Grayguns unique step-tapered design and unmatched surface finish afford easy installation with optimum recoil spring support. Proper spring support ensures 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.

    Works fantastic, looks very nice.
    The only issue I have with this is no matter what slide/barrel/grip module combo I use the takedown lever gets stuck on the oversized guide rod… the only way to rotate the takedown lever is to flip the gun upside down and place the takedown lever on a hard surface and push all my weight down to get it to rotate. GG says this is normal because it’s oversized? I’ve tried so many variations: push up, pull down, wiggle and jiggle, etc. but I can see the takedown lever starting to develop a “worn spot” where it’s being forced to overcome the larger guide rod.

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

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.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
