Questions & Answers

You advertise this slide as being RMR compatible, but does that include the recoil bosses? Will the shims reduce stress on the screws? Manufacturer Answer

The slide is cut for the RMR, DP pro, and Sig Romeo1/Romeo1Pro - the reason you can mount so many optics is because we do not use recoil lugs, we use friction to reduce stress on the screws! Having a very tight hold on the optic through superior tolerances reduces strain on the screws, the slide itself is helping to hold the optic on! To answer your other question, the shims simply facilitate mounting different optics tightly to our slides. Please email in to Service@greyghostprecision.com if you need more information!

I have an sig p320 m18 California complaint with a mischief machine p320 lower my barrel length is 3.9 inches and using a Romeox red dot. Will it fit Manufacturer Answer

Lot of questions here, short answer is yes.
1. Yes this should fit any P320 FCU, but your california compliant barrel (LCI) will not be functional in this slide, as you'll have to omit the LCI part of it.
2. Our compact slides are of the 3.9" size
3. Romeo X will fit on our slides, but does need custom screws and a different shim - please email in to Service@greyghostprecision.com if you need more information!

GGP quality control is lacking by Andy, March 27, 2022

Product Info for Grey Ghost Precision Sig P320 Version 1 Slide

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 P320s ability to be custom tailored to the individual users 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 GGP320C 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. The GGP320C is a drop-in install that comes with all the enhancements that professional handgun shooters have come to expect from Grey Ghost Precision.

Please Note : All sights should be installed by a gunsmith.
