Grey Ghost Precision Glock 19 Slide

Written by: Kenny Ortega

It seems like everyone is making Glock slides these days. Walking the aisles at the 2018 NRAAM and exhibits this year, glock slides were plentiful. As I was perusing the wares at the Tactical Tailor booth, I saw that their sister company, Grey Ghost Precision, was sharing the booth with them and had slides and barrels on display. I happened to get the opportunity to chat with the Marketing Guru at the Grey Ghost Precision, GGP, side of the booth as I ogled some of the slides available there.

At first glance, I noticed that the slides were not overly adorned with features that didn't offer any benefit other than aesthetics. Unlike most slides at the show, they were made to perform and look good, not just look good. There is an elegance to a product that is made to perform first and look good second. Who cares how good it looks if it doesn’t do what it’s supposed to do? At first glance, it appears that Grey Ghost got both areas right.

I had a number of questions for the marketing guru and after some discussion back and forth, he offered to send me a unit for review. Of course I said yes, their products were impressive. When the slide arrived, I was pleasantly surprised to find that he included one of their threaded barrels as well. That was a bonus that I had not expected. The slide that I chose was the Version 1 as it offered a bit more traction for slide manipulation. That factor became very important to me after another slide that I used to carry failed miserably in that area.

Some time ago, I purchased this slide from Zev and it had great visual appeal albeit it at a high price tag. Although, after running the slide on my gun under tough conditions, I reverted back to the factory slide as it proved more functional under real world conditions. The real test with the GGP slide would be whether it can overcome the shortcomings of a more well known and higher priced race gun slide. The only area that the GGP slide didn't surpass the race gun slide was in the flashy looks department. This comparison is a bit unfair though, it’s like comparing a Corvette to a Jaguar. Both are good looking cars but the Jaguar has a reputation for failure and requires expensive maintenance. GGP made a Corvette. It runs and looks good, at a fraction of the cost.

First Impressions

Upon opening the box, I noticed that the slide was packaged nicely and came with assembly and RMR installation instructions. Also included were the proper length screws for use with an RMR. Closer inspection showed a slide that was well machined, all the lines were crisp and sharp, there were no tool marks that I could see. The finish was deep and even. Overall, the slide had the look of a quality product and not something that was slapped together and rushed to market like many others. I felt that this slide was something I could trust and have complete confidence in. The slide did come stripped so I had to order some parts to complete the slide.

A couple of credit card number entries later and I was just waiting for parts to arrive. I kept all the parts stock to most closely mimic what the average builder might use. While race gun parts might have made the slide more desirable to some, I wanted to keep the budget minded builder as the target audience. The one item that I would highly recommend to complete the slide assembly is  a channel liner installation tool. Trying to install a channel liner without one is like trying to put on your socks without holding them. You might be able to do it but it’s a lot more work than it needs to be. Just spend the few bucks on the tool. You’ll be happy you did.

All the parts installed in the slide without any fitting or modification. To me, that speaks volumes. It means that the tolerances are held close to specifications on the slide, a sign of quality and attention to detail. I was glad to see that. When I went to mate the slide to the frame, I noticed that the fit was tighter than that of the factory slide and the alignment of the two had to be more precise. The slide to frame fit, while tighter than factory, moved freely and smoothly once the parts were mated. The barrel to slide fit was also tight and inspired confidence in the accuracy potential of this parts combination.

Checking the fit of the RMR cover plate, I found it to be snug and well fitted to the cutout for the sight. There did not appear to be any hand fitting of either the plate or the slide to mate the two parts. These items are obviously held to tight manufacturing tolerances with machines that have repeatable accuracy. Their friction fit was impressive. As someone who has been around machinists for decades, I know that tolerances like these are no small task without talent and expensive, well maintained, equipment. GGP obviously has both and it shows.

Range Testing

I was skeptical about how the slide would perform on my normally flawless Glock 19 frame and I was right to be skeptical, initially. The tighter than normal slide to frame fit did result in some failures to go fully into battery and failures to fire. To be honest though, I did do a sort of a torture test on the slide, I ran it dry to try and get it to fail. Using Winchester white box 115 grain 9mm ammo, not known for its reliability, and running the slide to frame interface dry initially, the slide did much better than other slides I have seen. The hiccups did cease after about 100 rounds and, with proper lubrication after that, the slide has yet to malfunction after several hundred more rounds.

In order to try and induce malfunctions, I added a TBRCI micro comp to the barrel. The slide just kept on performing flawlessly. I haven’t been able to induce a stoppage regardless of how hard I try. I have shot the slide in strong hand supported, strong hand only, weak hand supported, weak hand only, and had less experienced shooters shoot it as well. It performs with the notorious reliability of a Glock. They certainly go well together. If I had to find fault anywhere, it would have to be with the RMR. I am not a red dot shooter so I don’t shoot as well with one as I do with iron sights. That’s no fault of the slide though except that it gives me the ability to use a sight that I need more practice with. I’m an old iron sight guy and that’s a hard habit to break.

The slide/ barrel combo shot equally as well as the factory slide does with the aftermarket Silencerco barrel that I normally shoot. Having turned 50 last year, my eyes are not what they used to be and focusing on the front sight is difficult. You would think that a red dot would work better for me but I guess old habits die hard. Even with my old eyes, and other physical compensations I have to make, I was able to shoot 1” groups at 10 yards with ease. More importantly, when I ran ball and dummy exercises to simulate failures, the well defined, sharp edged serrations on both the front and rear of the slide allowed me to easily and effectively manipulate the slide. This was the biggest issue I had with the Zev slide that I ran in a recent class. That slide did not give me enough traction on the slide to clear simulated failures. The GGP slide traction was excellent and allowed me to clear the malfunctions with ease.

After discovering that this whiz bang slide that I bought, for almost twice what the GGP slide cost, would probably get me killed if I ever needed to clear a malfunction, I went back to the factory slide. Running the GGP slide in the same manner, I found that I could count on it to provide the necessary traction needed in an emergency and, even when my hands were sweaty, I could still manipulate it. The GGP slide restored my faith in aftermarket components on a carry gun. The V1 version of the slide has more aggressive texturing in my opinion while the V2 has a more aesthetic design. Either way, at a price point of $418.95 to $449.99, you can’t go wrong with either option.


GGP components are well made, aesthetically pleasing,  and reliable. The cost is on par with several other lesser known slide manufacturers on the market that try to compete solely on price. The prices are well below several other vendors that can easily venture into the $700 price range and beyond. Their threaded barrel with an MSRP of $189.99 is also a good deal. Their products, barrels included, are quality offerings and are priced well for the quality they provide. I am so impressed with their offerings that I am considering buying a Glock 43 just so I can modify it with one of their slides.

If you’re looking for a slide and/or barrel for your Glock, look to Grey Ghost Precision, you won’t be disappointed.

Rating: 8.75 Great


For a rating, I would say an 8.75. If it had been just a tad more reliable initially, I would have rated it higher.


Grey Ghost Precision G19 V1 Slide

  Once upon a time in the Pacific Northwest, Grey Ghost Precision started making Glock slides and barrels. These are for the ever growing market of aftermarket Glock accessories. Well, as luck would have it, they sent me one of their G19 slides and match grade barrel for review. Because they sent both a slide and barrel, I am discussing both of them as one.

  This slide is just beautiful! Okay, very useful also. They make the slide out of 17-4 stainless steel and black nitride coat it inside and out, hence the good looks. Since it is nitride coated, it should wear very well with even the hardest of use. It is a stripped slide, so all internal and external parts must be added. The slide I received was the V1. The V1 has angled front and rear cocking serrations. The front serrations are cut through the slide and gives a nice look of the barrel showing through. I really like how deep all the serrations are cut. You can really get a good purchase on them when cycling the slide or doing failure drills. There are also some grooves cut on the top front of the slide to help with user function. Grey Ghost also makes a V2 version that has a golfball style texture for grip. The V2's pattern does not extend through the slide. 

  I ended up mounting the combo on a Polymer 80 frame. Basically, it slides right on. The first really noticeable attribute, was how tight the lock up of the Grey Ghost barrel and slide were. Way better than any stock Glock I have used or felt. Since the slides are made to tighter tolerances, I wasn't super surprised. I don't know exactly what other magic they did, but the slide to frame fit is super tight and smooth. 

  Grey Ghost makes the slides with or without an RMR cut. The one the sent me has the slide cut for a Trijicon RMR. Rumor has it that Grey Ghost is also working on different red dot sight cuts. So, DeltaPoint Pro and Vortex maybe. I didn't use an RMR on it. But, the slide comes with a pre-installed cover plate. The cover plate is made out of G10 and has the Grey Ghost Precision logo laser engraved on it. For those of you that don't know what G10 is, it is a resin based composite used for handgun and knife grips. The non RMR slides also have the "ghost" lased on them. As does the Grey Ghost barrel, it is also engraved with the GGP logo.

I marked the "A" zone of the USPSA target, so you can get an idea of the 25yd accuracy

  Grey Ghost tells me that they have seen an average of a 30% increase in accuracy over stock. This seems to be a pretty bold claim, but I believe it. I shot an offhand, 3" 5 shot group, at 25 yards. It was consistent at that range with different types of ammo. That is really good for me with blurry sights (I have aging eyes). I also have no problem shooting a 6" plate rack at 20yds with the slide/barrel combo. When I move the target in to 7yds, it shoots one ragged hole, if I do my part. The slide functions extremely well also. I just used a stock recoil spring assembly and only had 2 problems running 165 subsonic ammo (it shoots really light and is intended for suppressor use). It runs the 165's fine now, so maybe the slide just needed a little break in period. When I ran 115, 124, and 147gr ammunition through the pistol, it functioned without a hitch. The ammo was a variety of factory, handloads, and even some +P hollow points. I have around 600 round through it as of this writing, mostly 115 and 124's. 

  Grey Ghost's barrel is also a thing of beauty. They sent a 416R stainless steel threaded barrel. Yes, threaded 1/2-28 for a suppressor or compensator. They only list black, unthreaded on the website, so ask them if you want something different, I am sure they can help you out. These barrels use a proprietary twist rate, so who really knows what it is. But, I don't think it matters because of how well it shoots all different weights of 9mm. It also uses SAAMI spec match chambers and is cut to within +/- 0.003". When combined with the tight specs of the slide, you get a wonderful shooting combo.

  I discussed how well the slide/barrel shoot. So I'll give some experiences while shooting. I have cycled the slide in the rain without feeling like my hand was going to slip off of the serrations. It is definitely better than the original small lines on a 1911. It shines while wearing shooting gloves. It almost feels like the gloves get caught in the grooves and really enhance the grip on the serrations. Performing press checks, using the front serrations, works well, if that's your thing.

 These slides and barrels are available for Gen 3 and Gen 4 G19's and G17's. I really can't say enough nice things about the barrel and slide, they are really that nice. The black Nitride is better looking than a standard Glock finish. The slide has a good functional design. So if you are in the market to modify or build a G19, definitely go check out Grey Ghost Precision and what they have to offer.
