I bought a six inch GP100 and found it to be shooting high, even with the rear sight crank almost all the way down (about 4 to 6 inches high at 50 feet), so I notified Ruger of my problem and sent it back. They returned it to me with a picture of a target with six shots grouped almost dead center if not slightly low, marked '158 grain American Eagle at 15 yards'. Also inside the case was a nice, new Ruger lens cleaner (presumably to clean my glasses with). There was no note or explanation or anything (other than the type of ammo and distance), just the picture of a target and a lens cleaner. Very funny.
