Just a slight photo update to replace the rather basic one I took previous.
Its a replica Heckler & Koch (HK) USP Tactical produced by Tanio koba.
Shot with a canon 500d.
The USP Tactical (9mm Parabellum, .40 S&W, .45 ACP) incorporates a fully adjustable rear sight, a higher-profile front sight (as to be visible above the suppressor), an extended threaded barrel and O-ring, a match grade trigger, and an adjustable trigger stop. Sound suppressors designed for the USP Tactical are available from Knight's Armament and Brügger & Thomet.
A unique feature of the USP Tactical is that the barrel is left-hand threaded (counter-clockwise to tighten), which makes the pistol incompatible with suppressors designed for the MK23 Mod 0.
The KSK of the German Army and the German Navy Kampfschwimmer use the USP Tactical under the designation "P12".
