The Timney Sig MPX Trigger is constructed of heat-treated steel and the housing is machined from 6061 T6, anodized alloy. The trigger is single stage with a straight blade and built with heat-treated, coated with black oxide. The Sig MPX is self-contained, drop-in trigger ready that does not require gunsmithing, fitting or adjustments. A hardened steel bridge is designed to protect the trigger components and set screws are located in the housing to lock the trigger in place and prevents the pins from moving out of place.
