    Overall Customer Rating of 28 Reviews:

    Kit and video we're self explanatory. Reinstalling the spring and pin at the end using the supplied dowel was a bit challenging as the dowel kept slipping allowing.the spring to fall.out of place. Used a small punch to hold spring in place and inserted pin from the other end, which worked out fine. Definitely lightened the trigger, looking forward to sending some rounds down range.


    Awesome results! Must have!

    This was an great improvement over the heavy as crap stock trigger pull! Well worth the effort and money! The instructions video is top notch! If you own this gun get it now!

    SW9VE Trigger Spring

    I finished using my SW9VE for the first time, after installing this kit, a few minutes ago. First, I have hated this pistol since I bought it 10 years ago. The trigger was heavy and pulled me off target 80% of the time. I wanted to like the pistol but could not get past that trigger. I found this kit and thought I would give it a try. I followed along with the installation video, and the process was extremely easy. At the range, it was like I had a different gun in my hand. I could immediately tell the difference and the accuracy showed. I would recommend this product to anyone who owns this pistol. Do yourself a favor and fix that trigger!

    S&W SD40VE spring kit

    Great. Easy to install.


    Now I like my Sigma

    I swapped the factory spring in my Sigma 40 last night. Very helpful video to do the install. I test fired this afternoon and it is a whole new gun. I used to not be able to hold on target as I worked through the 10lb trigger pull. Shot a very nice group this afternoon and will be putting in more range time on this gun now!
