Due to the change in laws we are no longer able to ship to WA

The adoption of the P320® platform by the U.S. Military, as well as many Law Enforcement agencies, professional lead farmers, competition shooters, and firearm instructors led to the development of a new line of GGP aftermarket slides. After all, the P320’s ability to be custom tailored to the individual user’s preferences in grip length, grip size, as well as slide length and sight radius are all highly desirable features. Why stop there, when you can have even more customization options when upgrading to a drop-in GGP320 slide. 

Just like our GGP17/19 and SPG43 slides, these GGP320 slides offers enhanced aesthetic features, increased grip serrations and an improved coating without compromising function. We also took our hybrid MRDS optic cut and added a third option, the SIG ROMEO1. Now you have to option to use a ROMEO1 as well as a Trijicon RMR or Leupold DeltaPoint Pro right out of the box without using bulky adapter plates that only raise the optic further above the bore axis. Available in Grey or Black DLC finish for corrosive and abrasion resistance, the GGP320 will also be available in FDE Cerakote. The GGP320 is a drop-in install that comes with all the enhancements that professional handgun shooters have come to expect from Grey Ghost Precision.
