SIG SAUER P226 .40 S&W/.357 SIG 15-Round Magazine

SIG SAUER P226 .40 S&W/.357 SIG 15-Round Magazine

This factory SIG SAUER magazine is designed for compatible P226 pistols chambered in .40 S&W or .357 SIG. It holds fifteen rounds and uses a dark-finished steel body, providing a model-specific spare or replacement for training, range use, duty-magazine rotation, or restoring a P226 setup with the correct factory configuration.

Exact P226 .40/.357 Compatibility

The .40 S&W and .357 SIG P226 variants share the magazine configuration represented by this exact model. It is not intended for a P226 chambered in 9mm, and it should not be selected for a different SIG SAUER pistol solely because the magazine looks similar. Confirm the pistol model, chambering, capacity, and part number before ordering.

Fifteen-Round Capacity

The magazine provides a fifteen-round capacity for compatible P226 .40 S&W and .357 SIG pistols. Keeping multiple properly matched magazines available can reduce loading interruptions during practice and help owners rotate equipment rather than repeatedly using a single magazine. It also makes diagnosis easier: if a problem consistently follows one numbered magazine, that unit can be isolated for inspection.

Steel Body with Dark Finish

The rigid steel body has a blue-black finish suited to the appearance of many P226 configurations. As with any working pistol magazine, routine inspection is important. Check the body and feed lips for damage, verify that the follower moves freely, and monitor the spring for consistent tension. Keep the interior clear of dust and fouling, and avoid excessive lubricant that can trap debris.

Verify the Model and Local Requirements

Before purchase, compare these specifications with the markings on the pistol and an existing factory magazine. This magazine is for the P226 .40 S&W/.357 SIG platform and is not a universal P226 magazine. Its fifteen-round capacity may be restricted in some jurisdictions, so customers should confirm current state and local requirements before ordering or possessing it.

Loading and Function Testing

Load only ammunition matching the firearm’s chambering. Although the magazine supports both listed calibers, the pistol itself must be chambered for the ammunition being used. Test the magazine with the individual firearm in a safe range environment before relying on it for important use. New springs may feel firm at first; use controlled pressure rather than forcing cartridges.

Do not bend the feed lips, cut the spring, or alter the body to change fit or capacity. If the magazine does not seat, lock, feed, or release normally, unload the firearm and magazine and consult the P226 owner’s manual or a qualified armorer.

With exact P226 fit, fifteen-round capacity, dual .40 S&W/.357 SIG compatibility, and factory SIG SAUER construction, this magazine is a straightforward addition to a properly configured P226 magazine rotation.
