About this product
If you’re running a Smith & Wesson SD9, SD40, SD357, SDVE9, SDVE40, SDVE357, or a Sigma, you already know the factory hinged trigger leaves something to be desired. That’s where Apex Tactical comes in. They make this 107003 Action Enhancement Trigger — a solid body polymer drop-in that replaces that hinged setup with a center-mounted pivoting safety. No gunsmithing required. No headaches. Just a straight swap that’ll tighten up your pull.
Here’s what you’re getting: Apex Tactical shaved about 20% off the pre-travel and 10% off the over-travel compared to stock. That might not sound like a lot on paper, but when you’re on the range or behind the counter, it’s the difference between a sloppy squeeze and a crisp break. The trigger face is rounded and smooth — no sharp edges digging into your finger. It’s comfortable, even on longer sessions. And because it’s polymer, it’s tough without adding unnecessary weight.
This trigger works great as a standalone part, but if you’ve already got an Apex SD or Sigma Spring Kit installed, you’ll really feel the difference. The combination tightens everything up nicely. Whether you’re running a carry piece or a range gun, it’s a solid upgrade for the money — $55, and I’ll tell you straight, it’s one of the better value mods you can do for these platforms.
