HK USP 9mm 31-Round Magazine

This is a polymer, factory OEM USP9 9mm 30-round extended magazine.
Built from lightweight polymer with high-tensile internal springs and an extended 30-round capacity, these magazines are designed to give you maximum firepower and reliability with your favorite HK® pistol. HK’s USP is one the most reliable, combat-ready handguns of the 20th Century—with innovative features and design that make it a relevant and reliable choice even now. Its 9mm variant offers reduced recoil and improved capacity without sacrificing any of the accuracy or precision of HK’s venerable USP. These extended magazines ship with stiff internal springs that may make them difficult to load the first few times. To break them in, try loading the magazine halfway and leaving it loaded for a few days. It can also be a good idea to pick up a magazine loader for quicker reloads and more trigger time.
