The ProMag S&W 39 9mm Luger 8-round steel blue magazine is a single-stack replacement or backup mag for Smith & Wesson Model 39 pistols. If you shoot a classic S&W 39 for sport, collection, or occasional carry, reliable ammunition storage matters—and factory magazines don't last forever. This ProMag option gives you a durable aftermarket alternative built to the same single-stack profile as your pistol's original specs.
Construction is straightforward and proven: heat-treated blued steel for the body, a proprietary DuPont Zytel-based polymer follower that won't wear or warp, and a chrome-silicon wire spring that's heat-treated for consistent tension and feeding. The blued finish matches the aesthetic of vintage and classic S&W pistols and resists light corrosion in typical storage and range conditions. It's made in the U.S.A., so you're supporting domestic manufacturing.
At 8 rounds, this magazine fills the standard capacity for the Model 39—no surprises, no compression. Load it, verify function with your own pistol before relying on it in any serious role, and keep a spare or two on hand. Whether you're a collector keeping an old S&W 39 running, a shooter who wants extra magazines without factory pricing, or someone building a backup supply, a reliable spare mag is one of the simplest upgrades you can make.
