SIG SAUER P226 .40 S&W/.357 SIG 10-Round Magazine

SIG SAUER P226 .40 S&W/.357 SIG 10-Round Magazine

This SIG SAUER P226 magazine is a 10-round replacement magazine for P226 pistols chambered in .40 S&W or .357 SIG. Its steel construction, blued finish, and model-specific geometry make it suitable as a replacement for a worn magazine or as an additional magazine for training, range use, or a prepared spare-magazine rotation.

The exact manufacturer part number is MAG2264310, also commonly presented as MAG-226-43-10, and the UPC is 798681108602. These identifiers separate this version from P226 magazines built for 9mm and from higher-capacity .40 S&W/.357 SIG configurations. Buyers should verify the part number, pistol model, and chambering rather than selecting a magazine by appearance alone.

Designed for the P226 Caliber Family

This magazine is intended for the SIG SAUER P226 chambered in either .40 S&W or .357 SIG. Those cartridges share the magazine format used by this part number, while the 9mm P226 uses a different magazine. It is not intended as a universal SIG SAUER magazine and should not be assumed to fit P220, P229, SP2022, or other pistol families.

Proper model fit matters because the magazine body dimensions, catch location, feed lips, follower, and spring work together with the host pistol. A correctly matched, serviceable magazine supports positive seating, reliable cartridge presentation, and proper slide-lock operation after the final round.

Blued-Steel Body and 10-Round Capacity

The magazine uses a steel body with a blued finish and a detachable box-magazine design. Its 10-round capacity provides a compliant-capacity option in many regulated jurisdictions, subject to local law, and can also be useful for controlled drills or shooters who prefer a lower-capacity range magazine.

A durable steel body helps the magazine retain its shape through repeated loading and unloading. As with any working magazine, it should still be inspected periodically for dents, damaged feed lips, unusual follower movement, a loose baseplate, corrosion, or excessive fouling. A magazine is a critical part of a semi-automatic pistol’s feeding system, so worn or damaged examples should be removed from service.

A Practical Factory-Format Spare

Additional magazines make it easier to organize ammunition, rotate equipment, and spend more time practicing instead of repeatedly stopping to reload a single magazine. A dedicated spare also gives the owner a known replacement if a primary magazine becomes damaged or begins producing reliability problems.

Confirm that the pistol is a P226 chambered in .40 S&W or .357 SIG before purchase. Follow SIG SAUER’s instructions for loading, unloading, inspection, and maintenance. This package includes one magazine only; the firearm and ammunition are not included. Magazine-capacity laws vary, and the purchaser is responsible for confirming that this product may be possessed and received in the destination jurisdiction.
