The TriggerTech ARPTBB36NNF Adaptable Two-Stage Flat Trigger for Sig MPX is engineered to deliver a crisp, predictable break with an adjustable pull weight from 3.5 to 6.0 pounds. Built around TriggerTech’s Zero Creep and Frictionless Release technologies, this drop-in unit uses a robust 7075 aluminum housing and hardened 440C stainless steel internals, finished in clean black PVD for durability and corrosion resistance.

Designed specifically for the Sig MPX platform, this straight lever trigger offers a short two-stage feel with minimal overtravel and a fast, sub-0.015" reset, making it well suited for competition, precision range work, and demanding training environments. The external CLKR adjustment screw lets shooters fine-tune pull weight in 2 oz increments without removing the trigger, reflecting TriggerTech’s focus on practical innovation and refined craftsmanship.
