Mec-Gar Sig P229 .40 S&W 14-Round Steel Anti-Friction Magazine - Black

The Mec-Gar Sig P229 .40 S&W 14-round magazine is a high-capacity steel magazine purpose-built for shooters who want more rounds between reloads without significantly altering their carry profile. Mec-Gar manufactures to exacting material standards—this magazine is formed from certified AISI 1010 carbon steel and heat-treated for durability, giving it the strength and longevity serious shooters expect from a duty or range-focused magazine. If you're running a P229 in .40 S&W and want the flexibility of a plus-two capacity upgrade, this is the straightforward choice.

The 14-round capacity fits P229 owners looking for additional firepower without the bulk of a full-sized platform magazine. At just 5/8" longer than flush-fit mags, the added length is minimal—you'll keep the handling characteristics of your gun while gaining meaningful capacity. The anti-friction coating on the feed lips and interior surfaces makes loading smooth and reduces wear; it also provides solid corrosion resistance, important if you're carrying or storing in variable conditions. Mec-Gar's attention to tensile strength and chemical composition in raw materials before production means you're getting a magazine designed to function reliably through thousands of rounds.

Whether you're building a competition setup, running range drills, or simply want backup magazines with more capacity, this Mec-Gar mag delivers proven reliability and American manufacturing. The interlinked internal components are engineered to stay reliable across extended service life.
