ProMag SIGA9 32-Round Magazine 9mm Luger Sig P320 Blued Steel

The ProMag SIGA9 Standard magazine transforms your Sig P320 into a high-capacity platform with 32 rounds of 9mm Luger ammunition. This extended magazine eliminates frequent reloads during training sessions and competitive shooting events. Built with heat-treated blued steel construction, it delivers reliable feeding and ejection cycle after cycle.

What Makes This Different

Unlike standard 15-round factory magazines, the SIGA9 more than doubles your ammunition capacity without sacrificing reliability. The steel body construction resists deformation under stress, while the anti-tilt follower maintains consistent cartridge presentation. ProMag engineers this magazine to meet the feeding geometry specifications of the P320 platform, ensuring compatibility across all P320 variants including compact, carry, and full-size models.

Key Features

• 32-round capacity doubles standard magazine ammunition load
• Heat-treated blued steel body resists wear and corrosion
• Anti-tilt follower prevents feeding malfunctions and jams
• Compatible with all Sig P320 variants and configurations
• Chrome silicon spring maintains consistent tension over time

Range training becomes more efficient with fewer interruptions for reloading, allowing shooters to focus on fundamentals and accuracy development. Competition shooters benefit from extended strings of fire in practical shooting disciplines. The magazine functions reliably with standard pressure 9mm ammunition from 115-grain to 147-grain bullet weights. Law enforcement agencies appreciate the extended capacity for qualification courses and tactical training scenarios.
