MEC-GAR Sig Sauer P229 Handgun Magazine .40S&W / .357 Sig HT AFC Steel 14/rd

The MEC-GAR Sig Sauer P229 Handgun Magazine in .40 S&W / .357 Sig is a high-capacity steel magazine purpose-built to extend the ammunition carrying capacity of the P229 platform. With 14-round capacity and the integrated high-tensile AFC (Anti-Friction Coating) steel construction, this magazine delivers reliable feeding and extended firepower for duty and training applications where standard-capacity magazines fall short.

Built from certified AISI 1010 carbon steel, the magazine undergoes rigorous material testing for tensile strength and elongation rate before production acceptance—a hallmark of Mec-Gar's engineering standards. The redesigned tube improves functionality and cartridge alignment, ensuring consistent performance across both .40 S&W and .357 Sig chamberings. At only 5/8" longer than flush-fit alternatives, the magazine maintains a compact profile without the capacity penalty, making it suitable for duty rigs and practical shooting disciplines where magazine visibility and holster fit are operational considerations.

This magazine addresses the needs of law enforcement personnel, competitive shooters, and defensive carriers who depend on the P229 platform. The 14-round capacity with a compact footprint makes it ideal for tactical training scenarios, duty rotation, and range work where higher round counts reduce reload frequency. The steel construction and proven Mec-Gar reputation for durability make this a reliable choice for those who demand consistent feeding and longevity from their duty magazines.

The P229 remains one of the most widely issued and trusted duty platforms in North America, and aftermarket magazine options that deliver verifiable performance standards are essential for operators who maintain multiple duty guns or high-round-count training regimens. Mec-Gar magazines have long been specified as OEM alternatives and remain a cornerstone of professional armorer and department inventory decisions.
