NEW SLIDE, NEW PLATFORM!

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.

    GGP 320 full size slide

    Posted by Jeff on Jul 19th 2021

    Garbage product and so far even worse customer service, slide cracked pretty severely while firing standard pressure duty ammo. Upon inspection it is obviously machined out of spec in the area where it cracked. That this is bad....especially if your using as a duty pistol. Its been over a month since I sent my first of multiple emails and forget trying to call.

    P320 Slide review

    Posted by Matt on Mar 9th 2021

    Gorgeous slide, very well done! Fit and finish are great, slightly different and smaller overall dimensions from the stock slide on an m17 but that is a good thing. The ability to select multiple RDS makes it even better. Glad I made the purchase, GGP did a great job on this one.

    High quality slides

    Posted by Tyler Ziel on Feb 20th 2021

    Slides are great. Machining is clean and the finish is good. No reliability issues so far with about 4k rounds down range. Ive only mounted RMRs to my compact and full size slides but thier were no issues with fit. My only complaint is they come with allen screws instead of torx. While I have not rounded them out, I fear that eventually I will seeing as I change batterys every year. All things considered, these are fantastic slides.

    P320 V1

    Posted by Tristan on Aug 12th 2020

    Only thing I can complain about is that the screws for my RMR kept walking out but I think I got it under control. Otherwise the Cerakote looks excellent, slide cuts are super clean, and everything fits as it should..

    First, Grey Ghost has awesome costumer service! The slide is beautiful. Paired with a Grey Ghost threaded barrel. It's a work of art. Thanks Grey Ghost for your great service. I will be a repeat costumer.

    BALANCE NOT QUITE THERE

    Posted by Steve Hall on Jun 6th 2020

    This is a well machined and good looking slide. The RMR fit is tight and solid. I was not anticipating needing a shim for the RMR and the website wasn’t all that clear on that but it hasn’t been a problem. I could not find any long-term reviews online but it has functioned flawlessly so far and I have about 800 rounds through mine. The RMR screws have not backed out once. As for how it shoots, I would note that the slide gets hot fairly quickly. My personal opinion is that the slide is not that well balanced. I feel that too much material has been taken out of the front of the slide leading to muzzle rise. In other words, I have no way to verify this but I think they took out more material from the front of the slide than for the RMR cut. For the cost of the slide, I guess I was hoping it would shoot flatter for me. Overall, it looks great but I’m having some buyer’s remorse because I don’t care much for flashy looks as functionality wins the day for me. In short, I wish I would have opted for one without the window cuts. Might just be me, but that’s my honest assessment.
