ProMag BRO03 10-Round Magazine 22 LR Browning Buck Mark Blued Steel

The ProMag BRO03 delivers reliable feeding and extended capacity for Browning Buck Mark pistols, transforming your shooting sessions with consistent performance. This aftermarket magazine provides shooters with enhanced ammunition capacity while maintaining the compact profile essential for competitive shooting and training.

What Makes This Different

Unlike factory magazines that typically hold fewer rounds, the BRO03 offers 10-round capacity in a steel construction that withstands repeated use. The blued steel finish resists corrosion while providing the durability needed for high-volume shooting. Heat-treated steel construction ensures dimensional stability under stress, preventing feed lip deformation that plagues polymer alternatives.

Key Features

• 10-round capacity increases shooting time between reloads
• Blued carbon steel construction resists wear and corrosion
• Heat-treated feed lips maintain proper geometry over time
• Drop-free design enables rapid magazine changes
• Compatible with all Browning Buck Mark pistol variants
• Chrome silicon spring provides consistent tension
• Witness holes allow quick round count verification

Range testing demonstrates reliable feeding with standard velocity and high-velocity 22 LR ammunition. Competition shooters benefit from the extended capacity during rapid-fire stages, while training applications see improved efficiency with fewer interruptions. The steel construction handles thousands of loading cycles without spring fatigue or dimensional changes that affect reliability.
