From Grayguns, a Master Spring Set for Sig Sauer P-Series handguns. The P-MSS kit is an action upgrade package designed to reduce trigger pull weight while still providing reliable primer strikes. This set includes two mainsprings, one 17 lb. and one 19 lb., and a competition sear spring.

Fits the modern P-Series handguns with a DA/SA system, P220, P224, P225A1, P226, P227, P228, P229 and P-226 X-Five Allround.

Grayguns Pink+P9 recoil spring for Sig Sauer pistols. A heavy duty P226 9mm spring for those shooting hot 9mm loads.

Also suitable to P226 .40/357 and the P220 .45ACP if using reduced power loads.

The P22xCT Classic Standard Trigger adds over-travel adjustability to our original design. Utterly indestructible, the P22xCT Classic Standard is machined from tough steel, carefully heat treated and finished in black oxide. Tight pin hole tolerances assure smooth, solid function.

Our intermediate trigger shape optimizes both SA and DA control for optimal control, and is more comfortable than the factory short trigger it replaces. Guaranteed for life against defects in materials or workmanship.

Made with love, supplied with a hex key.

Will not fit SIG Pro, X5 Allround, P225 / P6, P239 or most SAO models. Also will not fit older P220 with 8mm wide trigger.

This product was previously referred to as the P-Series Precision Adjustable Intermediate Trigger (P-SAIT).

Developed by the renowned gunsmiths of Grayguns, the FAT guide rods are designed to optimally support factory Sig Sauer, and Grayguns custom multi-strand springs for maximum service life and smooth, reliable function. Designed to the maximum nominal diameter to fit each pistol perfectly, FAT rods also eliminate the possibility of coil-jumping and damage when used with correctly-selected after-market single strand recoil springs. Grayguns FAT rods are hardened and stress-relieved to withstand a lifetime of hard use as well as being carefully polished stainless or finished in ultra-durable Super Black. Lifetime guarantee against galling, ringing or breakage. Simply put, some of the highest quality guide rods available today.

Fits Sig Sauer P220 and P226 - Super Black Finish

Bruce Gray combined the best of both worlds when he designed what we know as the hybrid trigger.

The unique face allows the shooter can take advantage of finger placement lower on the face, with the comfort of a traditional curved face. This hybrid design reduces trigger weight while preserving all mechanical safety values.

The Grayguns P320 Hybrid Trigger uses internal leverage changes to yield superior trigger pull, while supporting the voluntary upgrade’s enhanced reliability and rough handling performance qualities.

Includes our adjustable over-travel stop design to shorten reset and take out all gross over-travel. Designed for easy drop-in installation.

Specifically designed for P320s with current fire control unit components, or those who have gone through SIG’s Voluntary Upgrade Program.

Designed for hard-duty use. Our custom Grayguns SIG Sauer P320 magazine base pads are manufactured from 6061 Aluminum. Professionally finished with MIL-A-8625 Type III anodized coating. Pads go through a glass-beading process to provide a flat-black finish.

The base pad is the same thickness as the OEM SIG base pad. A relief cut on the sides enhances malfunction drills, and allows for effective one-handed reloads using the belt or holster.

The cut mirrors the normal P320 module’s and creates a cut for the X-Series modules.

Each pad features a 3-by-5 matrix. Number your mags using a Sharpie or paint pen. Additional space is available to write your initials.

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).
