If you own a P226 in .40 S&W or .357 Sig, this is the magazine that came with your pistol. It's a straightforward, no-nonsense replacement built to the same specs as the factory original. The 12-round capacity strikes a practical balance for both shooting disciplines and self-defense use without running overly large in the hand.
This magazine is constructed from heat-treated steel with a blued finish that matches the look of quality P226s. The finish isn't just cosmetic, it's engineered to resist corrosion through regular use and exposure. Inside, you get a reliable steel wire spring paired with a polymer follower, the same components Sig uses for their factory magazines. These components are proven across thousands of P226s in military, law enforcement, and civilian hands over decades.
The flush-fit baseplate keeps the magazine snug to the grip without extending beyond it, which matters if you carry or want a clean look with your holster setup. It seats firmly in the magazine well and drops free when you release it, which is essential for fast reloads whether you're at the range or in a defensive situation. The witness holes on the side let you count your rounds on the fly without tilting the gun.
One of the practical advantages of the P226 platform is that .40 S&W and .357 Sig use the same frame and magazine. This mag feeds reliably with both calibers, so if you ever convert your barrel between the two, your magazines follow along without any swaps needed. It's one of those details that makes the P226 system appealing to folks who want flexibility without building a whole new gun.
Yes. This magazine is designed to feed both .40 S&W and .357 Sig interchangeably. The P226 uses the same magazine well for both calibers, so you can swap barrels between the two without changing magazines. It's one of the practical advantages of the P226 platform.
This is a factory original Sig Sauer magazine manufactured to the same specifications and tolerances as magazines that ship with new P226 pistols. It's built from the same materials using the same processes, guaranteeing proper fit and reliable feeding in your firearm.
Sig Sauer makes this magazine in 10-round and 15-round variants as well. The 12-round sits in the middle, offering a practical capacity for range work and duty carry without being too large or too small. Your choice depends on your use case and preference for magazine size and weight.
Keep it clean and dry between uses. Periodically unload it, wipe down the exterior, and check the spring tension. The follower and spring are durable, but if you notice feeding issues after extended use, replacement springs and followers are available. The blued finish will benefit from light oil applied occasionally to maintain corrosion resistance.
