This is the HK USP-FS .45 ACP 10-round magazine.

If you’re stuck in a compliant state and need some spare magazines for your HK USP45, you’re in the right place! 

This nitride-coated steel magazine provides a superior level of durability for all of your tactical needs. Inside, you’ll find an anti-tilt polymer follower and high-quality steel spring that work together to keep your USP45 running without so much as a hiccup. 

On the back of the magazine are precision-cut witness holes and on the bottom is a removable floor plate. There is virtually nothing left to be desired except for a few more rounds! Whether you’re competing, hitting the range, or concealed carrying, this magazine will serve you well. 

At only ten rounds, you might as well grab a few!
