picked up my new 452fs the other day. nice gun, but the trigger left something to be desired. kinda of rough and heavy. so last nite i took it apart to see what could be done. getting the roughness out required a bit of honing, but the weight of pull is a snap. simple thing most anybody can do. on the rear of the trigger there is a post holding the trigger spring. just pop out the pin holding the trigger in place, and replace the spring with a lighter one. there is also a spring holding the sear but don't mess with that one. it keeps the sear engaged. just changing the spring i got a nice 2# pull

Congrats!Those are great guns.You might want to check out the CZ forum at Rimfire Central.

You can buy a kit on gb or ebay (yodave) that has 4 different springs and spacers that allow you to adjust pull and creep - I've got em in two now- Yeah , do not take the sear out -you don't need to- there a ball bearing and spring in there thats a bitch to get back in

I agree with mousegun1 the yodave kit is the way to go. put one in my 452 American and the trigger is super.

Where do you find a yodave kit?
