I bought mine used. The previous owner replaced the hammer/trigger, etc.
No idea what work was done or who did it. Trigger pull is about 1&3/4 lbs. One of those pistols I'm careful with when I take it to the range - careful to dry fire a few times first so my finger/brain realized there is not take up similar to my other CZ's. If I don't dry fire first I usually end up with a round dropped about 4 to 6" low out of the group that goes while I think I'm taking up some slack.
On the CZ's with a firing pin block I can feel that firing pin block move up/stop just before the trigger bar starts to move the sear and I stop at that point (where the firing pin block it up/out of the way and the sear hasn't started moving yet.) But on the TS, any rearward movement past that tiny little stop results in a bang as there is no firing pin block and the trigger/sear engagement is set up the way it is.
Oh, picture of the hammer on my TS. The thing is a tad tight when the picture was taken. If the slide was eased forward it would stop just before lock up. No issue when the slide moved forward at speed from normal shooting or when using the slide release to chamber a round.
