The NDZ RPR Kits 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. The NDZ Generation 4 Adapter Ring installs under the retention end screw thereby making up the difference of space in the front of a generation 4 slide as well as retaining the spring accordingly.

Important: Please make sure you are using the correct loads for the springs or you will have cycling issues.

Note: We recommend the use of Blue Loctite on the hex screw threads when switching out springs. This will provide a firm hold and still allow easy removal when necessary.

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.

Note: NDZ always recommends any part be installed by a qualified and trained gunsmith. NDZ promotes the use of safety practices and gear when working on any firearm.
