ProMag S&W SD9 9mm 10-Round Blued Steel Magazine

The ProMag S&W SD9 9mm 10-Round Blued Steel Magazine (ProMag part no. SMI 41) is a factory-fit replacement magazine built for the Smith & Wesson SD9 pistol chambered in 9mm Luger. ProMag machines the body from heat-treated steel and finishes it in a durable blued, black-oxide coating, then rounds out the build with an injection-molded polymer follower and a chrome-silicone wire spring for consistent, reliable feeding. It’s an easy way to add a spare magazine to your SD9 or replace a worn factory unit without hunting down OEM parts. Made in the USA, it’s built for range use, practice, and everyday backup capacity.
