Apex Tactical 107120 Spring Kit – .40 S&W S&W SD / SDVE
Stock #: 107120 | Price: $27.50

If you’re running an S&W SD or SDVE in .40 S&W and you’re tired of that gritty, heavy factory trigger, this spring kit from Apex Tactical is exactly what you need. Apex is a well-known name in the firearms industry for a reason—they build parts that work, and they build them to last. This isn’t some gimmick or quick fix; it’s a solid, duty-grade upgrade that’ll make your pistol feel like a different gun.

The kit includes three springs: the trigger spring, the striker block spring, and the SD striker spring. Install them together or combine with the Apex SD Polymer Action Enhancement Trigger for even better results. Either way, you’ll notice a smoother pull, a more defined wall, and a crisp, positive reset. It’s not about making the trigger lighter just for the sake of it—it’s about making it more predictable and controllable, especially under stress. That’s why this kit is designed for duty and carry use.

Here in Des Moines, we know a thing or two about practical shooting. Whether you’re heading out to the range south of town or keeping something reliable for home defense, you don’t want a trigger that fights you. This spring kit cleans up the slop and takes out that stacking that plagues the factory setup. It’s a simple, affordable fix that makes a real difference.
