    • Glock 20, 21, 20SF and 21SF (Glock Rail only)

    Glock 20 - Introduced by Glock in 1990, the Glock 20 was designed for American law enforcement who were adopting the powerful 10mm caliber. Although classified as a “full size” Glock model, the G-20 frame is larger and wider than the “full size” Glock 17 series. This was necessary in order to accommodate the higher pressure of a 10mm cartridge. Although the 10mm is not as popular with law enforcement today, the G-20 is still popular for both self defense and hunting.

    Glock 21 – Introduced by Glock in 1990, the Glock 21 is a 45 ACP caliber pistol was designed to target the American law enforcement market. The resurgence of the .45 ACP caliber in law enforcement played part in the development of the G-21. Built on a similar frame as the related Glock 20, the G-21 is larger than the ever popular Glock 17. Carrying 13 rounds of .45 ACP ammunition, the Glock 21 became popular with law enforcement agencies that were transitioning to the more potent .45 round.

    Glock 20SF – Released to the market in 2007, the G20SF featured a slightly shortened frame (with SF standing for “Short Frame”). The concept behind the SF series centered on the idea that the smaller frame would be more comfortable and manageable for shooters with smaller hands.

    Glock 21SF – Introduced by Glock in 2007, the SF designation stands for “Short Frame”. Chambered in 45 ACP, the G-21SF features a shorter and narrower grip frame was built on 2 premises:

    (1)    Hopes that the US military would offer another pistol trial to potentially replace the Beretta 92 and the shortened grip was a closer match to the grip size on the current Beretta 92 (which didn’t occur)

    (2)    The shorter grip would work for law enforcement use for officers with smaller hands.

    In anticipation of a potential military evaluation, some of the early SF models featured a 1913 style picatinny rail while others featured the standard Glock rail. Today, the G-21SF models feature a standard Glock rail.

    Although slides and frames for Glock 20, Glock 21, Glock 20SF, and Glock 21SF are not interchangeable, all 4 pistols feature dimensions that are close enough to fit in a holster built on the G-20/G-21 frame.

    Holsters listed on the page will fit the Glock 20, Glock 21, Glock 20SF, and Glock 21SF with a Glock rail.
