About Glock 21

The Glock 21 is a high-capacity, .45 ACP pistol renowned for combining substantial stopping power with the reliability and durability characteristic of Glock firearms. This model is particularly noted for its large magazine capacity, holding more rounds than typical .45 ACP pistols, which makes it a popular choice among law enforcement agencies and civilian shooters who prefer the powerful .45 ACP caliber. Despite its larger size to accommodate the bigger caliber, the Glock 21 is designed with ergonomics in mind, ensuring comfortable handling and operability. It's a solid choice for those seeking a reliable, high-capacity firearm for self-defense, duty use, or target shooting.
