The stock Sig MPX trigger leaves a little bit to be desired. If there is one thing you should upgrade, it is the trigger. Luckily, Timney now offers a single stage trigger designed for the MPX platform with all the same features you love from their AR-15 line of triggers. It utilizes a simple drop in design with aluminum housing. It fits snugly in the trigger pocket with no interference of the trigger “bar” and is designed to withstand the forces of the MPX action. Like all their other triggers the break and reset are extremely crisp and short. It is factory tuned to break at 4.5 lbs., so it is not too light but not too heavy making it great in a home defense set up or truck gun. The internals are wire-EDM machined for extremely precise dimensions and the hammer is made from S7 tool steel for long lasting performance. The Timney Sig MPX Trigger is a great way to upgrade your gun.

Timney Triggers was founded in 1946 with the mission to bring consumers high quality, precision AR-15 and AR-10 components. They have since built a reputation that resembles this sentiment by providing triggers that are optimized for competition use by competition shooters. If you have an AR, it needs a Timney trigger.
