Grayguns Fat Custom Strut System - Sig Sauer P Series
The Grayguns custom-designed Strut System fully supports the main spring, reducing friction, spring bowing and fatigue. The design eliminates the typical double action “crunch” felt in OEM pistols. This full system also includes our custom P-Series Master Spring Set, to help reduce your pull weight for full tuning options.
The SIG P-Series Fat Custom Strut System was designed by Bruce Gray 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.
In his new design, the fat strut fully supports the main spring which reduces friction, spring bowing, and fatigue. The struts are cut using a precision EDM process, hand finished, and heat treated to the proper hardness. Paired with the upgraded strut, is a durable seat machined in-house out of aircraft grade aluminum and anodized. These struts are indestructible and guaranteed for life.
This full system also includes our custom P-Series Master Spring Set, to help reduce your pull weight for full tuning options. Includes 17 pound spring (red) and 19 pound spring (blue).
The system is compatible with the E2 style grips, as well as most older style grips. The system fits most of the following SIG DA/SA pistol variants:
These parts are intended for installation by a qualified armorer or gunsmith. In some cases professional fitting will be required by a trained, qualified armorer/gunsmith who is very familiar with the pistol’s action.
