Built for power, reliability, and modern adaptability, the Glock G21 Gen5 MOS delivers full-size performance in a proven .45 ACP platform. Designed for duty, defense, and range use, this pistol offers strong stopping power combined with Glock's trusted durability and ergonomic improvements.

The 4.61" Glock Marksman Barrel (GMB) enhances accuracy with improved rifling and crown design, while the durable black nDLC finish on the slide and barrel provides superior resistance to wear and corrosion.
