USP Series

Polymer Frame

All USPs use a fiber-reinforced polymer frame stiffened by stainless steel inserts at areas subject to stress and friction. HK pioneered this use of polymer materials in the production of handguns more than 30 years ago.

Control Lever

The USP control lever, a combination safety and decocking lever, is frame mounted and quickly accessible, unlike the slide-mounted safeties common on many semi-automatic pistols.

Recoil Reduction

Using a modified Browning-type action with a special patented recoil reduction system, the USP recoil reduction system reduces recoil effects on pistol components and also lowers the recoil forces felt by the shooter.

Trigger Varients

This includes combination double-action and single-action (DA/SA) modes and double action only (DAO) LEM modes. The USP is available in nine trigger/firing mode configurations and three calibers. 9mm, .40 S&W and .45 ACP.

Specialized USP Models

Specialized models of the USP include threaded barrel tactical variants and a long slide Expert model ideal for competitive shooting and precision handgun applications. All specialized models include a match grade trigger, match grade sights with elevation and windage adjustment, and an O-ring barrel for optimal barrel-to-slide lockup. The USP Tactical models include threaded barrels for mounting an optional sound suppressor. Accessory magazine jet funnels are also available for 9 mm and .40 S&W USP Tacticals and USP Expert models. Availability on some USP Specialized models often is limited.
