If you own an S&W SD or SDVE in .40 S&W and you’ve been putting up with that gritty, heavy factory trigger, this is the fix you’ve been looking for. This is the Apex Tactical 107120 Spring Kit — straight from the manufacturer who knows your platform inside and out. We’re talking a drop-in set of three springs that smooth out the pull, clean up the reset, and keep your gun running reliable for duty or carry use. No filing, no fitting, no gunsmithing degree required.
Here’s what’s in the bag: a trigger spring, a striker block spring, and an SD striker spring. Swap ’em in and you’ll feel the difference immediately — a lighter, more consistent trigger pull with a crisp reset that lets you stay on target. Apex designed this kit to work as a stand-alone upgrade or paired with their SD Polymer Action Enhancement Trigger if you want to go all-in. Either way, you’re getting a noticeable improvement without compromising safety or reliability. That’s the kind of engineering that keeps Apex Tactical at the top of the aftermarket game.
