Just bought a blue steel target version. Shot at a indoor range this past week. Off hand with bulk Federal and CCI MiniMag. Both shot very good. Need to shoot it out doors at some distance off a bench and try Auto Match. Had a Mark 3 before and never took it apart and eventualy sold it off. This Mark 4 is a joy to take down. I believe I wiil have this one for as long as I will be able to pull the trigger. By the way the trigger was ok out of the box and was better after the range session. Will see if I have to do anything to it down the road.
