H&K USP9 Tactical.

A threaded barrel with an O-ring, match trigger with adjustable trigger stop, and adjustable target sights make this the ultimate 9 mm “spec ops” handgun. Like all full size HK USPs, the 9 mm Tactical uses a modified Browning type action with a special patented recoil reduction system. The USP recoil reduction system mitigates recoil effects on the pistol components and also lowers recoil forces felt by the shooter. By using a modular approach to internal components, the control lever function of the USP can be switched from the left to the right side of the pistol to accommodate left handed shooters. Like all USPs, the USP9 Tactical can be converted from one type of firing mode to another. This includes combination double action/single action modes, double action only (including HK’s acclaimed “Law Enforcement Modification”). Wellsuited for personal defense use and a wide variety of security and civilian/commercial applications, the USP9 Tactical can also be used with a variety of sound suppressors. Please note that use of suppressors can void Heckler & Koch’s limited lifetime warranty for commercial/civilian customers. The USP9 Tacticals are engineered with the famous long-term durability that make all HK products especially cost-effective when subjected to total life cycle cost analysis. The control lever has a positive stop and automatically returns to the “fire” position after decocking. The control lever, allows USPs to be safely carried “cocked and locked.” Rear target sight features micrometer adjustment for windage and elevation, front sight is high profile type for aiming over sound suppressors. Reinforced polymer frame. HK pioneered the use of composite materials in production handguns more than thirty-five years ago with the development of the VP70Z and P9S pistols. Threaded barrel with O-ring — an innovative design feature found on several HK pistols — the high temperature rubber O-ring seals and centers the barrel in the slide until unlocking of the barrel. The O-ring has a significant effect on accuracy, last 20,00 rounds, and can be replaced without tools in seconds. USP9 Tactical has polygonal barrel profiles made by HK’s famous cold-hammer forging process—ensuring increased barrel life and optimal accuracy. HK proprietary mounting rails allow lights and aimers to be installed on the USP series pistols and held securely in position. An industry standard or Picatinny rail adaptor can also be installed to enable a larger selection of accessories to be used. Improved match single-action and double-action trigger pull with adjustable trigger stop to eliminate overtravel.
