Sig Sauer P226 .40 Auto / .357 SIG - 15 Round Extended Magazine

The Sig Sauer MAG-226-43-15 is the genuine factory OEM 15-round extended magazine for the legendary SIG Sauer P226 chambered in .40 Auto or .357 SIG. Delivering three additional rounds over the standard 12-round magazine, this extended factory magazine gives P226 owners maximum capacity without sacrificing the fit, reliability, or quality that has made the P226 one of the most trusted duty pistols on the planet.

The P226 is one of the most battle-tested service pistols in history, carried by Navy SEAL teams, federal law enforcement agencies, and military personnel worldwide across decades of hard use. This is the magazine built to match that standard.

Factory Original. Duty Grade Reliability.

This is a genuine Sig Sauer factory magazine, manufactured to the same precise specifications, tolerances, and materials as the original magazine your P226 shipped with. Every dimension is engineered to deliver a perfect fit in the P226 magazine well with zero wobble or excessive play, ensuring consistent cartridge alignment with the feed ramp for reliable chambering round after round.

Dual Caliber Versatility

One of the most valuable features of the P226 platform in .40 Auto and .357 SIG is that the same magazine serves both calibers with only a barrel swap required. The MAG-226-43-15 is fully compatible with both cartridges, making it the only extended magazine you need to cover both caliber configurations of your P226.

Note: this magazine is not compatible with P226X models.
