NDZ Reduced Power Recoil Spring Kits upgrade a range of Gen 4-5 models and provide a decisive advantage for Glock owners. Special features include a rigid stainless-steel body that improves lock up by completely removing "guide rod flex", as well as a hex screw removable tip that allows the user to choose various spring weights that will calibrate the ammunition to their firearm.

Included in this Kit:

• ( 1 ) - Black Anodized Steel Gen 4-5 Guide Rod Adapter.
• ( 1 ) - Stainless Steel Guide Rod with hardware.
• ( 1 ) - 3/32" Allen Wrench.
• ( 1 ) - 13lb ISMI Reduced Recoil Spring.
• ( 1 ) - 15lb ISMI Reduced Recoil Spring.

The NDZ Glock Generation 4-5 Adapter Ring installs under the retention end screw thereby making up the difference of space in the front of a gen 4-5 slide as well as retaining the spring accordingly.

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.

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

What Recoil Spring Weight do you Need?
