What Is Trigger Pull weight?

Pull weight is the amount of force, in ounces or pounds, required to fire the trigger. Or in other words, how hard you have to squeeze the trigger to shoot your rifle. Timney Trigger experts at our Phoenix, Arizona plant hand-test every trigger in its intended action and then set the pull weight at our factory standard, 3 lbs.

If you prefer a different pull weight you simply select it from the drop down above and your Timney Trigger will be customized to your preference.
The #1 reason to replace your factory trigger with a Timney is accuracy. A lighter, crisper, more consistent trigger pull will make you more accurate with your firearm.

Below is a guide for pull weight selection:

2-2.5 pounds
Light trigger pull weights are great for people shooting lighter weight rifles as they can help keep you on target during the shot. Also common weights for target shooting from a bench.

3-3.5 pounds
By far the most common trigger pull weights -this is great for virtually all applications including target shooting, hunting and 3-gun competitions.

4.0 pounds+
Heavy trigger pull weights are good for cold weather hunting or applications where you may be shooting with gloves on.

    Great trigger - at least that is what I am told

    I wish I could be the one that has actually pulled the trigger - but I can't get the gun away from my husband to try it. He has stuck me with the Winchester model 75.... with its old, nasty trigger and is hogging the CZ with the Timney - sigh! But from what he has told me and looking at his targets the trigger is smooth has a great pull and adjusted to exactly where he wanted. He put it on his new CZ Grand Finale and loves it. He says it is smooth, has a nice break point on it - is exactly what he wanted. Don't fret - there is hope. When he gets his new Rock River built I might end up with the CZ Grand Finale. If not - well then I might just have to buy my own CZ and put a Timney on it. That will teach him for not sharing LOL! Seriously it is an excellent trigger - good enough I haven't quit whining about getting one for me.
