The Heckler & Koch USP (Universelle Selbstladepistole, or "Universal Self-loading Pistol") is a semi-automatic pistol designed by the German arms manufacturer Heckler & Koch.
The first USP Compact models appeared in 1994. These are scaled-down USPs, and are available in all the same cartridges as the full size version, and additionally the .357 SIG. Due to the smaller size of the frame, magazines for the Compact variant may have a handgrip extension to better accommodate the shooter's hand. Standard flat floorplates are also available for the USP Compact magazines. The USP Compact comes standard with a bobbed hammer equipped with a flat rubber external thumb grip. This reduces possible snag from the hammer on a holster or clothing while the pistol is being drawn, but still allows the USP Compact to be cocked from a decocked position even in the absence of a spurred hammer. This can be done since decocking the weapon does not fully drop the hammer, leaving it in a somewhat "half-cocked" state. USP Compact models lack the mechanical recoil reduction system of the larger full sized USP pistols. Instead, a more compact recoil buffering system is composed of a polymer bushing, around the captive recoil spring, which is designed to absorb energy at the end of the slide's travel rearward.
The P10, adopted by many German State Police forces, is in fact a USP Compact with the addition of a spurred hammer.
The KSC P10 is a high quality and reliable version of the USP compact; it offers a light double action trigger with a crisp blowback and operation with decent power. Unlike the Real Steel P10, the KSC replica does not have a spurred hammer. This version is installed with the System 7 blow-back chamber, and will require System 7 compatible magazines.
Metal parts include:
1x 24rd Magazine.
Adjustable Front and Rear Sight.
The safety is combined as a decocking lever - pulling it down all the way and the hammer uncocks automatically. Upgrading to metal slide and barrel (includes stiffer recoil spring) is highly recommended and gives this USP a very realistic and solid feel!
Please take note that only System 7 magazines will work with this P10.
