Description
This is genuine HK factory magazine designed for the MP7A1 and MP7A2 submachine guns chambered in 4.6x30mm. The 40-round capacity fits inside the weapon's compact pistol grip, comparing in size to a standard 30-round 9x19mm magazine. It's built with steel construction paired with an anti-tilt polymer follower that prevents misfeeding during rapid fire.
Steel Construction Meets Compact Design
The magazine body is all steel, giving it the durability to handle rough field conditions and repeated use without degradation. The anti-tilt follower ensures rounds feed smoothly and reliably, whether you're running single shots or putting rounds downrange rapidly. The compact footprint of this 40-rounder makes it practical for the MP7A1's ergonomic design, since the magazine well is integrated into the pistol grip.
Made in Germany by Heckler & Koch
This is factory ammunition storage, built to the same specifications as the magazines that ship with the weapons system. German manufacturing means precise tolerances and quality control that matches the MP7A1 platform. Whether you're running training drills, tactical operations, or extended range sessions, factory H&K magazines like this one eliminate the guesswork about feeding reliability.

Frequently Asked Questions
Will this 40-round MP7A1 magazine work with the MP7A2?
Yes, this magazine is compatible with both the MP7A1 and MP7A2 submachine guns. The 40-round design fits both platforms without any modification or fitment issues.
How does the 40-round magazine compare in size to the 20-round version?
The 40-round magazine is larger vertically but remains compact overall because of the small diameter of the 4.6x30mm cartridge. It compares in size to a standard 30-round 9x19mm magazine, making it practical for the MP7A1's design without becoming unwieldy.
What is the anti-tilt polymer follower and why does it matter?
The anti-tilt follower prevents the rounds from tilting or binding as they feed from the magazine, which means consistent, reliable feeding even under rapid fire. This design detail is what separates a solid OEM magazine from cheaper alternatives that can cause feeding problems.
Is this an OEM magazine from Heckler & Koch?
Yes, this is a factory HK magazine manufactured in Germany to the same specifications as magazines shipped with the MP7A1 and MP7A2 weapon systems. It meets the durability and feeding standards expected from genuine factory ammunition storage.
