 The guns that Vincent carries are a Heckler and Koch (HK) USP .45ACP  and a Ruger Mk II .22 with integrated suppressor. Vincent didnt use  a silenced USP Tactical or Mk.23 SOCOM as was previously suggested.  The silenced pistol was a .22 Long Rifle caliber Ruger Mk II with  the upper receiver and barrel replaced with a custom integral  silencer.
