Upgrade the guide rod on your Glock 19 with the new NDZ Performance heavyweight stainless steel guide rod assemblies. These guide rods are thicker than the stock guide rod and provide a decisive advantage for all Glock owners by including a thick stainless steel body that adds extra weight to mitigate recoil and completely removes "guide rod flex". NDZ guide rods also include a hex screw removable tip which allows the user to calibrate the firearm by installing recoil springs with various spring weights.
