Triggerfiring mode conversion can only be made by an HK certified armorer

DA/SA with "safe" position and control lever (manual safety/decocking lever) on left side of frame À DA/SA with "safe" position and control lever (manual safety/decocking lever) on right side of frame

Variants and À allow the user to carry the pistol in a single-action mode (cocked and locked) with the control lever/manual safety engaged. This same pistol, without modification, can be carried in double-action mode, with

or without the control lever/manual safety engaged.

A DA/SA without "safe" position with control lever (decocking lever) on the left side of frame o DA/SA without "safe" position with control lever (decocking lever) on the right side of frame

Variants A and o provides the user with a frame-mounted decocking lever that does not have the "safe" position. This combination only allows the hammer to be lowered from SA position to DA position. It does not provide the "safe" position to prevent the pistol from firing when the trigger is pulled.

a DA-Only with "safe" position and control lever (manual safety) on the left side of frame re DA-Only with "safe" position and control lever (manual safety) on the right side of frame - DA-Only without control lever (no safety/decocking lever)

For the DA-Only user, variants a , re , and - of the USP operate as double action only pistols with the hammer always returning to the DA position (forward) after each shot is fired. To fire each shot, the trigger must be pulled through the smooth DA trigger pull. Variants a and œ have a manual safety lever (control lever). No control lever is provided on variant -.

œ DA/SA with "safe" position and control lever (manual safety) on the left side of frame 0 DA/SA with "safe" position and control lever (manual safety) on the right side of frame

Variants " and " allow the user to carry the pistol in a single-action mode (cocked and locked) with the manual safety engaged. Unlike variants and À, the control lever cannot be used to decock the hammer. These variants are the ideal choice for users who prefer shooting the pistol in the SA mode with the thumb placed on top of the control lever/manual safety. Variants " and " also use a spurred hammer, unlike other USP Compact variants.

This same pistol, without modification, can be carried in double-action mode, with or without the control lever/manual safety engaged, and provides second primer strike ability to single-action shooters.

Due to this innovative design approach, it is possible to convert a USP Compact into any one of the listed variants. Changing the trigger/firing mode of the pistol is

accomplished by installing a different set of components.

This unique design allows the HK Compact Universal Self-loading Pistol to be configured for a variety of purposes depending on the requirements of the user, without having to purchase a new pistol.

Fire Modes and Control Functions by Variant

In addition to a wide selection of trigger/firing modes, all USP Compacts have an ambidextrous magazine release lever which is shielded from inadvertent actuation by the flared trigger guard. The magazine release lever can be pressed with the all USP Compacts have an ambidextrous magazine release lever which is shielded from inadvertent actuation by the flared trigger guard. The magazine release lever can be pressed with the thumb or index finger of the firing hand, in most cases without adjusting the firing grip.

Low profile 3-dot sights, adjustable for windage and elevation, are standard on the USP Compact. Optional tritium sights are also available.

The USP Compact uses metal magazines to keep grip size to a minimum. These magazines have a series of viewing holes on the back side for counting the cartridges remaining inside.

Two different interchangeable floor plates are available for the magazines of the USP Compact. A standard flat floor plate and an extended magazine floor plate with a finger extension provide a choice of grip options with each pistol. Magazine floor plates can be easily removed and changed without tools during disassembly.

The extended slide release is positioned to allow easy actuation without adjustment of the grip of the shooting hand. Another useful feature is the absence of a

trigger is pressed (with the control lever in the FIRE position if applicable).

To reduce barrel wear, all USP Compacts have polygonal cold hammer-forged barrels. This feature not only ensures longer barrel life and easier bore cleaning, but produces a better gas seal behind the bullet for increased muzzle velocity.

The HK USP Compact, like the large frame USP, is an extremely safe firearm, with no less than four safety features, some passive and some active in nature. Simple to field strip and maintain, the USP Compact is a reliable and trouble-free pistol.

An abbreviated set of universal mounting grooves for installing accessories is molded in the polymer frame of the USP Compact. These grooves allow a variety of accessories and targeting devices, such as the Mark II
