Sig Sauer P229 .40 S&W / .357 Sig 10-Round Blued Steel Magazine

The Sig Sauer P229 factory magazine is a genuine OEM 10-round detachable box magazine built for the .40 S&W and .357 Sig chamberings. Constructed from durable blued steel with a steel wire spring and a polymer follower, this magazine delivers reliable feeding and smooth lock-up in P229 pistols and is also compatible with the P228.

Sig Sauer's P229 magazines are engineered to factory specifications for consistent performance. The blued finish provides corrosion resistance, while the flush-fit design keeps the magazine profile low for comfortable carry and easy reinsertion. With a 10-round capacity, this magazine is well-suited for range use, training, and everyday carry in jurisdictions with standard capacity limits.

Whether you shoot .40 S&W or .357 Sig, this dual-caliber magazine functions in either chambering thanks to Sig Sauer's shared magazine profile across these calibers. Replace a lost or worn magazine with a factory original to keep your P229 running at its best.
