Mec-Gar Sig Sauer Pistol Magazines

Mec-Gar SIG Sauer pistol magazines are reliable replacement magazines built for compatible SIG Sauer P226, P228, P229, P229-1, Pro 2009, and Pro 2022 pistols. Available in 9mm Luger, .40 S&W, and .357 SIG configurations, these magazines give shooters dependable spare or replacement options for range use, training, competition, and defensive carry where legal.

Each magazine is built with a heat-treated carbon steel tube, high-tensile music wire spring, and high-impact polymer follower for smooth feeding and long service life. Select variants feature Blued or Nickel finishes, while Anti-Friction coated models are designed for easier loading, reduced friction, improved corrosion resistance, and enhanced performance under repeated use.

Choose the correct variant by firearm model, caliber, capacity, finish, and floorplate style before purchase. Magazine only; firearm sold separately.
