Description
This is the magazine your P226 9mm was born to run with. Sig Sauer's factory-original mag is built to their exacting standards using the same materials and processes as the OEM magazine that came from the factory. You get a steel body that takes the beating of heavy training and still keeps feeding reliably, paired with a heat-treated wire spring that feels confident under pressure.
Blued Steel Build That Goes the Distance
The all-steel construction holds up better than polymer alternatives, and the staggered feed design packs 10 rounds into a compact profile. The corrosion-resistant finish means this mag performs in field conditions without losing function. The flush-fit polymer baseplate seats smoothly and doesn't snag when you need a quick reload. A polymer follower keeps rounds feeding smooth and consistent through every shot.
Know Your Ammo Count at a Glance
Side-facing witness holes let you count remaining rounds without pulling the magazine out to check. For training, competition, or daily carry, you'll always know where you stand on ammunition. The magazine works with all standard P226 models including the P226X variants, and will even function in select other SIG models like the P228 and older P229 versions, though there may be slight looseness in those frames.
New magazines sometimes ship with stiff springs, which can make loading the final round feel tight at first. This isn't unusual and tends to ease up with use. The baseplate is straightforward to remove for cleaning and maintenance.

Frequently Asked Questions
Will this magazine work in other SIG Sauer pistols besides the P226?
This 9mm P226 magazine will function in the P228 and older P229 models, though you may notice slight side-to-side movement in those frames since their mag wells have slightly different dimensions. It's designed for optimal fit and performance in P226 pistols. The 10-round capacity remains consistent across all models.
Why is it hard to load all 10 rounds into my new magazine?
Factory-fresh magazines often ship with stiff springs because they're built to exact specifications and haven't been broken in yet. This is totally normal. After a few loadings and unloadings, the spring will loosen up slightly and loading becomes easier. If you're loading by hand, a magazine loader can help reduce the effort.
What do those holes on the side of the magazine do?
The witness holes (also called round count windows) are positioned along the side of the magazine to let you see how many rounds you have left loaded. You can count them at a glance without removing the magazine from your P226, making it quick and easy to track your ammunition during training or competition.
Is this a factory original magazine or an aftermarket copy?
This is a genuine factory Sig Sauer magazine manufactured to the same exacting specifications and tolerances as the original magazine that comes with a new P226. It uses identical materials and construction methods, guaranteeing optimal fit and reliable feeding in your pistol.
