The Promag Siga5 20-round magazine is a high-capacity option built for the Sig Sauer P226 in 9mm, giving shooters an extended ammunition supply without changing firearms. If you run a P226 for duty, sport shooting, or home defense, this blued steel magazine lets you load more rounds per magazine change—a genuine advantage on the range or in competition. Promag has been making aftermarket magazines for decades, and this model delivers straightforward reliability at a practical price point.
Constructed from blued steel, the Siga5 is durable and resistant to corrosion under normal use. The 20-round capacity is a substantial step up from the P226's standard 10 or 15-round magazines, making it particularly popular with recreational shooters and competitors who value fewer reloads during practice sessions or matches. The extended length does mean it may print visibly in a concealment context, so it's best suited to open carry, training, or range work.
Fit and feed are engineered specifically for the P226 platform, so you can count on consistent performance in your pistol. As with any high-capacity magazine, routine inspection and cleaning will keep it running smoothly over time.

| Model | Siga5 |
Yes—the Promag Siga5 is engineered specifically for the P226 in 9mm. It feeds and functions reliably in that platform.
The extended length accommodates the extra rounds, so the magazine will protrude noticeably beyond a standard 10 or 15-round mag. This makes it better suited to range work and competition than to concealed carry.
The Promag Siga5 is best suited to training, sport shooting, and range use where extended capacity is an advantage. The extended length and weight make it less practical for concealment or duty carry.
It's constructed from blued steel, which resists corrosion and provides solid durability for regular use.
