About Glock 21 MOS

The Glock 21 MOS (Modular Optic System) brings the advanced features of optic adaptability to the high-capacity, .45 ACP platform. This model allows shooters to easily mount a wide range of reflex sights directly onto the slide, enhancing accuracy and speed in target acquisition. The 21 MOS maintains the robust construction and reliability characteristic of Glock, while its chambering in .45 ACP offers substantial stopping power, making it a popular choice for both law enforcement and civilian use. Its large magazine capacity, combined with the flexibility of the MOS system, positions the Glock 21 MOS as a versatile and powerful firearm suitable for a variety of shooting disciplines, including self-defense and tactical applications.
