Pro Mag Industries S&W SD9 Magazine Features This ProMag magazine is built specifically to fit the Smith and Wesson SD9 pistol holding 10 rounds of 9mm Luger for range use training or backup carry. The magazine body is constructed from heat-treated steel and finished in black oxide giving it resistance to corrosion and wear beyond what many polymer-bodied magazines offer. An injection-molded follower rides smoothly inside the body helping ensure the last round feeds as reliably as the first. The heat-treated chrome silicone spring is engineered to hold its tension over repeated loading and unloading cycles reducing the risk of feeding issues as the magazine ages. ProMag manufactures this magazine in the USA giving SD9 owners a domestically produced option for expanding their magazine supply. Adding a spare magazine is a straightforward way to reduce downtime at the range or provide a reliable backup for a primary carry magazine. Because it is purpose built for the SD9 it should insert and lock into the magazine well without any additional fitting. This ProMag magazine for the Smith and Wesson SD9 is available for sale at GrabAGun for shooters who want a dependable spare or replacement.
