I posted my original message after I had just returned from the range. But when I field stripped the pistol for cleaning, I FOUND TO MY HORROR THAT THERE WAS A BULLET STUCK IN THE BORE!. . . I swore to myself that I would be more careful and never let it happen again. Obviously I slipped up somewhere along the line.
Sid, I'd say you owe that CZ-75 a certain debt of gratitude.
Hope that when you've got it cleaned out it keeps on ticking properly.
