have had issues with a Mark IV with screws loosening from firing? I watched a You Tube video where some guy was trashing the pistols due to sights and other thing coming loose. He said he didn't want to use blue loc-tite on his gun. It took me a few minutes to loc-tite all screws on mine. No big deal.
