Description
When you own an HK, aftermarket magazines just feel like a compromise. This is the real deal: a genuine Heckler & Koch factory magazine for the P2000 and USP Compact chambered in .40 S&W, built on the same production line and to the same standards as the mag that shipped with your pistol. Twelve rounds of .40, no guessing, no fitment headaches.
The body is steel construction finished in black, paired with a high-tensile steel spring and a red polymer follower that makes it easy to confirm the mag is empty at a glance. The injection-molded polymer baseplate doubles as a finger rest, which gives you a fuller grip on a compact-sized pistol and makes stripping the mag more natural under any conditions. It also simplifies disassembly for cleaning. The whole package comes in at a very manageable weight that won't throw off your carry setup.
This mag is a straight drop-in for both the HK P2000 and the USP40 Compact. No modification, no persuasion needed. Whether you're building out a range bag with a few reliable spares or replacing a mag that's seen better days, this is the right part for the job. HK manufactures these in Germany to the same tolerances as the pistols themselves, which is exactly what you want when feeding .40 S&W through a gun you're depending on.

Frequently Asked Questions
Will this magazine work in both the HK P2000 and the USP40 Compact?
Yes, this magazine is designed to fit both the HK P2000 and the USP40 Compact chambered in .40 S&W. It's a direct drop-in fit for either pistol with no modifications required. Just make sure your pistol is in .40 S&W, as these models also come in other calibers with their own corresponding magazines.
Is this a genuine HK factory magazine or a third-party replacement?
This is a 100% genuine Heckler & Koch factory magazine, manufactured in Germany to the same specifications and tolerances as the original equipment magazines. MPN 50259085 is H&K's own part number, so you're getting the real thing, not a copy.
What does the extended floorplate do, and can I swap it out?
The extended floorplate on this magazine functions as a finger rest, giving you a slightly fuller grip on the compact-sized pistol and making mag changes smoother. It's injection-molded polymer and is designed to be user-removable for cleaning and maintenance. If you prefer a flush or lower-profile option, HK and third-party manufacturers offer alternative baseplates that are compatible.
Why is there a red follower in this magazine?
The red follower is a practical visual indicator. When the magazine is empty and the slide locks back, a quick glance into the chamber or at the mag well lets you confirm the gun is empty without any ambiguity. It's a small detail H&K includes that actually makes a real difference during training and administrative handling.
How many spare magazines should I pick up for range use or carry?
For range sessions, most people find that three or more magazines keeps things moving without constant reloading downtime. For carry purposes, at least one spare is a solid baseline, though many folks prefer two. Since these are factory mags built to last, stocking up makes sense rather than wearing out the one that came with your pistol.
