Apex Tactical 107003 Action Enhancement Black Drop-In Fits S&W SD9/40/357, SDVE9/40/357, Sigma

Description

If you’re running an S&W SD, SDVE, or Sigma and you’ve been fighting that factory hinged trigger, here’s the fix. This is the Apex Tactical 107003 Action Enhancement Drop-In Trigger. Solid polymer body, center-mounted pivoting safety, and a rounded face that sits flat and comfortable under your finger. No more of that hinged slop. Tactical Arms Depot ships these nationwide to all 50 states, so whether you’re in the piney woods of East Texas, the high desert of Nevada, or the suburbs of Ohio, we can get this to your FFL quick.

Apex Tactical builds this one to drop right into your S&W SD9, SD40, SD357, SDVE9, SDVE40, SDVE357, or any Sigma variant. You’re looking at about a 20% reduction in pre-travel and a 10% reduction in over-travel compared to the factory trigger. That’s not just a number on a box—that’s less wasted motion, a cleaner break, and a faster reset. If you’ve already got an Apex SD or Sigma spring kit in the gun, this trigger is a perfect match. It’ll also work just fine as a standalone upgrade if you’re not ready to swap springs yet.

Installation is straightforward. It’s a drop-in design, so you don’t need a gunsmith or a bench full of tools. Pop out the factory hinged trigger, drop this one in, and you’re back in business. The polymer body keeps weight down, and the pivoting safety functions exactly like you’d expect—positive engagement, no mush. At $55, it’s one of the more affordable ways to tighten up your trigger pull on these S&W platforms without sending the gun off for machine work.

We’re a licensed FFL dealer here at Tactical Arms Depot, and we ship to every state that allows firearm parts and accessories. That includes the usual suspects like Texas, Florida, and Arizona, plus states with stricter laws like California, New York, and Illinois—just make sure your receiving FFL is on file and ready. No fuss, no runaround. If you’ve got a Sigma or SD series pistol and you want a trigger that feels like it should have come from the factory, this Apex Tactical drop-in is the way to go.
