GLOCK 21 GEN 3 SF

Overview

The GLOCK 21 Gen 3 SF (Short Frame) was introduced by Glock in 2007 as a specialized variant of the standard 3rd Generation GLOCK 21, designed to bridge the gap between high-capacity .45 ACP firepower and ergonomic comfort. While based on the popular Generation 3 platform, the SF model was developed specifically to address complaints that the standard G21 grip was too large for many shooters, particularly for potential military and law enforcement contracts.
