About Glock 21SF

The Glock 21 SF (Short Frame) is a variant of the Glock 21, designed to offer the same high capacity and powerful .45 ACP performance in a frame that is more comfortable for shooters with smaller hands. The "SF" designation stands for "Short Frame," which refers to the reduced circumference of the grip, improving ergonomics and control for a wider range of users. This model maintains the standard Glock 21's 13-round magazine capacity and its reputation for reliability and durability. The Glock 21 SF is particularly popular among law enforcement, military, and civilian shooters who appreciate the potent .45 ACP caliber but prefer a more manageable grip size for better handling and comfort.
