Grayguns unique step-tapered design and unmatched surface finish affords easy installation with optimum recoil spring support. Proper spring support ensure maximum spring life and smooth cycling.

Grayguns’ 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.

Being made to the maximum nominal diameter to fit each pistol perfectly, our fat rods also eliminate the possibility of coil-jumping and damage when used with correctly-selected after-market single strand recoil springs.

    These guide rods are an excellent remedy for cheesy OEM rods, and add a bit of front balance. Of interest, not mentioned in the product notes is Bruce’s inspiration for these “fat” guide rods: As I recall his story, he had a slide spring escape past a guide rod out of the front of the slide, disabling his pistol – during a match! It turned out that the guide rod was somewhat undersized, whereupon he turned some new rods to maximum, i.e., “fat” dimensions. Whatever the background, I’ve never had this problem using Grayguns guide rods – and they look good, too!

    Installed this guide rod on a Sig P226 Elite Stainless. Shipment arrived fast, and it’s clear the product quality is of the highest level. I plan to add additional Gray Guns parts to further refine my Sig P226. Amazing and truly the best!

    Fat guide rod.

    Fit was perfect and closed the guide hole enough so my single coil recoil springs can be used.

    Installed this guide rod on a a P320 FCU build. Fits and functions well. I like the fact that it uses the 1911 recoil spring so I have the ability to adjust spring tension as needed.

    Absolutely awesome upgrade for my custom Sig Sauer P320 FS Pro Cut Slide Assembly, with Sig P320 FCU, Sig FS (4.7”) OEM Barrel, & WCP P320 Carry Grip Module in Black. The Gray Guns Black Magic FS Guide Rod & Recoil Spring are definitely a must! Prefect fit, exceptional quality. I installed another set on my Sig P320 FS OEM as well. Highly Recommend 👍

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.
