    Cz457 mtr

    I have recently bought myself a new CZ457 with Walnut stock. A very nice rifle with good accuracy. There is a problem. The trigger weight from the factory is 4lbs. This is too high for a target rifle. A spring kit is available from the USA and I bought one and fitted it. This reduced the trigger pull to 1.8lbs which I think is still too heavy for a target rifle. The next step is to fit a Timney trigger for £200. This will allow the trigger to be adjusted down to 10 ounces, which is a little light, I would prefer about 1lb. Why does an excellent target rifle have such a poor trigger?

    I recently bought a synthetic 457 and the trigger spring was heavy so i replaced it with a Biro spring and now it is just under a lb.
    Sweet as a nut. I use mine for rabbiting.

    I thought the 457 trigger was fully adjustable, unlike the old 452.

    I tried adjusting mine as seen on youtube but it made no difference. So a lighter spring was the answer.

    There are a few suggestions online on how to tune up the triggers such as the following .

    Iíve done this on a dozen or more czís down the club. It makes a huge difference. Easy to do and equally easy to undo.

    I think the manufacturers put a huge trigger pull on as standard so that you canít sue them if you have an accidental discharge.

    I adjusted the trigger down as far as i could on my 457 varmint, just to the point it wouldnt engage and backed it off slightly and it still too heavy. I too am considering a Yo Dave spring kit as i have a pal in the states that could post it to me. But as for £200 on a Timney.. hmmm Iím already parting with £600 for a stock for it another 200 bills on a trigger and all that bleating about how Iíll never pay a grand for an air rifle again after how little my rim fires cost will be out the window.
