THE USP9SD

The Heckler & Koch USP9SD is a full size USP9 variant 1 (SA/DA) 9mm x 19 NATO pistol fitted with a frame mounted left side control lever that acts as a combined manual safey and decocking lever. The standard USP9SD is fitted with match trigger partsand click adjustable sights of sufficient height to see over the mounted optional sound suppressor.

An ambidextrous safety lever and optional 3 dot tritium sights are also available. The barrel is threaded left hand, does not have an o-ring and does not require a thread cap.

An optional Brügger & Thomet (B&T) "Impuls IIA" stainless steel screw on sound suppressor is matched to the pistol via the last three digits of the weapon's serial number when they are assembled together at the factory.

The B&T sound suppressor was developed specifically for use on the HK USP9 pistol and has its own separate serial number. It is possible to reduce the sound signature by an additional 1 to 3 dBs over that of the dry suppressor by adding 5 cc of water to the sound suppressor baffles. It will also help reduce the first round "pop" often experienced with a dry sound suppressor. This water will help cool the hot propellant gases and will last for approximately 20 shots or 12-14 hours, whichever comes first.
