Product Info for Timney Triggers SIG MPX Straight Trigger

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.image

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.
