NDZ Performance stainless steel guide rods provide a decisive advantage for all Glock owners. Special features include a rigid stainless-steel body that improves lock up by completely removing "guide rod flex". The hex screw removable tip allows the user to choose various spring weights that will calibrate the ammunition to their Glock. Our Generation 4 & 5 specific guide rods have an enlarged base similar to the stock OEM guide rods which allow for the single spring assembly to sit at a more parallel position to the barrel for better performance.
The NDZ Generation 4-5 Adapter Ring installs under the retention end screw thereby making up the difference of space in the front of a generation 4-5 slide as well as retaining the spring accordingly.
ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then the springs are heat treated, shot-peened and stress relieved after winding to enhance performance and durability.
Please Make sure you are using the correct loads for the springs or you will have cycling issues.
