The Sig Sauer Mag P229-1 9mm 10-round magazine is a factory direct-sourced replacement and backup mag for shooters running the P229-1 platform. If you carry, train, or compete with a P229-1 in 9mm, a second or third magazine is practical insurance—reload faster on the range, keep a loaded spare in your range bag, or maintain a redundant setup for duty or defensive use. This is a genuine Sig mag built to the company's specs, not a third-party clone.

The mag holds 10 rounds in a double-stack configuration and feeds reliably through the P229-1's magazine well. Steel body with a polymer baseplate keeps weight down while maintaining durability. The rear witness holes let you verify round count at a glance—useful for quick inventory checks before range sessions or training drills. All the practical details you'd expect from a factory OEM part.

Note that this magazine is designed exclusively for P229-1 framed pistols; it will not fit earlier P228 or P229 models without the -1 frame designation. Verify your pistol's marking before ordering. Minor variations in finish or stamping may occur due to Sig's multi-source manufacturing process, but function and reliability remain consistent.
