridge.
Like most .45 autos its large frame size makes it uncomfortable for many people but is well suited for those with larger hands.
The Glock 21 has undergone 3 major revisions since its introduction and current models are called 3rd generation Glock 21s.
The difference between the Glock 21 and the Glock 21C is that the barrel and slide are compensated on the C model to reduce muzzle climb while shooting the pistol.
Additionally, there are Glock 21 "Mariner" (underwater firing capability) / "Tactical" (Extended/Threaded Barrel) Models available in the Philippines.

[edit] Glock 21SF (Short Frame)
Another revision hit the market in Spring 2007, in an attempt to make fullsize .45 Glock more appealing to shooters with smaller hands. Glock has releasd the model 21SF, which stands for "Short Frame". The pistol was originally designed to compete in the now cancelled US Military Trials that were searching for a .45 acp pistol to replace the Beretta M9. The first 21SF's designed for the military included revisions such as ambidextrous magazine release and picatinny rail system (which replaces the standard 1913 rail system on other Glock pistols), along with the frame reduction designed to make the grip more universal. The grip reduction removed material mainly from the backstrap of the grip, and is where the moniker "Short Frame" is derived. Initial information is that only a limited number of 21SF's in full military spec will enter the public market, and that the company is going to mass produce a grip reduced model with the 1913 style frame rails. It is not clear if the ambidextrous magazine releases will remain, but it is unlikely considering they require a modified magazine and will not secure current Model 21 magazines.
