    Great Value / Easy Installation

    Posted by Safety Oriented Solutions LLC on Jul 11th 2026

    Received the Custom-Tune Spring kit quickly, replaced the factory springs and felt the difference immediately. Significant improvement in the responsiveness of the gun. The gun now has a clean pull in double action and an extremely responsive single action break. Made a huge difference.

    Excellent Performance

    Bought these for my 686-6 and 629 Mountain Gun. Put the hammer spring an 12 lb rebound and worked perfect. No light strikes.

    Quality Upgrade

    Posted by Matt R. on Jun 7th 2025

    Had this installed in my dad's S&W K-frame with the 14# spring. Trigger pull in double action is much smoother than before, and my accuracy also improved. A great upgrade for the money.

    Great!

    Received today, installed with the 12# spring and sent 100 rounds down range in my Model 10-10 with no issues! Much better trigger and the install was pretty straightforward.

    Does not work on a no-dash, square butt 629

    Posted by Adam the Great on Mar 28th 2025

    The hooks on the factory mainspring in my no-dash, square butt 629 wrap around further. The Wilson hooks don't wrap around as far the the spring kept slipping off the hammer. I suspect these are made for a round butt frame, which holds the spring at a sharper angle than the square. The 13# return spring wouldn't return the trigger. I'm saving the parts though and using them as an excuse to buy a more modern, round butt revolver. 4 stars as these should include a disclaimer about square vs round butt fitment.

    Does not work for all L models

    Posted by Rick on Dec 12th 2024

    Bought this for my SW 686 pro and the main spring does not work with this model. This frame is an L frame so according to WC it should work. I wasted a few bucks buying the kit because all I ended up using was the reduced power rebound trigger spring, which did help some. If you have this model just get the rebound spring only. I am using the 13# and it did reduce it some.
