 The third one, known as the CS/LW9, was developed by the China Ordnance Industry Research Institute in 2005 in an attempt to do a similar system to the Israeli-made Cornershot.It has a handle at the bottom that can be used to turn the LW9 to the left or right.The three systems use the QSZ-92 as the main pistol, although the LW9 also uses the NP22/34 pistols.
