Grayguns’s 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 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.

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

NOTE: P320 X-Five (Full Size) guide rods include a 15 pound 1911 recoil spring.
