NDZ Tuner Packs for Glock Gen 4 19, 23, 32, 38 Gen 5 19, 19X, 45

The 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 his gun. Used by Law Enforcement as well as competitive shooters worldwide these guide rods will not chip or crack like the factory plastic guide rods are prone to do. Will not damage or wear the polymer Glock frame and is guaranteed to provide a lifetime of reliable service. For first-time use or when changing out springs it is recommended to use Blue Loctite on the hex screw threads. This will provide a firm hold and still allow easy removal when necessary.

A spring too light could cause feeding failures and damage your firearm, and a spring too heavy can cause your muzzle to nose-dive and possibly cause difficulty reacquiring your target in a timely manner. This tuner pack is designed for you to find the best guide rod spring to match the pressure of your load, to avoid jams and misfeeds.

Please use the proper tools like a vice and This NDZ Performance Guide Rod Spring Removal Tool here when switching out your springs.

    Great pack

    Appears to be well made. Just keep the packaging for the springs so you can easily identify which one is which weight.

    Only complaint is that I the spring weights weren't very clear. The item # seemed to have them on the end of the string on digits, but it was not super clear. Great product though.
