Hey Blaster, hope this is not too late but I have put over 100,000 rds through Citori's and I know what the problem is. The locking block is worn, pretty simple for a smith to fix and not a big expense. I have Jerrie White in Ft. Collins do mine, he is precise, quick and not that expensive. Broke my first 100 straight with a Citori in Laramie Wyo. Best gun for the buck going. Good luck.
