The Apex Tactical Action Enhancement trigger is a drop-in polymer upgrade designed for Smith & Wesson SD and Sigma series pistols. It replaces the factory hinged trigger with a solid-body polymer trigger that includes a center-mounted pivoting safety and a rounded face for improved finger contact. When paired with an Apex SD or Sigma Spring Kit the trigger reduces pre-travel by approximately 20% and over-travel by approximately 10%; it is also effective as a standalone component. The design provides a crisper, more consistent trigger feel suited to everyday carry and range use.
