An EGW one-piece tungsten guide rod for STI pistols. Tungsten is much denser than steel, so the rod adds weight under the dust cover, which helps keep the muzzle flatter during recoil and speeds up follow-up shots. It replaces the factory recoil spring guide rod. Compare the fitment details below with your firearm before ordering.
