When purchasing Apex Tactical Specialties or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

Apex Tactical’s Aluminum Action Enhancement Trigger Kit is engineered to give the S&W M&P 9mm/.40 a smoother, more consistent, lighter (5 to 5-1/2 lb.) trigger pull with a shorter reset than the factory trigger.

The Apex M&P  9mm/.40 Aluminum Action Enhancement Trigger Kit also lessens pre- and over-travel by as much 20%, while the rounded machined aluminum trigger shoe provides a comfortable, secure contact point for the trigger finger.


Center mounted pivoting safety maintains factory safety values

Keeps safe trigger pull weight for duty/carry applications

Contains: trigger, heavy-duty sear spring, machined sear, duty/carry spring set, Ultimate Striker Block Kit & slave pin for installing trigger return spring

Fits all S&W M&P pistols in 9mm and .40 S&W

Does not fit M&P45, M&P M2.0, M&P Shield, or .22 LR models


Although the Apex Aluminum Action Enhancement Trigger Kit for M&P 9mm/.40 is designed to drop in and normally should not require further gunsmithing, armorer or gunsmith installation is recommended.
