Apex Tactical 107003 Action Enhancement Trigger – Drop-In for S&W SD9/40/357, SDVE9/40/357, Sigma
If you’re running a Smith & Wesson SD or Sigma series pistol and you’re tired of that mushy, hinged factory trigger, this is the fix. The Apex Tactical 107003 Action Enhancement Trigger is a direct drop-in replacement that ditches the factory hinge for a solid-body polymer trigger with a center-mounted pivoting safety. No gunsmithing required. No guesswork. Just a cleaner, more predictable pull.
Here’s what you get: pre-travel reduced by roughly 20%, over-travel cut by about 10%. That means less wasted movement before the break and a more defined stop after it. The rounded trigger face gives you a smooth, consistent surface for your finger – no sharp edges, no pinch points. It’s built for repeatable accuracy, whether you’re at the range or relying on it for personal defense.
This trigger works as a standalone component, but if you’ve already installed an Apex SD or Sigma Spring Kit, it’s a perfect match. The combination tightens up the whole action and gives you a trigger that feels like it belongs on a better gun – because it does. Apex Tactical knows what they’re doing, and this part is no exception.
