ProMag Sig Sauer Sig Pro .40 S&W 10-Round Blue Steel Magazine

Designed to deliver factory-like field performance without breaking the bank, the ProMag® Sig Sauer® Pro .40 S&W 10-Round Blue Steel Magazine is an affordable aftermarket pistol magazine, manufactured to the same tolerances as factory magazines, but at a fraction of the cost. The heat-treated steel body features a corrosion-resistant black oxide finish for lasting durability, while the heat-treated chrome silicon wire internal spring eliminates binding, ensuring the injection-molded polymer follower operates flawlessly for reliable feeding. Better yet, this centerfire pistol magazine comes equipped with a shock-resistant DuPont® Zytel™ polymer floor plate for improved shock and corrosion resistance. If that’s not enough, this American-made magazine is backed by ProMag’s legendary lifetime warranty! Order today. Made in USA.
