Manufactured by B&T USA, the SD-988178-US (formerly SD-987900-US) is a 45 ACP caliber suppressor which threads directly to the iconic Heckler & Koch MARK23 / MK 23 handgun.
In the US, the MARK23 was issued with the KAC / Knights Armament Company sound suppressor, but in Europe and the rest of the world, the silencer that shipped with MARK 23 contract deployment kits was this one; the B&T MK23 SOCOM .45 ACP pistol suppressor.
