    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 .
