FAQ:

  1. Is the flat wire spring compatible with a full length guide rod? Yes-Only with the full length flat wire guide rod (#25GRFW). The inner diameter of the flat wire spring is smaller than a conventional round wire spring requiring a flat wire specific guide rod.
  2. Is a Shok Buff required? A Shok-Buff is included but optional on the 5” flatwire guide rod. It is not recommended for use on the 4” kit since it can reduce slide travel.
  3. Can I shoot +P ammunition with this kit? Yes-since flat wire springs don’t lose their length over time like round wire springs they cushion your frame more effectively over time. Flat wire springs also compress in a more linear fashion which makes them more tolerant of a wider variety of loads and grips.

    First upgrade on Kimber 4” 9mm CDP

    Posted by Funster on Jan 8th 2025

    The 4” Kimbers use a cut-down commander length spring because the dust cover is too short, This means a service life of only 800 rounds or so. This kit lasts much longer with no danger of coil binding. Also, the intermediate length guide rod lets you take it down without a takedown tool. Perfect!

    Best Thing For My Aegis Pro Ii

    Posted by Krunchnik on Jun 11th 2016

    Replaced my factory guide rod and spring with the Wilson Combat unit and couldnt be happier.Makes take down a lot simpler-and have had zero malfunctions.I also like the thought of not having to replace springs often.I havent noticed any difference in recoil-it just works.
