    Summary: I can't fully compress my finger pad before the striker releases. With the #2 spring in, if I smack the ground hard, the gun will go off. I'm too lazy to actually go through the whole mod and put another, heavier spring in, and I kind of like my under-two-pound trigger pull. Besides, the safety on the 452 actually locks the striker, so I'll just use it for now.

    Go here. You want both the kit and the removal fixtures.

    My 452 FS:

    Everything laid out:

    The kit contents, from left to right: springs on top of anti-creep tubes, bag the fixtures came in, pin insertion fixture, pin removal fixture.

    Springs:
    [​IMG]#1 through #4, which are (estimated pulls) 0.75~1.00 pounds, 1.00~1.25, 1.50~1.75, and 2.00~2.50. For reference, the factory spring is 3.50~3.75. I used the #2 spring.

    Action in the removal fixture:

    Mr. Brooks' handy "DO THIS" picture for removing the trigger:

    After that, all you do for the spring is slide off the old one (if it doesn't just fall off as you pull the trigger off), and slide the new one on. Note that the muzzle is now pointing to the LEFT, as you will have figured out from eyeballing the removal fixture.

    Note that I was not able to completely remove the front trigger pin—this doesn't matter, just push it out far enough for you to get the trigger clear of the sear.

    Mr. Brooks' handy "DO THIS" picture for inserting the anti-creep tube:
    [​IMG]
    Note that the muzzle is now pointing to the RIGHT.

    From here, you just slide the trigger over the sear (working the spring guide rod into the waiting hole in the action), set the whole mess down on the pin insertion fixture, and tap the trigger pins back in.

    Done. It took me about ten minutes, including time to take pictures and hunt down the rear pin after I realized it was on the floor.

    My 452 now has ZERO creep, and suffers from Telepathic Trigger Syndrome.

    SN, will this work on a CZ 452 Scout as well? TIA.

    Excellent thread Stiletto Null! Thanks!! :)

    Eric is the man when it comes to CZs......

    BTW: I love the full length Mannlicher-style walnut stock on your FS.

    You can also use the built in adjuster to go up in trigger pull weight. It is the nut below the spring.
    Be careful in going too lite, if the gun will go off after hitting the butt fairly hard it could go off when taking the safety from safe to fire.

    For what you pay for the Brooks kit, it is a pretty good deal. It is, however, somewhat limited as the adjustments are discrete and not continuous. That is, you may not get the best combination of parts for the best trigger feel as opposed to a fully screw/nut adjustable trigger system. But, for the price, a very good deal for a much better than the stock trigger for the CZ.

    I gotta say, IMO, this is pretty dangerous.



    I've had pretty good luck with the early Timney and the Automation Solution systems. A bit more pricey but more adjustable. Also, I don't like paying through PayPal.

    I am using Eric Brooks' trigger kits and Weaver base adapters on both my CZ 452 trainer 22lr and my CZ 452 American 17hmr. Excellent products..........

    But it requires a pretty hard jolt (like a buttstroke). Normal jostling won't set it off, nor will simply disengaging the safety.

    I'll try a narrower anti-creep tube in a bit, but I'm not worried about the gun just going off because it feels like it.
