ProMag Industries Magazine, 9MM, 17 Rounds, Fits H&K VP9, Steel, Blued Finish HEC-A15 HECA15

In a market dominated by polymer-frame, double-stack, duty-size 9mm handguns, one of the most popular options out there is the Heckler & Koch VP9, which provides shooters with a few enhancements over other options on the market, such as its enhanced trigger. Practice makes perfect with these guns, though, and this 17-round, all-steel magazine provides an additional loaded mag for training and daily carry.

Each HK VP9 steel magazine has a carbon-steel magazine body that's heat-treated and finished with a black-oxide treatment. This steel body provides the durability that today's handgun owners are looking for in a carry-ready magazine.

Inside the HK VP9 steel magazine, consumers will find a magazine spring that's made from heat-treated chrome-silicon wire. This spring is topped by an injection-molded follower. Each of these mags is made in the USA.
