Sig P320 FAT Stainless Steel Guide Rod by Grayguns

Grayguns unique step-tapered design and unmatched surface finish affords easy installation with optimum recoil spring support for 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.

Unlike other, cheaper products, our FAT rods are made from proper material, hardened and stress-relieved stainless steel to withstand a lifetime of hard use, are carefully polished or finished in our ultra-durable Super Black, and are guaranteed for life against galling, ringing or breakage.

No Grayguns guide rod has ever scored, chipped or broken, but we guarantee them for life just the same.

A lot goes into such a simple-looking part, and there are none better.

* Our P320-F (Full-Size) and P320 X-Five (Full Size) guide rods include a 15 pound 1911 recoil spring

Guide rods are not caliber specific. Use the appropriate recoil spring for your caliber.
