NickB65 Posted April 25, 2014 Report Share Posted April 25, 2014 Has anyone tweaked the CZ 452 .22LR trigger to make it a little lighter and if so which kit did they use? Love the rifle but it is a little stiff and a little lighter will make it so much better. Thanks Quote Link to comment Share on other sites More sharing options...
Redgum Posted April 25, 2014 Report Share Posted April 25, 2014 I got one from Rimfire magic but it was quite a few years ago, its not difficult but a little scary if you have never done any gun work. It makes a lot of difference to a CZ 452 trigger but just make sure you do the safety checks after you have fitted kit. Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted April 25, 2014 Report Share Posted April 25, 2014 I bought a Yodave from America, via the internet. I only changed one spring and it made a vast improvement. Rimfire Magic do teh same type of kit, and around the same price. Quote Link to comment Share on other sites More sharing options...
fruity Posted April 25, 2014 Report Share Posted April 25, 2014 The triggers do let them down a bit., put a rimfire magic kit on my 452. made a big difference, nice light crisp pull now Quote Link to comment Share on other sites More sharing options...
rtaylor Posted April 25, 2014 Report Share Posted April 25, 2014 I used a yodave kit. Worked a treat. Rimfire magic is probably quicker. Nether are expensive. Quote Link to comment Share on other sites More sharing options...
saddler Posted April 25, 2014 Report Share Posted April 25, 2014 Mine was fitted with an Eric Brooks kit Used one of the three sets - still have two of them sitting unused here Quote Link to comment Share on other sites More sharing options...

welshwarrior Posted April 26, 2014 Report Share Posted April 26, 2014 Rimfire magic Yo Dave are all basically identical. I've used both all work fine. Quote Link to comment Share on other sites More sharing options...

Rimfire Magic do teh same type of kit, and around the same price. Same here Steve, just changed the spring from the kit, to the lightest one and its perfect :good:Did both the .22 and the hmr for an identical pull Edited April 26, 2014 by turbo33 Quote Link to comment Share on other sites More sharing options...
moorvale55 Posted April 26, 2014 Report Share Posted April 26, 2014 If you do any alteration with any of the trigger kits available make sure you do a bump test. Close the bolt and take the safety from safe to fire then bump the butt of the rifle on the floor, if it fires the trigger is too light and not safe and you will need to fit the heavier roller. ATB.

Dekers Posted April 28, 2014 Report Share Posted April 28, 2014 All the kits are very similar and do a very similar job, and overall, in gun terms, none are expensive. If your trigger needs attention (they don't all), it is probably the best few £ you will ever spend on a gun! Quote Link to comment Share on other sites More sharing options...
kent Posted April 28, 2014 Report Share Posted April 28, 2014 Well I have two mates who both bought 455 varmints at the same time. man A (worst trigger ever pulled very heavy then ok) he shot it a lot never altered it to see if it ran in, it did took maybe 1000 rounds, I have used it its now just fine! Man B not so bad a trigger just felt like a new CZ always does, he altered his gave it a gunsmith who also fiddled he still was complaining last time the subject came up and has shot it a fair old bit also. Draw your own conclusions Me? I have owned two 452s both were fine once run in, the HMR I sold after 18mnths or so, the .22 I have had years and its a sweet as they get (heaven knows how many rounds it has fired but it likely into 10k plus. Also I have a 527 bought new about three years ago done close on 1000 rounds, never even adjusted it It concerns me that so much fiddling with triggers is done by those that do not always fully understand them enough (let the things run in before you even contemplate changes) What the trigger pulls at when you finish fiddling might not relate to its pull weight after 500 rounds and pull weight and safety are linked, the last thing you want is a nasty surprise on day flipping a safety off or closing the bolt. IMO a hunting rifle should not pull less than about 2 1/4 lb and is better about 2 3/4 - 3 lb ( perhaps even more if your wearing gloves)If you cannot shoot acceptably with a 2 1/2 lb pull then you need to work on your pull not the trigger. Its not bench rest shooting at the end of the day. BTW man A had a pull that at its heaviest I honestly had to re-check the safe catch as I couldn't get it to go off, then I told him " I think your trigger has just jammed" Quote Link to comment Share on other sites More sharing options...

For me it is a touch stiff and would benefit from a slightly lighter pull. I am not one to "tinker" as I have way too much respect for the kit and I am not a gunsmith but from what I have seen and read it is a relatively simple procedure....... I will let you know how it goes. Quote Link to comment Share on other sites More sharing options...
rabbiter Posted April 29, 2014 Report Share Posted April 29, 2014 anyone else that may read this and need some springs,i have 2 kits with 1 spring taken from each and the originals put back into the packets,one for a 452 and one for a 455,pm me and ill sort them out for you............DAZ Quote Link to comment Share on other sites More sharing options...
NickB65 Posted May 1, 2014 Author Report Share Posted May 1, 2014 Nick, I still have 2 spacers and springs left from my kit, if you PM me your address, I will stick them in the post to you. A HUGE thank you to BLUNDERBUST for sending me his spare springs - fitted one last night and oh man is it so much sweater. I could not fit the lightest one as that was so light the slightest bump and the trigger would fire - so i fitted the slightly stiffer spring which was about half the strength of my current one and now I only have to squeeze gently and it fires. Bumped tested by dropping it from four feet onto a pile of painting rags and it was fine. re-check the zero on Friday and then a Friday evenings shooting we shall go. Happy to send the spare trigger spring on to anyone who wants it but be warned it was so light in my gun that a slap on the side of the stock set it off.

I will let you know how it goes. Triggers are easy to do and easy to make unsafe. What does it actually pull at? Is it pulling a consistent weight of break? The issue is not is it safe enough when it leaves the bench its what it like after another 2000 or more. Pet bug bear of mine if you don't know how its all works give it to someone who does as its not a big expensive job in the best of hands, yes you do see bad and unsafe trigger jobs buying a used CZ I should check very carefully that all was good before using in the field for sure Quote Link to comment Share on other sites More sharing options...

Although, it doesn't point out or show you how to "bump test" your gun after altering the trigger. I'll let more experienced people explain this....
