Glock 10mm 8.9" 31-Round

The B&T Firearms BT500167ABCT Glock 10mm 8.9" 31-Round platform is purpose-built for tactical professionals and serious defensive shooters who demand a high-capacity, reliable platform in one of the most potent duty calibers available. This compact rifle-length upper receiver system addresses a critical gap in the market: delivering 10mm Auto's proven stopping power and deep magazine capacity in a form factor optimized for close-quarters and intermediate-range engagements. Whether deployed in law enforcement, military support, or advanced civilian defensive roles, this system combines proven ergonomics with magazine-fed firepower that exceeds standard pistol-caliber carbine capacity.

The 8.9-inch barrel length maximizes velocity retention while maintaining portability—critical for vehicle operations, building entries, and tactical transitions. The 31-round magazine capacity provides sustained firepower and reduces reload frequency during high-stress scenarios, a decisive advantage over standard 15–17-round platforms. B&T's engineering delivers consistent cycling and reliability across the spectrum of 10mm ammunition, from standard-pressure loadings to premium defensive and hunting rounds. At 9.09 pounds, this system balances control and maneuverability without sacrificing structural integrity or recoil management, enabling rapid target acquisition and accurate follow-up shots.

This platform is ideal for tactical teams, firearms instructors, and defensive shooters who prioritize lethality and practical magazine capacity over minimal weight. The 10mm chambering works with any standard 10mm Auto ammunition, offering flexibility in load selection—whether duty rounds, specialized barrier-blind ammunition, or hunting applications. Operators familiar with Glock ergonomics and controls will recognize the intuitive interface, reducing transition time and training overhead. Proper eye protection and hearing protection are mandatory for all range use and deployment.
