The Timney replacement trigger for the Sig Sauer MPX is the latest in the Timney lineage of semi-automatic, replacement triggers.  Timney collaborated directly with SIG on the design and features of the MPX drop in replacement trigger. 

The trigger, hammer, and bridge are constructed of heat-treated steel.  The housing is machined from 6061 T6 anodized alloy and the trigger is heat treated steel and coated with black oxide .

The trigger is single stage and features a straight blade. The Timney replacement trigger for the SIG MPX is a self-contained, 100% drop-in trigger ready to install in your rifle for an exceptionally smooth, crisp, trigger pull with no gunsmithing, fitting, or adjusting required.

The MPX replacement from Timney features a hardened steel bridge to protect the trigger components from the vigorous bolt blow back characteristics prominent in Pistol Caliber Carbines.

The single stage trigger features a non adjustable trigger pull weight of 4.5 pounds. Drop in installation is simple once the Factory trigger is removed, you will reuse the factory Hammer and Trigger pins.

Set screws are located in the housing to lock the trigger in place and prevent the pins from walking out of place.

The Timney drop in MPX trigger works with the factory safety as well as many aftermarket replacements, especially the Timney 49r ambidextrous, short throw safety available here on the website.

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.

This trigger works with these rifles:
