Amazing Trigger

This trigger is amazing and is specially designed for the SIG MPX with a trigger bridge. Christine in CS was a fantastic help. She was very knowledgeable and was able to explain to me two different triggers for the MPX and educated instead of pressured. Thank you!!

Great upgrade!

Love the MPX platform but not a big fan of the stock trigger. The Timney trigger was easy to install and after a few hundred rounds I can say that I love the upgrade, it has a smooth constant pull, it breaks crisp, and it has made shooting my MPX a lot more fun!

What Is Trigger Pull weight?

Pull weight is the amount of pressure, 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.
