**NOT for use in the SIGMA Series pistols. If your gun is a SW9VE or SW40VE, this kit will not work in your gun.
**This kit DOES NOT include a sear spring. This kit is designed to work with the factory sear spring, so removal and/or replacement of the sear spring is not necessary.
Since its introduction, the Smith & Wesson (S&W) SD series has gained acceptance as an excellent handgun for duty, concealed carry, home defense, and even competitive shooting. Its performance in all of these niches can be improved with a trigger upgrade such as the SD Spring Kit from Apex.
This kit includes three springs that will take the pull weight down to five and a half pounds. After installing the kit, you'll be shooting with accuracy that you never thought possible. The trigger reset will be improved as well. All of the parts are drop-in, so you don't have to take it to your gunsmith or make permanent alterations! Give your S&W SD9, SD40, SD9VE, or SD40VE a useful upgrade with this spring kit from Apex!
