The Loadout Room: GGP Glock Slide - Beyond Perfection

February 1, 2018 | Rick Dembroski

Grey Ghost Precision is a Lakewood, Washington based manufacturer that is most well known for making a nice selection of AR-15 rifles to fit the needs of Law Enforcement, Military Personnel and responsible armed citizens. The company makes rifles and uppers in the most common rifle cartridges used on the AR-15 platform, ranging from 6.5 Creedmoor all the way up to the full powered .308 Nato. While you may already be familiar with the company and their stellar reputation for quality, what you may not know about them is that they also produce aftermarket slides for several varieties Glock pistols.

Not long ago the team over at Grey Ghost Precision was nice enough to send us one of their G17 Glock slides that features a insert to support the Trijicon RMR pistol optic. Since we have just started a new cheap Glock build dubbed Operation Glockenstein I was very excited when the slide was offered up to me. The timing of these events has resulted in the launch of a series of articles that will review all of the components used in this build. The first of these components is the slide we are featuring today. The market for pistol optics is red hot and it’s nice to see more manufacturers like GGP getting into the market, more manufacturers equals more competition, which of course means better deals for consumers. Let’s take a look at the Grey Ghost Precision G17 V1 RMR slide for our Generation III Glock 17, and see why our readers should take notice.

Initial Impressions

My initial impressions of the Grey Ghost Precision slide have been overwhelmingly positive. There are a ton of small details that the company has gotten right that add to the overall feel and effectiveness of the test slide we were fortunate enough to get. When I first opened the package the weight of the slide was the first thing I noticed, the slide felt heavier than other stock Glock slides I have handled. This might be because of the 17-4 Stainless Steel that it’s manufactured from. Stainless steel is heavier than carbon steel and has a lower strength to weight ratio. There’s alot of science and match behind it all.

Now that we briefly touched on the metallurgy and perceived weight of the slide lets take a look at the feel and details of it. There are angled serrations that go completely through the slide at both the 3 and 9 o’clock positions. These are to assist the user in weapons manipulation drills and lighten the slide a tiny bit. The cuts themselves are functional and add to the ascetics of the slide without going overboard or compromising it’s structural integrity. There are an additional six serrations on the top of the slide just behind the front sight post. These differ from the other ones in that they do not go all the way through the slide and are cut horizontally instead of at an angle like all of the other serrations on the slide.

Assembly and Sight Selection

After looking over the fit and finish of the slide and the previously described details I set out to finding the necessary components to complete the slide. Grey Ghost Precision sends the slides stripped so that the user can add their favorite components to finish it off. Since I like simple and affordable I contacted my local gun shop Eagle River Gun Cache and Chugach Custom Gunworks LLC to hook me up with the parts I lacked. A little conversation and a 1/2 hour later a Lone Wolf Distributors completion kit and a set of Trijicon night sights were installed on the slide. The slide was complete and ready for testing.

This is where the only snag in the entire operation happened, I was unable to mount the Trijicon RMR red dot optic to the GGP slide because the screws I have were too long. Once I realized this was an issue I quickly sent an email to the customer service department of Grey Ghost Precision to request a set of screws that were the appropriate length. The issues with the screws only means that I can’t test this slide with the RMR attached, it doesn’t stop the evaluation of the slide while using the Trijicon hard sights in any way.

Moving past the RMR issue, once the slide was assembled and fixed on the pistol I began to run some drills with it and see how the gun felt with the new heavier slide in place. The angled serrations at the rear of the slide are cut deep into the slide and really dig into your fingers even while wearing gloves. This isn’t a negative feature or comment at all, in fact it should be taken as a positive note. The groves are deep and aggressive but not obnoxiously so, they allow the user to grasp the slide firmly even while wearing gloves or while your hands are wet or slippery for whatever reason.

Overall the Grey Ghost Precision is a well built slide that combines solid engineering, good aesthetics, and functionality all in one package. While the price of the slide may set some people off, for shooters looking for a slide that allows you to run a Trijicon RMR red dot optic and retain your stock sights, this might be the perfect slide. When you stop to compare the Grey Ghost Precision Version 1 RMR with other manufactures on the market you see that their pricing is pretty much in line with their competition.

The market for red dot optics of all types for pistols is expanding more each week, that being said the market will continue to fluctuate in both price and available options. This will mean it will continue to be a buyers market for the foreseeable future, so there is plenty of time to research companies and options. I would like to take a moment to thanks the team at Grey Ghost Precision for sending us this slide to demo, I’ve looked at a few other RMR slides on pistols in local shops and I will say that the GGP slide has a much higher quality build and design than ones I have seen. If you are in the market for a new slide for your Glock 17 or Glock 19 and want one that is cut to support the Trijicon RMR red dot, then Grey Ghost Precision is the first place I would stop.

If you are a competition shooter or running an optic on your pistol, we want to hear from you. What brand of optic are you running and what slide combo works best for you ? What combo hasn’t worked ? I personally am just starting on this journey of shooting pistols with optics so I am personally and professionally curious as to what set ups others are using. Check back in the near future while I document the planned 1400 round test of the Grey Ghost Precision upper and Trijicon combo and learn the ins and outs of shooting pistols with optics.

Ever since I was a kid, I’ve dreamed of one day having an AR chambered in the venerable .300BLK caliber. That heavyweight bullet flying out of the familiar 5.56-sized brass just screams awesomeness. Its terminal ballistics rival the 7.62 at short-to-intermediate range, making it ideal for engaging targets at those distances. The heavy bullet is makes it perfect for running as subsonic loads, and well suited to firing from suppressed guns. It’s just a cool round.

Ok, so maybe I haven’t wanted it since I was a kid. It hasn’t really been around that long (I’m older than I appear). And while all the rest of that is true, the .300BLK round still suffers from the single biggest drawback that ammo can really have: cost. Even today in the post-scare market, I have no trouble finding quality brass 5.56 ammo in the range of thirty to forty cents per round. Unfortunately, the cheapest retail pricing I see regularly for .300BLK is closer to $.85 per round. That cost is tough to justify, if you’re not reloading ammo yourself. That’s a whole other topic for another time.

All that being said, I still have plans to build or buy an AR in that caliber at some point. So you can imagine how pleased I was when I heard that the fine folks over at Grey Ghost Precision were getting ready to unveil a new variant of their Specter rifle chambered in .300BLK. As luck would have it, a prototype just happened to be floating around my town recently, and I was fortunate enough to get my grubby mitts on it to try it out a bit.

AMMOLAND: Geoscale GLOCK17 Slide Review

AMMOLAND: Geoscale GLOCK17 Slide Review

Reviewed by Tyler Hutch

Alright ladies and gents, take a knee, face outboard and grab some water – it's time to talk GLOCK slides. Let's get down to business. Recently I was invited to do some work for the legendary, Grey Ghost Precision. I've known for some time that GGP is exceptionally end-user centric and like any gear guy, I was excited to be part of the team.

One blistering afternoon, I rolled up to “The Farm” and spotted a visual on a dust plume from a black SUV advancing on my location. Upon its arrival to my location, I connected with GGP CEO, Casey Ingels, and Vice President, GW Ayers who, like Santa Clause, arrived with a truck full of brand new, precision GLOCK slides. Almost instantly, I was handed a Grey Ghost Precision Geoscale GLOCK17 Slide and instructed to run the gun as hard as I possibly could, like I “normally would.”

The first inspection of the pistol revealed a precision milled slide, cut to within only a few ten – thousandths of an inch, the ever-coveted front and top cocking serrations, and a G10 GGP cover for the RMR cut. Sure, it's the hotness, but I've got Marine in my blood and I could probably break a bowling ball in a padded room.

Of the many choices for an AR-10 that exist on the market, I have been unimpressed with most. The system still seems fickle in comparison to the AR-15 style guns competing for my dollars. Having shot many of these variants over the years, to include the M110 currently fielded by the Army and Marines, it boggles my mind why so many of the 7.62 guns will not fire as reliably or as accurately as the AR-15. My stance on the AR-10 has been firm: I will not buy one that cannot survive the abuse I know it will be subjected to under my ownership. To this day, I remain without an AR-10 type rifle in my collection. After shooting this new rifle by Grey Ghost Precision, however, that just might change.

The ability to shoot .308 quickly and accurately is very attractive and is desirable for many different applications. I for one, would love such a rifle that shot 1 MOA, and would continue to do so over a long service life. Having the opportunity to recently shoot the new GGP Specter Heavy, I was surprised to find myself really liking the design. Build around a 7075-T651 billet upper and lower, the Specter Heavy runs more like a 5.56 gas gun than a 7.62 boat anchor.

Overall, the Specter Heavy is set up as a carbine, with a collapsible stock and shorter barrel. These features combined with the lightweight suggested more recoil and muzzle rise then most AR-10 variants I’ve shot over the years. With my first shot, that proved to be wrong. Shooting the rifles suppressed and unsuppressed, standing or prone, the recoil felt more like a 5.56 than a .308! Shooting hammered pairs, NSR and Failure-To-Stop strings at 25 yards was as fun as it was easy. Proned-out and shooting 100 yards, quick controlled pairs was easily achieved off a simple rest. After making adjustments to the Vortex scope, I was able to bust multiple clay birds in only a few seconds with targets remaining in my view. The “bounce and hop” of other 7.62 semi-autos seemed nonexistent on this carbine. I shot several hundred rounds of ammo through the various Specters, with zero issues.
