CZ455 22 lr Trigger

Most CZ 455/457 shooters I know, myself included, just get the YoDave spring and shim kit. Very cost-effective and easy to install.

Yes I have one CZ455 now and just Sold a CZ455 with the Yo Dave spring kit's - They do work Well ! This rifle i just bought came with the CZ Fly Weight - just thought i would see how popular they are RJ
 
I've got one, and while it can go light, it's not that great of a trigger. Feel is mushy rather than crisp. In the USA, a fellow by the handle of BSCAR and I think John Langley as well, make about the best triggers you can get for a 455. Would have to jump through some import hoops to get one, though.
 
Hy Jim , I installed a Flyweight in a 455 Evolution , really liked it .

Ended up selling all my 455's (3) after buying a 457 MTR , the 457 trigger
is xlnt .. I now have .22 & .17 HMR.
The 457 MTR is twice the gun that the 455's were/are.

They're that heavy? ;)

Seriously, twice as good might be an overstatement. Here's why.

If the height of the bolt lift matters a great deal to a CZ user, then the 457 has the advantage of having one that is less than the 452/455. If the safety of the pre-457 CZ bolt rimfires is an issue with a CZ user, then the 457 has the advantage of having a safety that is forward-back lever on the side of the receiver rather than the safely lever on the back of the 452/455 bolt. The triggers are a big difference between the 452/455 models and the 457's, but neither one can be safely made to be lighter than the other (both need spring changes), although the 457 trigger adjustments for sear engagement and overtravel built in, which is an advantage over the earlier models. The trigger guard and bottom metal on the 457 is an improvement over the 452/455, but not one that changes how it performs. In fact, none of the design changes affects how the models compare when it comes to how they shoot.

The foundation of a rifle's accuracy is the barrel, and these are essentially the same on the 455 and 457. To be sure there are two models in .22LR that have the match chamber, the MTR and LRP, but the rest of the barrel is otherwise no differently made than those of other 457's and 455's, even if newer models have barrels of different lengths. CZ barrels can be good or they can be bad, but most are somewhere in between. Barrel quality differences will always be what distinguishes a CZ that is a good shooter and one that is average or, worse, a poor shooter -- regardless whether its a new model or a previous one. In short, there's nothing to suggest that despite design changes in the 457, that the new model is a better shooter than the 455, the potential confered by the match chamber on two 457 .22LR models, the MTR and LPR, aside. In any case, if the barrel is middling at best, a match chamber will not make it shoot like a match rifle.

Among the previous models there was debate as to whether the 455 was equal to the 452. No opinion is offered here as it will take too much space. The 457 has some design changes that many shooters will applaud -- the lower bolt lift, the side lever safety, the trigger, even the bottom metal. But the most important question about the CZ models is "how does it shoot"? This is where 457 models (except perhaps for the MTR and LPR) and 455 models are on equal footing.

And this /\ says it all. I’m sticking with my 452s.
 
Whats the diff's between a CZ452 and a CZ455 then ?? Thxs RJ

The 452 models have threaded barrels, except the 17HM2, which are pinned. The 455 modesl have barrels that are attached to the receiver with two grub screws. The barrels are interchangeable between models (barrel channel permitting) and it's possible to change calibers, from one rimfire to another -- .22LR, 17HMR, and .22WMR. Only a new magazine and possibly a magazine spacer is needed when going to .22LR from a magnum. The 455's all have 11mm dovetails and two action screws, both located the same on the various 455 models. Among the 452 models, some have two action screws, some one with a barrel lug. A few models of 452's have 3/8" dovetails, the others 11mm. The triggers in both models are very similar but not exactly the same.
 
I guess I am a way out of the “loop”. I have 9 455’s and one 452. I have never changed a trigger nor fiddled with them. I have big **** hooks, and pulling a trigger on a dinky rifle is not a worrisome problem. To be fair, I don’t use the rifles for target shooting, just gophers and plinking.

I'm DEFINITELY no authority on these matters, but, using a rifle with a good trigger is a bit like picking up a high-end fishing rod for the first time. If you're experienced enough to be able to tell the difference, you'll immediately want one in your life. If you can't INSTANTLY tell how much of a difference it makes, you may never see the merit in upgrading.

To be clear, I'm not saying one is good/one is bad-I think some people want to just keep exploring/learning, other people are content with how things are running, get used to it (good or bad), and move on. For me, the trigger is probably what I'm most concerned with, provided I'm confident that everything else is working the way it should. :) At this point, my goal is to get all of my rifles around the same in the interest of consistency. If I add a rifle to the quiver with a 5lb. trigger, and all the others are under -2, I'm confident I won't shoot it as well out of the gate. I should add, I don't (and won't) own a rifle with a trigger pull weight measuring in ounces. (only) I'm usually chasing a pull weight of 1-2lbs.

As for the CZ Flyweight trigger-I've seen them for sale and honestly, I'd have probably tried one if they were available for the 452. Instead, mine have Yo Dave kits installed. Not sure if it's something about the guns, but one of my 452s is nice and light, the other less so. Both have the same kit. I have put Rifle Basix triggers in 2 Marlins, and they're spectacular. I've contemplated a RB trigger for the CZ 452 several times.
