ProMag BER04 Magazine 7rd 22 LR Beretta 21A Bobcat Steel

The ProMag BER04 magazine delivers reliable feeding for the Beretta 21A Bobcat with enhanced steel construction that outlasts factory magazines. This 7-round magazine addresses common feeding issues found in original equipment magazines while maintaining proper fit and function.

What Makes This Different

The BER04 features heat-treated steel construction versus the lighter materials used in many factory magazines. The spring tension maintains consistent feeding pressure across all seven rounds, reducing the feeding failures that plague worn factory magazines. ProMag engineers the follower geometry specifically for the 22 LR cartridge profile, ensuring smooth chambering even with various bullet weights from 30 to 40 grains.

Key Features

• Heat-treated steel body withstands repeated loading cycles
• Chrome silicon spring maintains tension through 10,000+ loading cycles
• Precision-machined follower designed for 22 LR cartridge geometry
• Black oxide finish resists corrosion and wear
• Drop-free design ensures reliable magazine changes
• Fits all Beretta 21A Bobcat pistols without modification
• 7-round capacity matches factory specifications

The steel construction handles the rapid cycling common in competitive shooting and training scenarios. The magazine functions reliably with standard velocity, high velocity, and hyper velocity 22 LR ammunition. The black oxide finish maintains its appearance through thousands of insertion and extraction cycles while resisting moisture and fingerprint oils.
