Sig P320 Rear Plates

 

NDZ Performance has been manufacturing Custom Back Plates for nearly a decade and now we have designed a plate for the Sig Sauer P320 models in 9mm, .357 SIG & .40 S&W Calibers. Our plates are machine manufactured from T6 6061 aluminum for proven durability and strength, and then electrically anodized, creating a hardened film over the plate that is much more resistant to weathering and corrosion. Anodizing also has a side effect of changing the color of the part so we can offer these parts in over 9 different colors. If you're looking for even more customization, we also offer an image library with over 1500 images to choose from that we can laser on any anodized aluminum product!

 

These Rear Plate Upgrades also fit the P320-M17 & P320-M18!

 

(*LZ) means that this product is capable of being laser engraved for personalization.
