ProMag SIG19 10-Round Magazine 9mm Luger Sig P290 Blued Steel

The ProMag SIG19 magazine delivers reliable feeding and consistent performance for Sig Sauer P290 pistols. This 10-round capacity magazine meets restricted state requirements while maintaining the feeding reliability that duty and concealed carry applications demand.

What Makes This Different

Unlike polymer alternatives, the blued steel construction provides enhanced durability and resistance to deformation under stress. The magazine features heat-treated steel construction that maintains dimensional stability through thousands of loading cycles. ProMag's manufacturing process ensures consistent follower tension and spring compression for reliable chambering across various 9mm Luger ammunition weights.

Key Features

• 10-round capacity compliant with restricted state regulations
• Heat-treated blued steel body resists corrosion and wear
• Precision-engineered follower ensures smooth ammunition feeding
• High-tensile spring maintains consistent pressure through extended use
• Drop-free design allows rapid magazine changes
• Witness holes provide visual round count verification
• Compatible exclusively with Sig Sauer P290 pistol platform

Field testing demonstrates consistent cycling with standard pressure 9mm ammunition ranging from 115-grain to 147-grain bullet weights. The magazine functions reliably in both concealed carry scenarios and range training environments. Temperature cycling from -10°F to 140°F shows no degradation in feeding performance or spring tension.
