    Had a Timney in a CZ myself, changed back to a Yodave kit, blade is too narrow on the Timney and can't lower it as much as with a Yodave.

    Does the yodave kit affect the safety of the rifle, i hear that they can be safety concerns when dropped? Is it just a spring change or do you need to file down the sear

    Get yourself the CZ Flyweight Trigger, you can buy it direct from them

    Had one in my 455 before I changed to the 457. Super trigger

    You get springs and shims in the kit.
    The springs lighten pull of the trigger.
    The shims adjust the amount of creep by reducing the distance before engaging the sear.

    It's the shims that you need to be careful of, as if you use one that, not only removes the creep, but also puts pressure on the sear, then it already moves towards releasing when you close the bolt.

    To change the shim, you will need to drill or file off a pin.

    You don't have to change both the shim and the spring, you can just change the spring (pretty easily) by yourself.

    Not sure if my terminology is 100%, but if I will say, for the price of a yo-dave kit and how easy it is to change the spring, it might be worth trying and see if its good enough for you.
    I know a good few people who really liked it, including myself when I had the 455.

    I have a Timney trigger on my CZ 452 .17hmr....it's brilliant, I can take my hunting rifle onto the range and shoot alongside the best of the benchrest guys...you will love it...but they are pricey, thats what puts lads off putting them in rimfire rifles.
    Mine came from the States .
    A guy in the UK has them for sale.

    Just to add a spring only swap out can cause safety issues. When fitting the kit to a 452 Lux I started with the lightest spring and the rifle would go off with a vigorous bolt manipulation! Also a bump test needs to be done, a tap pf a rubber mallet to the butt or drop the rifle onto the butt from about 12 inches onto a rubber mat to see if it's safe.

    I done two 452's with just springs, a HMR that has an unbelievably crisp trigger and a .22LR which has the slightest bit of creep.

    First they came for the socialists...

    I have had the YoDave kit. Timney Trigger, (fitted in my 452 16" Amarican) and the adjustable sear trigger from "DipInk" in the US (now fitted in my CZ 455 16" varmint rifle).

    YoDave kit is good and very good value for what you get and can do to your CZ triggers.

    The Timney was very good, and I think better than the YoDave. With the small hex screw you can adjust the sear engagement.

    The 'DipInk' adjustble sear is also very good. Again a small hex screw adjusts the sear engagement. Just as good as the Timney Trigger IMO.
    If you go for the DipInk, find the product code on the website. Then go to
    https://www.kinneysshootingsupply.com/category-s/191.htm
    to order, the postage is cheaper.
