Sig Sauer MAG229910 P228/P229 10-Round 9mm Magazine Blued Steel

The Sig Sauer MAG229910 delivers reliable feeding and consistent performance for P228 and P229 pistols in 9mm Luger. This factory magazine maintains the tight tolerances and quality control standards that professional shooters and law enforcement depend on. Built with blued steel construction, it provides durability that aftermarket alternatives often lack.

What Makes This Different

Factory Sig Sauer magazines undergo rigorous testing and quality control that generic alternatives skip. The MAG229910 features precision-formed steel body construction with witness holes for quick round counting. Unlike polymer magazines that can crack under stress, the steel body maintains structural integrity through thousands of loading cycles. The 10-round capacity meets restricted state requirements while maintaining reliable function.

Key Features

• Factory Sig Sauer construction ensures perfect fit and function
• Blued steel body resists corrosion and maintains dimensional stability
• 10-round capacity complies with restricted state regulations
• Witness holes allow quick visual round count verification
• Compatible with P228 and P229 pistols in 9mm Luger
• Heat-treated steel spring provides consistent tension
• Anti-tilt follower design prevents feeding malfunctions

The MAG229910 performs reliably across temperature extremes and extended use cycles. Law enforcement agencies specify factory magazines for duty weapons because aftermarket options introduce variables that can cause malfunctions during critical situations. The steel construction handles repeated dropping on concrete and maintains feed lip geometry that polymer magazines often lose over time.
