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).

WARNING, Do not install this on your gun. It will make you hate all of your other guns! I have installed the Enhanced Leverage System with the dual adjustable hybrid trigger, The P series custom strut system with 17# spring, and the short reset trigger kit on my Sig P229 and the differance is absolutly amazing! Gray Guns reccommends for it to be installed by a certified gunsmith but I am pretty handy so I attempted to install myself and had no issues. Now I need to buy it all again for my Sig P220 Scorpion because there is no way I can continue on without it. 😉
I installed this on my Sig P226 and it was a little tricky getting the strut in just the right notch in the center of the hammer. I first used the red 17 pound spring and it lowered the double action trigger pull from 8.5 pounds to 6.5 pounds and single action pull from 3.5 pounds to 2 pounds 4 ounces. This was the average of 7 pulls with a Wheeler trigger pull gauge. I got about 10% misfires and then changed to the blue 19 pound spring and the misfire issue completely disappeared. I am considering installing one of these on my P229 that is in 40 S&W.
Needed to do the strut upgrade on my MK25, and while SIg makes a factory piece I think the Grayguns version is superior and a better value. I also upgraded to the ELS and an SRT kit. All three systems together made the gun much smoother and enjoyable. Highly recommend this strut system!
Installed this kit with the 19lb spring in my first run Sig P229 I purchased in 1992.
I really fine addition to a very fine pistol.
Awesome Product. Much smoother than even the factory Legion strut system.
Installed on early model 229 with the 17 lb spring. What a difference really smoothed up the double action trigger pull. Recommend this product buy it you will like it. Easy to install.
This with the ELS and GG sear makes DA/SA smoother than factory. Overall another great mod.
This is one of my first upgrades to my new p229. Very easy to install and eliminates the “crunch”. These parts are expertly made and make a big difference to overall performance and function.
Works fine. Easy to install. Adds weight. Slick.
This is the first mod I’ve done to my p220. It ready does smooth out the trigger pull quite a bit. With the 17# spring it’s a big improvement over stock. The SRT kit is next.
Installing the custom strut made an amazing difference to my P220. I got a DA pull of 5lb 8oz. It also enhanced the short reset that was previously installed. Thanks for the excellent parts.
Like many others have said really removes all the “crunch”, its very noticable in DA and even in SA you can feel a slight difference with a smoother break. Very high quality parts with incredibly smooth finish and the redesigned strut completely removes the spring bowing issue. Would absolutely buy again for any P22x series gun.
