    "has a trigger variance pull of 2lb 7oz to 2lbs 9oz"

    That's the sort of thing that had so many people working on their triggers. I don't like them varying that much.

    From my years of active membership at RFC I thought every CZ rimfire owner worked on their triggers. The factory triggers I've tried were passable and certainly usable, but not clean, crisp and consistent. I bought a Brooks kit for my WMR American back when he first started selling them and it made a big difference. It was still not like a Cooper or Jewell trigger, but really nice.

    My 452 trigger was heavy with noticeable creep until I installed an Eric Brooks trigger kit on it. Now it breaks cleanly at 2 lbs with no creep. It's perfect.

    My factory trigger was clean and crisp! When I put in the .40 cent #143 spring, the trigger is still clean and crisp.
    What a difference 8oz makes! My scores will surely go up.

    I have a CZ452 varmint with thumbhole stock I purchased for half price. Apparently the thumbhole was unpopular in the area. I have obtained MOA at 100yards and about 2.5" at 200 yards. The trigger has a lot of creep in it, but I manage to do OK.

    I am about to put a Basix trigger kit in it. You need a 3/32 or 2.5mm pin punch, a good vice, a light plastic face hammer and a little patients. Oh yes, take the scope off! This kit has adjustment for weight and creep.

    I just reworked the trigger on my CZ455 which is similar I believe. Due to inflation a spring from Fastenal cost me $1.33. I made my own shim tube for sear engagement and now I have a safe 1lb trigger with no creep. I was able to achieve lighter pull in the single ounces but don't want that with this rifle.

    It's not a Jewell but then again it only cost me less than $2 and a little time.

    Wow. I've got a 453 Varminter with the single set trigger. Even in non-set, the trigger is great. With it set, it's outstanding. I have a match trigger in my AR, a Timney in my other AR, and my S-I-L has two Savages with Accu-Trigger. I'd put it up against any of them.

    I have 7 CZ 452s, all purchased new. Out of the box the triggers varied from good but a little heavy, to a bit creepy and heavy. The Ultra Lux was the worst due to excessive creep (but still good compared to many guns). I replaced the trigger spring on each gun with the ACE Hardware #144 spring (there's also a Fastenal spring that's known to be a good replacement) and all but the Ultra Lux now have great, relatively light triggers. Some of them required a few hundred rounds or so to get to their best, but they are good. The Ultra Lux is the only one that I think may require shimming to completely eliminate the creep, but I haven't gotten around to it yet.

    Yep. Put me in the camp with the others whose triggers are just fine. I bought the shim kit, but haven't felt the need for the install.

    Since the thread has been resurrected. :D

    I like my CZ452 Trainer trigger as it is, too. I only notice a tiny bit of draggy creep shooting off a rest. As a field rifle trigger, it is better than most triggers I've used out of the box.

    My CZ452 Ultra Lux came with a fine trigger, but was heavier than I wanted. So I put a trigger kit in it ($14 at the time) and now it is great, if you like flashlight triggers! :evil:

    Yo-Dave kit for me. Different people have different opinions of a "good" trigger. Most would think mine way too light for their taste.

    I make my own tube shims and cut 1-2 coils off the spring. I have done over a dozen rifles for happy campers.

    I own 6 CZ-452s and a -455. 3 of the -452s needed a YoDave kit. They will all shoot a little under .5" at 50 yrds except for my -452 Style. Can't seem to get it tuned in.

    All my CZs seem to shoot better after a few hundred rounds.YMMV.

    I really don't understand the reasoning behind the couple hundred rounds thing, but my two were the same. My .204 was incredibly bad until I shot maybe 150-200. Went from shooting patterns to sub .5's. Dunno.

    Just a single 452 Trainer, extreme creep but adjusted down nicely. I shimmed the sear and removed the nut, just a hint of creep now at about 2 lbs. but a hint mushy. Bought a half-dozen #144s JIC but they're still in the bag.

    For out of the box, I preferred my CZ's trigger to almost every other rifle trigger I've tried stock. Exceptions would be my Model 70 and a Rossi single-shot. I'd call the CZ "nice" compared to many last generation factory offerings but it loses out to newer models by a fair margin. Easy to tune (and cheap) if you're of the inclination.

    IMHO creep in any form is bad, very bad! The Yo-Dave will eliminate all creep for $20 and 15 minuets of your time.
