If you’re carrying or depending on an S&W SD or SDVE in .40 S&W, you already know the factory trigger leaves room for improvement. The Apex Tactical 107120 Spring Kit is a direct, no-nonsense fix. Made in the U.S. by Apex Tactical, this kit replaces the three most critical springs in your pistol: the trigger spring, striker block spring, and SD striker spring. The result is a noticeably smoother trigger pull with a shorter, more positive reset. No guesswork, no permanent modifications—just drop-in reliability.
We stock this kit because it works. It’s designed for duty and carry use, meaning it holds up under the conditions Alaskans actually face. Whether you’re running drills in the Valley or keeping a firearm ready for home defense in Anchorage, this spring kit tightens up your trigger without compromising safety. It can be used as a standalone upgrade or paired with the Apex SD Polymer Action Enhancement Trigger for an even better pull. At $27.50, it’s one of the most cost-effective performance upgrades you can make for your S&W SD/SDVE .40.
Alaska Gun Shop is a licensed FFL dealer based in Anchorage. We ship to all 50 states via FFL transfer, so no matter where you’re located, we can get this kit to your local dealer quickly. We don’t sell junk, and we don’t pad descriptions with hype. This is a solid, functional part from a manufacturer that knows what they’re doing. If you want a better trigger on your S&W SD/SDVE .40, this is the part to buy.
