ProMag Sig Sauer Sig Pro .40 S&W 15-Round Blue Steel Magazine

The ProMag® Sig Sauer® Sig Pro .40 S&W 15-Round Blue Steel Magazine is an affordable, yet reliable alternative to Sig factory magazines, built to the same specs and tolerances for butter-smooth feeding and consistent operation at a fraction of the cost. The heat-treated steel body delivers exceptional strength and crush-proof performance, while the premium blued finish offers superior corrosion resistance for reliable field operation in virtually any environment. A heat-treated chrome silicon wire internal spring eliminates binding for smooth feeding operation with the durable, injection-molded polymer follower, and the removable floor plate allows for quick disassembly when maintenance and cleaning are required for added field reliability. Better yet, this magazine features precision-machined feed lips for a snug, wobble-free fit. Backed by ProMag’s legendary Lifetime Warranty. Made in USA.
