The P226 has been a benchmark pistol for decades, and when you're running one, you want magazines that match that standard. This factory Sig Sauer 20-round magazine is built to the exact same specs and tolerances as the mag that came with your pistol. No guessing about fit, no feed issues, no drama.
The body is constructed from heat-treated blued steel, giving it solid corrosion resistance and long-term durability. Inside, a high-tensile music wire spring and an anti-tilt polymer follower work together to keep rounds feeding smoothly and consistently, even under rapid fire. The polymer follower, lock plate, and baseplate are molded from a DuPont Zytel-based material, which is tough, lightweight, and impact resistant.
One of the more practical features is the witness holes positioned at the 5, 10, 15, and 20-round marks along the side. A quick glance tells you exactly where you stand without having to drop the mag and count. Small detail, but it matters when you're in the middle of a range session or competition stage.
With five more rounds over the standard 15-round P226 magazine, this extended mag is a natural choice for anyone who wants to spend more time shooting and less time reloading. It seats and releases just like a factory mag should, and the extended baseplate gives you a little extra purchase on the grip during mag changes. Sig P226 owners who shoot regularly tend to pick up a few of these at a time, and it's easy to see why.
This magazine is made to fit the Sig Sauer P226 chambered in 9mm. It's a factory Sig Sauer product built to P226 specifications, so it's compatible with standard P226 9mm configurations. If you have a P226 variant like the X-Five or MK25, double-check your model before ordering, as some variants have their own dedicated magazines.
The standard P226 9mm factory magazine holds 15 rounds, so this 20-rounder does extend noticeably past the grip. The extended polymer baseplate gives you a bit more surface to grab during mag changes, which most people find helpful rather than a drawback. The overall loaded length of the magazine is approximately 8.4 inches.
This is a genuine factory Sig Sauer magazine under part number MAG-226-9-20. It's manufactured to Sig's own specifications using the same materials and tolerances as the OEM magazines. Sig does note that because they source from multiple manufacturers to their specs, there can be minor variations in stamping or finish color between production runs.
The magazine features side-facing witness holes at the 5, 10, 15, and 20-round marks. You can do a quick visual check while the magazine is still seated in the pistol to get a read on your round count. It's a simple feature, but genuinely useful during range sessions or competition.
Factory Sig Sauer magazines are generally reliable right out of the box and don't require a formal break-in. That said, it's always a good habit to function-test any new magazine before relying on it, running a full 20 rounds through to confirm everything cycles smoothly with your preferred ammunition.
