Frequently Asked Questions
Will this magazine work in both the HK USP and the MK23?
Yes. This H&K factory magazine is designed to be compatible with both the HK USP and the HK MK23 pistols chambered in .45 ACP. Because it is manufactured to strict OEM tolerances, you can expect a precise fit and reliable feeding in either platform without modification.
What does "10-round capacity / 12-round body" mean?
The magazine body is physically sized to hold 12 rounds, but it has been blocked at the factory to limit capacity to 10 rounds in order to comply with California's magazine capacity restrictions. This means you get the structural integrity and ergonomics of the full-size magazine while remaining fully legal for purchase and use in California.
Is this a genuine factory H&K magazine or an aftermarket product?
This is a genuine, factory-original Heckler & Koch magazine manufactured to H&K's own specifications and quality standards. Unlike aftermarket alternatives, OEM H&K magazines are built with the exact materials, tolerances, and quality control measures used in H&K's production firearms, making them the most reliable choice for your USP or MK23.
