ProMag CZA4 Baby Eagle 20rd 9mm Magazine CZ-75/TZ-75 Blued Steel

The ProMag CZA4 Baby Eagle 20-round magazine extends capacity for CZ-75 and TZ-75 pistols without compromising reliability. This aftermarket magazine provides nearly double the standard capacity while maintaining the original grip profile and handling characteristics.

What Makes This Different

Unlike standard 10-round magazines, the CZA4 delivers 20 rounds of 9mm capacity through an extended body design that adds minimal length to the grip. The blued steel construction matches factory magazine durability while the extended baseplate provides positive grip during tactical reloads. Heat-treated steel components resist deformation under spring pressure, maintaining consistent feeding geometry through thousands of cycles.

Key Features

• 20-round capacity doubles standard magazine ammunition count
• Blued steel construction with corrosion-resistant finish
• Compatible with CZ-75, TZ-75, and Baby Eagle pistol variants
• Extended baseplate design enhances grip during magazine changes
• Heat-treated steel body maintains dimensional stability
• Chrome silicon spring provides consistent feeding pressure
• Anti-tilt follower design prevents ammunition binding

Range performance demonstrates reliable feeding across various 9mm ammunition weights from 115 to 147 grains. The extended capacity proves valuable for competitive shooting disciplines requiring higher round counts, while the steel construction withstands repeated loading and unloading cycles. Law enforcement and security professionals benefit from the increased ammunition capacity during extended duty periods.
