The Smith & Wesson SD and SDVE pistols are known for being reliable and affordable, but their factory trigger is a common gripe. It's long, gritty, and heavy right out of the box. Apex Tactical built this kit specifically to fix that, bundling their Action Enhancement Trigger together with a complete spring kit so you get every part needed in one box instead of buying pieces separately.
When properly installed, this kit trims trigger pull weight by roughly two pounds, cuts pre-travel by about 20 percent, and reduces over-travel by around 10 percent. The result is a smoother uptake, a cleaner feel through the pull, and a more positive reset for faster follow-up shots. Owners often describe the difference as night and day compared to the stock unit, with one common comparison being how much smoother the squeeze becomes all the way through the stroke. The Apex trigger also features a center-mounted pivoting safety that keeps the factory safety values intact, so you're upgrading feel without giving up the built-in protection.
This kit is made for the classic SD and SDVE series, covering the SD9, SD40, SD9VE, and SD40VE in 9mm and .40 S&W. It does not fit the older Sigma series, and it is not compatible with the newer SD 2.0 pistols since that fire control group is a completely different design. Inside the package you'll find the Apex Action Enhancement Trigger plus the trigger return spring, striker block spring, SD striker spring, and sear spring.
Many owners handle this install at home using Apex's own instructional videos, and plenty of first-timers report success without a gunsmith. Depending on manufacturing tolerances between your specific trigger and frame, a little material may need to be filed from the trigger's overtravel stop to get everything seated right. Apex walks through that step in their frame reassembly video, so keep a small punch and a file handy and take your time. If you'd rather not tackle it yourself, a qualified gunsmith can knock it out quickly.
No, this kit is built for the classic SD and SDVE series only, including the SD9, SD40, SD9VE, and SD40VE. It does not work with the newer SD 2.0 pistols because that model uses a completely different fire control group. It's also not compatible with the older Sigma series.
Plenty of owners install it at home following Apex's instructional videos, and even first-timers report good results. Depending on the tolerances of your specific trigger and frame, you may need to file a small amount of material from the overtravel stop for proper fit. If you're not comfortable with that, a gunsmith can handle the install quickly.
When properly installed, the kit reduces trigger pull weight by roughly two pounds compared to the factory setup. It also trims pre-travel by about 20 percent and over-travel by around 10 percent, so the whole pull feels lighter, smoother, and cleaner.
Yes. The Apex trigger uses a center-mounted pivoting safety that maintains the factory safety values, so you get a much better trigger feel without sacrificing the built-in protection your pistol came with.
