Sig P320 Rear Slide Plate

NDZ Performance has been manufacturing Custom Rear Plates for nearly a decade. 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.
