I have a Buck Mark 22LR which I feed approximately 400 rounds per week in two sessions. Two problems: first, the front sight mount screw looses 3/4 turn per 50 rounds, irritating but solvable. The other problem is more interesting. The slide will fail to lock back about 60% of the time after the mag runs dry. Symptom is the same with a new mag or a well worn mag. I clean the gun to the field strip level after 1200-1500 rounds.
What am I missing? Do I need a detailed cleaning? Is the loose sight plate related? The rate of lock back is no different with the sight plate screw tight or loose.
