Description
Bruce Gray designed our custom P-Series Fat Custom Strut System to help bring another Grayguns custom gunsmithing service to the drop-in parts market.
For more than 40 years, Bruce has been modifying factory struts to eliminate the typical double-action crunch caused by the sharp edges and tip of the strut.
The custom strut system fully supports the main spring, reducing friction, spring bowing, and fatigue. The struts are cut using a precision EDM process, hand-finished, and heat-treated to the proper hardness.
A durable seat that is machined in-house is paired with the upgraded strut. It is made of aircraft-grade aluminum and anodized. These struts are indestructible and guaranteed for life.
This complete system also includes our custom P-Series Master Spring Set to help reduce your pull weight for full tuning options. The kit contains a 17-pound spring (red) and a 19-pound spring (blue).

Works great in conjunction with the ELS kit.
Paired this with the short reset sear and the enhanced leverage trigger kit for a refresh build on an early 90’s 226. Huge decrease in take up, creep, DA and SA pull weight.
Installed Strut/Base in P226 Stainless Elite after ELS Hybrid trigger system with Wolff 17lb hammer spring and competition sear spring. Smooth approx. 6.7 lb DA pull, < 3 lb SA pull, much improvement over factory parts.
Completely changed how my DA pull feels. So smooth. Thanks GG!
I really like the kit and how it reduces the grit and trigger pull. I found that the blue strut spring just isn’t giving me reliable primer strikes, so I had to remove it and re-install the stock spring.
