No tools required for the Mark IV Disassembly / Assembly procedure.Yeah it's a great gun at a great price!
The target model has the blacked out target sights which I really like and it also has the heavy bull barrel. When taking it apart you just need to remove the Allen screw under the barrel and the bolt slides out of the receiver for easy cleaning. I can shoot quarter sized groups at 30ft feet all day with this pistol that has almost no recoil because of the heavy barrel.
