HNP45acp,
I have no experience with the SA only versions so I cannot comment there, but as far as the SA/DA versions go the SA can be quite good. A lot of times people will do a home trigger job, or just dry fire them a few thousand times (with a good snap cap, not the ones that come with the new CZ's). The CZ-85 COMBAT and SP-01 SHADOW do not have a firing pin block so will likely have a better SA trigger than those with the FPB. A 15lb. (or slightly less) mainspring will help things a bunch too. Some people will also install a softer trigger return spring, or bend the factory one to have less tension. As far as the reset, fairly long in the SA/DA models, nothing like a 1911, and quite a bit longer than a Glock (or any striker fired gun I suppose). It's not terrible or anything, but it's there. The advantage is it's a true double action if you need to strike a primer again.
Out of the box you just can't tell, some have good triggers, some need some work. They will all have some camming of the hammer (for safety reasons), but it's easy to remove 90-95% of it with a home trigger job.
