    Any observations on the pros and cons, excluding cost, of the triggers available for the CZ455? In particular, the factory trigger with Yo Dave upgrade, the Timney trigger, and the CZ Fly Trigger. Do any other triggers exist?

    Probably no one trigger is best for all uses. My game is position shooting and my love is standing as the true test of marksmanship.

    Thanks, Rick

    I like the one that Rifle-Basix's offers. - I put them on 3 different 455's - No problem getting it down to 8-10 oz. without a lot of creep & travel.
    $99 bucks is what I paid for them.

    I installed Mr Fly in both my CZ455 rifles. Would highly recommend them. Yes, they are pricey but with it to me. I had tried the DIP springs and sear but just never got it working correctly.

    Before you start spending bigger bucks, try the YoDave kit. With a little experimentation, simply following the path laid out in the directions, I ended up with a very light trigger with no creep that passes all bump tests, all for the princely sum of about $23, including postage.

    The Mr fly trigger is to 455 as Kidd is to 10/22 in my opinion, very nice trigger. I have one in my 455.
    I didn't have a problem with the factory trigger, just wanted to fancy my 455 up. The yo Dave kit will probably serve you well.

    Hi Rick,

    Those are your main aftermarket options, as I understand it. I shoot a 455 in smallbore Hunter Silhouette, and I use the Yo Dave kit. I've also tried the Timney on another person's rifle - it's fine, and works just as good. In Hunter Silhouette, there's a minimum trigger pull (2lb), and Mr Fly can't go up that high without adding aftermarket springs. I'm sure it's a good trigger.

    In terms of work to install - Yo Dave seems like it would be the most work, because it's a "kit". I would argue it's the least amount of work. For the Timney trigger, you've got to install it to the action, PLUS route out some wood from the stock. Not a huge deal, but it's extra work. For Mr Fly, you've got to install it to the action, plus if you ever want to do Hunter Silhouette, you've got to mess with the springs. Not worth it, in my opinion. The Yo Dave kit is great if you are looking for a trigger pull around 1 or 2 pounds, which is probably what you want for position shooting.

    The only caveat I would mention, and I think this goes for all the triggers, is be careful if you have to drill out the front pin that holds the assembly to the action. Take your time, it's easy to go too deep and mess up the hangers - ask me how I know :) Good luck!

    I've got a timney on one of my 455s. I installed it no issue, and I think that it is set between 2# and 2.5#. I have a rifle basix on one that I bought from dj. The rifle basix is set right at 2# and works really well.

    I bought the DIP adjustable sear and springs first. I am an Industry certified armorer and armorer instructor for several handguns and for AR-15 but the little ball bearing in the CZ455 design just about whipped my heehaw.
    And I was never able to quite get the bolt stop[ to be 100% functional afterward.
    Next I tried the "drop-in" Timney. I never was able to get it down to the advertised pull weight. Also, my shooting buddy bought one for his and had the same issue. Yes, we both discussed with Timney and neither ever got below 4.5 pounds pull.
    The Mr. Fly is two-stage but comes with nice instructions on not only adjustment of pull weight but on how to dial out the first stage if desired. It did take some extra inletting in the trigger area to get it to fit but not a big deal.

    If money is no object look into a John Langley trigger.Go over to RFC to the Cz forum.They talk about them there.

    Did two 452's with the Ace spring. Best $.60 each I ever spent.
    Hint- If you launch the detent ball and cannot find it, Ace has balls, a tad larger that work just as well. If yu can work through a plastic bag with all parts inside the bag, even better.

    I tried the YoDave kit first on my 455 VPT rifle. With the lightest spring in the kit, I was able to get the pull weight from 3 lb 2 oz down to 1 lb 5 oz, which safely passed the "bump" test. For my purposes, that pull weight was sufficient. I wasn't looking to achieve a 2 oz BR pull weight, which seems rather futile in light of the inherent precision of the rifle. In my case, the shims were not necessary as the factory trigger had almost no creep to begin with. The only part of the exercise that might be considered even remotely challenging is removing the pins; mine were not too difficult, but that can vary from rifle to rifle. Obviously, if your trigger has a lot of creep, you'll have the additional task of installing and testing the shims, but again, that shouldn't be too difficult.

    Anyone considering a trigger replacement for the CZ 455 should check out the CZ forum at Rimfire Central where there are some reviews of the various options. Like most replacement options, there are a range of opinions regarding replacement triggers that might be useful in making a decision.

    It is like everything else. You are not going to make a lower tier rifle shoot like a good CZ and you are not going to make a CZ shoot like an Anschutz 54 action, round, rectangle, triangle or otherwise.

    I'm fortunate that my new CZ455 came with a good trigger. It had zero creep and about a 3 # pull. I replaced the factory spring with the lightest spring from the Yodave trigger kit. It now has less than a 1 # pull that breaks like glass. I can close the bolt fast and hard safely. BEWARE, with a trigger spring this light it will not pass a bump test when the stock is bumped hard on a surface with the rifle in a vertical position. The inertia of the trigger overcomes the light spring when bumped vertically. In my opinion a trigger this light is only good for a rifle that is pointed downrange anytime the bolt is in it.

    Yes the John Langley trigger does have good reviews and he will adjust trigger pull weight down to a few ounces if that is what you are looking for. I have an adjustable sear and spring kit from Dip inc. Works very well. If you are planning on adjusting below about 9 oz. on your trigger be advised the spring also works with bolt retention so the bolt may fall out when cycling. The Langley trigger doesn’t have this problem from what I read.
