Picked this up yesterday, and by far the tightest CZ I own! The slide to frame fit is like a top end 1911. The DA trigger is terrible, but the SA isn't to bad. I swapped in a 17# mainspring, and it helped a bunch. The SA now breaks at 4.5#, and should lighten up after some shooting. I was kinda hoping it would fit in my G23 holster, but the slide catch is in the way, and it bows out. Don't wanna ruin the retension for my Glock. Hope this shoots as well as my other two CZs, we'll find out this weekend
