SIG SAUER P229 Legacy 9mm 15-Round Magazine

SIG SAUER P229 Legacy 9mm 15-Round Magazine

This SIG SAUER factory replacement magazine is made for legacy P229 pistols chambered in 9mm. It provides a 15-round capacity in the original NON-1 magazine format, making it the correct choice for owners maintaining or adding magazines to an earlier-production P229.

This listing is for SIG SAUER manufacturer part number MAG-229-9-15, UPC 798681475056. SIG identifies it as a black, 15-round magazine for P229 NON-1 pistols.

Critical Compatibility Notice

This magazine is for legacy P229 NON-1 pistols and is not the magazine for P229-1 or E2 models. The later P229-1/E2 configuration uses a different SIG SAUER part number. Confirm the marking and configuration of your pistol and existing magazines before ordering. A matching caliber and capacity alone do not guarantee fit between the legacy and updated P229 magazine systems.

Factory Fit for Earlier P229 Pistols

Factory magazines are built around the firearm’s original magazine-well dimensions, catch location, feed geometry, and slide-lock relationship. For a compatible legacy P229, this magazine is intended to seat correctly, present cartridges at the proper angle, and work with the pistol’s controls as designed. The 15-round capacity provides a full-size ammunition supply while retaining the format intended for the older P229 frame.

Inspection and Use

Before loading, verify that the pistol is a compatible legacy P229 and that the magazine locks into place without being forced. Inspect the body, feed-lip area, follower, spring tension, and floorplate for damage or unusual wear. Load only factory-specification 9mm Luger ammunition and never exceed the stated 15-round capacity.

With the firearm unloaded and pointed in a safe direction, confirm that the magazine inserts, locks, releases, and drops free as expected. Function-check it before relying on it for defensive use. New magazines may feel firm when loaded to capacity; use steady pressure rather than striking or forcing cartridges into place.

Care and Maintenance

Keep the magazine clean and dry, especially around the follower path and feed lips. Powder residue, dust, lint, and grit can affect movement or cartridge presentation. Follow SIG SAUER’s guidance before disassembly, avoid excessive lubricant that can attract debris, and replace a magazine if it is cracked, distorted, heavily corroded, or no longer retains the floorplate securely.

Legal Considerations

Magazine-capacity laws vary by jurisdiction. Buyers are responsible for confirming that a 15-round magazine may be purchased, possessed, and delivered at the destination. Store or carrier restrictions may also apply.

For a legacy 9mm P229 owner, MAG-229-9-15 provides the correct factory 15-round NON-1 magazine configuration without confusing it with the later P229-1/E2 version.
