The Mec-Gar MGP22815B delivers reliable 15-round capacity for Sig Sauer P228 and P229 pistols with factory-specification performance. This blued steel magazine maintains the original equipment manufacturer standards while providing shooters with additional ammunition capacity for extended training sessions and duty use.

What Makes This Different

Mec-Gar manufactures magazines for over 90% of European pistol makers, including original equipment for Sig Sauer. The MGP22815B uses the same tooling and quality control processes as factory magazines, ensuring identical feed geometry and spring tension. Unlike aftermarket alternatives that may cause feeding issues, this magazine maintains the precise tolerances required for consistent chambering across all 9mm Luger ammunition types.
