The Timney replacement trigger for the SIG MPX is the latest in the Timney lineage of AR-style, semi-automatic, replacement triggers. Timney is offering two models for the MPX curved and straight shoe options.
The trigger, hammer, and bridge are constructed of heat-treated steel. The housing is machined 6061, T6 anodized alloy and the trigger is factory calibrated for a pull weight of four pounds with a two-pound first stage and two-pound second stage for the two-stage model.
The trigger 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.
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.
