ProMag Magazine S&W P99, Walther P99, 9mm Luger 15-Round Steel Blue

The ProMag 15-round steel blue magazine for S&W P99/Walther P99 9mm Luger gives you a reliable, made-in-the-USA backup or primary mag for one of the most ergonomic duty-style pistols ever designed. Whether you're stocking spares for the range, building out your carry setup, or just want quality aftermarket capacity, this magazine delivers the dependability you need without the premium price tag of OEM.

Built from heat-treated blued steel, this mag resists corrosion and wear through heavy use. The internals are equally thoughtful: a follower lock-plate keeps rounds in perfect position, while a proprietary DuPont Zytel polymer base-plate and follower handle the mechanical stress of thousands of cycles. The spring is wound from chrome-silicon wire and heat-treated to maintain tension and reliability over time—no wimpy coils that lose their snap after a few years.

ProMag's reputation for no-nonsense American manufacturing shows in every detail. This is a straightforward, honest magazine: it loads, feeds, and runs. If you shoot a P99 or SW99 in 9mm, keeping a few of these on hand means you're never caught short at the range or in a defensive scenario.
