If you’ve got a Smith & Wesson SD or SDVE in .40 S&W, you already know the factory trigger leaves something to be desired. It’s gritty, the reset is mushy, and that heavy pull doesn’t exactly help your split times at the range. That’s where Apex Tactical comes in—they’ve been fixing factory triggers for years, and this spring kit is a simple, affordable way to tighten things up without swapping out the whole fire control group.

This Apex Tactical 107120 spring kit is designed for duty or carry use, meaning it’s reliable enough for everyday carry but still smooths out the pull and gives you a clean, positive reset. It works as a stand-alone upgrade, or you can pair it with the Apex SD Polymer Action Enhancement Trigger for an even better feel. Either way, you’re getting a noticeable improvement in trigger consistency—less stacking, less creep, and a reset that actually lets you know it’s reset.

The kit includes three springs: the trigger spring, the striker block spring, and the SD striker spring. Installation is straightforward if you’re comfortable with a punch and some patience—just take your time, follow the included instructions, and you’ll be good to go. No gunsmith required, but if you’re not sure, any local shop with a bench can handle it in a few minutes.

Here in California, we know the value of a reliable defensive firearm. Whether you’re running a duty gun or a home defense piece, a smoother trigger means better accuracy under stress. And at 27 bucks, this kit is one of the best bang-for-buck upgrades you can do to an SD or SDVE. No fluff, just better performance.

CalGuns Depot is a licensed FFL dealer, and we ship this kit to all 50 states—no restrictions, no hassle. Add it to your cart, and we’ll get it out the door quick. If you’ve got questions, give us a call or stop by the shop. We know our stuff, and we’re happy to help.
