Promag Heca17 40Rd 9Mm Fits H&K Mp5/Ptr9 Black
$20.61
The ProMag HK MP5/PTR9 9mm magazine is a high-capacity 40-round option built for shooters who run HK MP5 platforms and their modern clones, including the PTR9. If you've got one of these rifles in your safe and you're tired of swapping magazines at the range or in the field, this is the kind of extended capacity that keeps you shooting longer between reloads—a solid choice for dedicated MP5 owners and PDW enthusiasts who want more rounds on tap.
The magazine body is molded from DuPont Zytel polymer, a material choice that brings natural corrosion resistance and real durability to the table. That matters when you're running through ammo in less-than-ideal conditions or storing magazines long-term. The reinforced feed lips are designed to reliably position each round as it feeds into the chamber, and the high-tensile chrome silicon wire spring pairs with an injection-molded polymer follower to keep the action smooth and jam-free, even as the magazine cycles through its full 40-round capacity.
ProMag backs this magazine with a lifetime warranty, reflecting confidence in the product's construction and real-world reliability. It's made in the USA, which matters to plenty of shooters who prefer domestically manufactured gear. Whether you're setting up a dedicated range gun, building out a patrol or training carbine, or simply want reliable backup magazines for your MP5 platform, this 40-rounder delivers the capacity and dependability you'd expect from a ProMag product.
