I've been doing 'Bill Drills' with my (new to me) CS-9; trying to draw and place 5 rounds on IDPA -0 circle ( I think 8"dia.) at 7 yards in under 2 seconds. I'm using the front sight 'combat-style' but I really don't have time to accurately line up the rear. I'm no expert by any means, but I guess it's a matter of what you're trying to accomplish with a defensive pistol. Speed and accuracy are a balancing act until you find that groove.
