NDZ Performance barrels are designed to work seamlessly with factory-new, high-quality SAAMI spec +P ammunition. However, they are not recommended for use with "+P+" or "++P" over-pressure ammunition, as well as reloads or rounds utilizing substandard components. Using +P ammunition should only be used in moderation, particularly with smaller or lighter handguns, as these firearms and their components may undergo accelerated wear compared to larger or heavier handguns. Furthermore, make sure to do your research on the ammunition that you will be using. Exceeding 1300 FPS with your ammunition will nullify the warranty.

Warranty - We will replace any barrel found to have material or manufacturing defects. Any modifications to the barrel and or the use of reloaded ammunition will void the barrel warranty.


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.


Warning: Installing a threaded barrel on your firearm may violate your state's laws.
