SIG SAUER P226-X LEGION 9mm 18-Round Magazine

The SIG SAUER P226-X LEGION 18-round magazine is a factory replacement magazine built for 9mm P226-series pistols. It combines an 18-round capacity with a flush-fit profile for the P226-X LEGION line, making it a practical choice for replacing a worn magazine, adding a spare for range use, or keeping matching factory equipment with a compatible pistol. This listing is for SIG SAUER manufacturer part number 8901991, UPC 798681732296.

Compatible P226 Models

SIG SAUER lists this magazine for 9mm P226 and P226-X pistols, including the P226-X Carry. The flush-fit baseplate is specifically shaped for the P226-X LEGION line while maintaining compatibility with the broader 9mm P226 family. Because generations, grip configurations, and aftermarket components can vary, confirm your pistol model and caliber before ordering.

• Caliber: 9mm Luger
• Capacity: 18 rounds
• Models: P226, P226-X, and P226-X Carry in 9mm
• Fit: Flush-fit design for the P226-X LEGION line

Factory Construction and Features

The double-stack magazine uses a steel body with a black oxide finish and a black polymer baseplate. Side witness holes provide a quick visual reference when checking the approximate number of cartridges in the magazine. As a genuine SIG SAUER replacement magazine, it is manufactured to SIG specifications for the listed pistols.

SIG notes that its magazines may be sourced from more than one manufacturer and made to the company’s specifications. For that reason, minor differences in stamping or finish color may occur, and product images may not show every small production variation. These cosmetic differences do not change the listed 9mm chambering, 18-round capacity, or intended model compatibility.

Useful for Training and Spare-Magazine Rotation

An additional factory magazine helps keep range sessions moving and makes it easier to rotate magazines during routine practice. The 18-round capacity offers one additional round compared with a standard 17-round configuration while retaining the P226-X LEGION flush-fit form. Side witness holes also make administrative checks more convenient before and after training.

For dependable use, inspect magazines periodically for damage, excessive fouling, or unusual wear. Keep the magazine body and follower clean and dry, and follow the firearm manufacturer’s instructions for loading, unloading, maintenance, and safe handling. Do not modify the feed lips, body, spring, follower, or baseplate.

Ordering Notes

Magazine-capacity laws and shipping restrictions vary by state and locality. Confirm that an 18-round magazine may be lawfully purchased, possessed, and delivered in your area before ordering. This item is a magazine only; firearm and ammunition are not included.
