Glock 19X Review: The Crossover Champ?

Rating: 7.5/10 – The Glock 19X is an exceptionally reliable and accurate “crossover” pistol that excels as a duty weapon and home defense gun, but its full-size grip makes concealed carry challenging for most users.

The 19X combines the Glock 17’s comfortable full-size grip with the Glock 19’s more concealable 4-inch barrel, creating a unique hybrid that delivers outstanding performance. After 2,000+ rounds of testing, it proved utterly reliable with zero malfunctions while delivering impressive accuracy thanks to the Glock Marksman Barrel. The distinctive Coyote Tan finish makes this the first factory-colored Glock.

This pistol shines for law enforcement, home defense, and range use where its high capacity (17+1 or 19+1 rounds) and excellent ergonomics matter most. However, the full-size grip creates significant concealment challenges, and the 2018 design lacks modern features like optics-ready capability. The unique flared magwell also prevents compatibility with standard G17 magazines.

At $550-$600 street price, the 19X offers solid value but faces strong competition from the newer G45 MOS, which provides similar performance with more modern features. The 19X makes sense if you specifically want the Coyote Tan finish or the historical significance of nearly becoming the Army’s standard sidearm, but most buyers will find better options elsewhere.

Pros

• “Mullet” set up gives you more capacity and control
• Shorter slide enhances concealability
• Unsurpassed reliability

Cons

• Unique magwell hampers mag cross-compatibility
• No optics cut or Gen5 front slide serrations
• Beginning to feel dated

Design & Purpose

Dubbed a “crossover” by Glock, the G19X is the first Glock that blends a standard-sized Model 17 grip with the more compact Model 19 slide and barrel for an Austrian take on a hybrid pistol.

This “mullet” concept gives the user a full grip, which enhances shooter control, makes it easier to handle from a carry position, and is capable of a 17+1 (flush fit) and 19+1 (gently extended) magazine capacity, with the better concealability of a pistol with a 4-inch barrel.

Developed along the same timeline as Glock’s new Gen 5 models it has many of the same features such as the updated and very accurate Glock Marksman barrel and new trigger system.

The first-ever factory-colored Coyote Tan Glock, the frame mimics the other Gen 5 models in the respect that it has no finger grooves, a recessed thumb rest, and interchangeable frame backstraps.

Unlike just about any other factory Glock, it comes standard with a flared magwell with a distinctive front “toe” to allow for faster loading in rough field conditions such as in a desert, along with a lanyard loop, the latter a feature requested as part of the XM17 MHS competition.

This puts the Coyote Brown G19X in an interesting ballpark, being large and durable enough for serious duty or field use, fully capable of running a 3-gun competition, well able to clock in for home defense, or, with the right holster, be carried every day for personal protection.

In short, it is a modern take on the old Colt Commander concept, but with much better reliability not to mention an expanded magazine capacity.

Physical Features & Build Quality

Glock has never had a reputation for building junk. Other than a shrinking and aging cohort of dinosaurs that just despise polymer-framed and/or striker-fired handguns on principle, most folks who know firearms recognize and respect Glocks for their build quality.

Just about every torture test– some legendary– that can be done to a handgun has been done to a Glock and they just can’t be killed. Heck, Chuck Taylor has put well over 300,000 rounds through his G17 in the past three decades. There is a reason these guns go thousands after thousands of rounds in the rental game, where regular “burn down” by legions of users is a real thing.

The fit and finish, internal parts durability, and functionality of my test Glock 19X were never in question throughout the 2,000 rounds I have put through it. I haven’t felt the need to replace any parts and, in that period, only field stripped and cleaned it three times, roughly after every 600-700 rounds.

Controls and ergonomics

The Glock 19X, like most modern handguns on the market in America, is principally set up with controls on the left side of the grip frame for right-handed users. This makes sense, after all, as studies show that about 90 percent of folks are right-hand dominant while left-handed and fully ambidextrous people make up the rest of the population.

However, to accommodate those southpaws out there, the G19X includes ambidextrous slide-stop levers and a reversible enlarged magazine catch that can be swapped easily to the other side of the frame.

The controls were workable and laid out logically, particularly the mag release, and I found no real issue working them under normal conditions.

About the worst I can say is that, when wearing gloves, the ambidextrous slide stop lever is a little slippery, but it can be swapped out for something larger should the user want, scaling up to something like the GoGun Gas Pedal or Tandemkross Accelerator thumb ledge.

Magazines

Included with the G19X is a standard 17-round magazine of the type used by the Gen 4 G17 that fits flush in the magwell and a pair of 19-round mags that use special extended baseplates similar to those seen on a Pearce grip extension.

Like most G17-sized frames, it will accept Glock’s standard factory double-stack extended (24-round, 31-round, and 33-round) 9mm magazines as well as quality Glock-pattern aftermarkets such as Magpul’s GL9-series PMAGS in 21-round and 27-round sticks, along with their 50-round D50 drum.

What *won’t* work is standard Glock G17 Gen 5 magazines as the base plates hit the “toe” of the flared magwell on the G19X. On some other Gen 4/5 extended baseplates, the lanyard loop prevents them from seating. Also, standard 15-round G19 mags of any generation are all too short to work in the pistol.

In testing, I ran all the above through my G19X and had no problems to report other than the GL9 aftermarkets occasionally failing to lock back the slide on an empty mag.

Slide and barrel details

The slide on the G19X, other than its Coyote finish, is an almost typical Gen 5 G19 slide (except for the fact that it doesn’t have forward slide serrations) which is good as it allows for easy upgrades and parts compatibility, and the beveled front portion makes for a smooth draw from practically any holster.

The shorter slide also makes the gun faster to draw.

I swapped out a few different G19 barrels with my pistol to assess interchangeability and can report that the Lone Wolf Alpha Wolf– a 416 stainless threaded M19 barrel– and Faxon’s flame-fluted match barrel both dropped in without the need for fitting and performed fine.

However, as the standard factory barrel on the G19X is Glock’s superb new Marksman series barrel, complete with a tough-as-nails black nDLC finish and enhanced barrel rifling based on the company’s proven polygonal design, about the only reason to swap out from the factory OEM, would be if you planned to use the pistol as a suppressor host or wanted to mount a muzzle device and needed threads for that purpose.

Sights and optics readiness

When it comes to sights, the shorter sight radius makes the G19X faster on target thanks to the shorter slide, and Glock catalogs the G19X with options for standard polymer sights, steel sights, or GNS– Glock Night Sights.

However, every G19X I have seen in the wild, including mine, has the GNS sights fitted.

The GNS line is straightforward when it comes to their arrangement, fitted with a small tritium element, glowing green in low light and set in three white contrasting dots, which is a departure from Glock’s more familiar U-notch rear and front post.

The vials on the GNS were strongly illuminated in low light conditions without the sight needing to be exposed to a light source first, while in the daytime were still easy to acquire even in bright sunlight.

For height reference, mine were MH3s, which is a 6.5mm tall rear and 4.1mm front.

Controls and ergonomics

The G19X borrows the same rough textured frame surface as introduced back on the Gen 4 Glocks in 2010.

This RTF variant has been among the most popular with Glock users as it draws a balance between the kind of slippery pebbled and grenade texture of the old Gen 1/2/3 series Glocks and the hyper abrasive and short-lived RTF2.

With sections of this tall polymid texture on the front, sides, and rear of the grip, the user has 360-degree coverage, allowing the pistol to “stick” to the hand for a comfortable grip.

What the G19X doesn’t have from the Gen 4 Glocks are molded finger grooves, an element many users found disrupted their grip as their fingers rarely lined up perfectly with the mold.

Like the Gen 5s, the G19X ships standard with interchangeable beavertail backstraps in two sizes. This modularity allows the users to change the circumference of the grip to better fit their hand size, shifting the ergonomics.

While the feature is nice, I did not adjust the grip size in testing as the G19X felt fine right out of the box, even with tapping in three different shooters.

However, it is nice to know these backstraps are there if you need them and have a challenging time getting a good grip on the gun.

Speaking of which, should the texture not be ideal, there is always the old standby of stippling (have you seen what people are doing with laser stippling these days?) to make it more aggressive, or applying a bit of sandpaper to smooth the polymids down for those who find it too pointed.

Trigger & Reset

Glock’s striker-fired action has often been criticized for having a terrible trigger, something that each subsequent generation of the family tried to improve on.

The Glock 19X uses the Gen 5 trigger design, which has improved components (trigger bar, plunger, spring assembly and locking block) and I found to break at almost 6 pounds at the start of my tests and even out closer to 5 pounds after running a couple of thousand rounds through it.

This tracks as Glock lists their standard for the trigger as 26 Newtons, which converts to about 5.84 pounds. With a rounded trigger bow, after about a half-inch travel you hit the wall and pull through for another quarter inch until it breaks. Reset is audible and tactile after about a third of an inch. Unlike some inexpensive competitors in the striker-fired game (Taurus G2/G3), there is no second-strike ability.

Also, the center blade safety lever is very noticeable.

While not the best factory trigger in the world when it comes to striker-fired guns– that probably goes to the flat-faced trigger packs on Sig Sauer’s better P320 X models– the Glock 19X is still very workable and houses no spooky surprises.

For those who want, as it uses a standard Gen 5 pack, you can pick up a trigger enhancement kit from companies like Timney, Apex, or a Ghost Trigger to dial the pull, break, and reset in to something more desirable with the swap of the trigger assembly.

Accuracy results

Glock’s new Marksman barrel is probably the best upgrade the company has ever delivered to their standard factory pistols. After using and abusing older Gen 2, Gen 3, and Gen 4 models over the years, the increased practical accuracy observed with Glock’s Gen 5 guns using the GMB is marked.

The GMB, at least according to Glock, uses an improved barrel crown and an enhanced polygonal rifling, which may explain the reason for tighter groups and an overall more accurate gun.

All I know is that I felt like I was a on a carnival shooting game whenever I hit the range with it. Its exceptional accuracy was punching out neat holes in the target center to the point that the gun was almost boring to shoot.

As far as reliability, I suffered no stoppages, jams, or malfunctions that I could blame on the gun. That is not to say I didn’t have a few ammo-related failures as I ran some moody remanufactured loads mixed in with factory brass and steel case rounds and in bullet sizes ranging from 115 through 147 grains in weight.

The brass and steel were fine, but we’d recommend against Uncle Willy’s reloads.

Range Report

My range time wth the Glock 19X and its coyote polymer frame consisted of three extended sessions, each with 600-700 rounds on the menu, firing at a mixture of paper targets and steel plates at distances from 3 yards to 50 yards in five shot groups before letting loose and blasting paper to shreds.

I found the most repeatable accuracy with Federal’s Syntech target loads, Winchester’s 124-grain NATO, and PMC Bronze 115 when it came to training fodder while Speer’s 124-grain Gold Dot and Federal’s 147-grain HST were laser-accurate when stacking up the assorted personal protection loads.

For more than 2,000 rounds, the G19X proved itself over and over and never supplied one of those “hey, look at this” moments, which is about as much as you can ask of a firearm.

Training Ammunition Performance

Self-Defense Ammunition Performance

Field stripping for cleaning and maintenance is much the same as with any Glock.

With an empty and unloaded pistol, drop the mag and verify the chamber is clear then hold the slide back about a quarter of an inch, pull down the dual take-down levers on each side of the frame, release the slide, pull the trigger (see why you want to make sure you do this on an unloaded and empty pistol!?) to release the tension on the striker and push the slide off the frame.

I did an inspection and take down before my first range trip coupled with cleaning after finishing with each session, making sure to leave only a fine line of lube (Ballistol but your own choice may vary) on metal-to-metal moving surfaces. Maintenance was easy and accomplished in minutes and, between the nPVD slide coating and nDLC barrel finish, the pistol held up very well.

It isn’t hard to keep a high-mileage Gen 5 Glock rolling when it comes to extended use, changing the recoil spring assembly every 7,500 rounds or so and the other springs (striker spring, striker safety spring, extractor depressor spring, mag catch spring, trigger spring, slide lock spring, and slide stop lever spring) every 15-20,000 rounds or so.

The Glock 19X came about as part of a military pistol competition with roots in the circa 2014 period, and it shows. While reliable and dependable– a true combat pistol if you will– it is not optics ready and the slide will need to be milled by a professional to fit a micro red dot, now about the most popular accessory for a handgun other than a holster.

A bit of a confusing design, it has most of the features of Glock’s Gen5 models but not all, a child of the company’s transitional period between generations. Further, the “toe” of the extended magwell and plastic lanyard ring stand out like a sore thumb when viewed through the lens of most consumers.

The long G17-sized grip can be difficult to conceal, especially for those with slim frames seeking to carry AIWB under a graphic tee.

Now pushing a decade old, the G19X is beginning to feel dated, especially when compared to other, more modern, Glock models and the new breed of “micro 9s” like the Sig Sauer P365 and Springfield Amory Hellcat that have been introduced in the past few years.

The 19X faces its strongest competition from within Glock’s own lineup, particularly the G45 series that refined the crossover concept with modern features.

Glock took the G19X and developed it into their first standalone Gen5 pistol series, the G45. Introduced in late 2018– just months after the 19X was announced– the G45 uses the same “Crossover” concept blending the Model 17-sized grip and Model 19-sized slide.

More than just a G19X semi auto pistol in black and with forward slide serrations, the G45 is available in a Modular Optic System, or MOS, variant that allows quick mounting of red dots.

It also deletes the troublesome toe on the magwell and the GI lanyard ring in addition to a few other small tweaks to the design. In other words, if you like the G19X, odds are, you’ll love its half-brother, the G45.

It is little wonder that, while the G19X tanked when it came to scoringå big contracts, the follow-on G45 MOS has become Glock’s best-selling law enforcement handgun model in recent years.

For those looking for something more concealable for EDC/concealed carry use, the G43X MOS, fitted with Shield Arms’s innovative S15 magazines, may be perfect.

Glock 45 vs. Glock 19X Comparison

The Glock 45 MOS offers the best overall value with modern features and optics readiness. Choose the 19X only if you specifically want the Coyote Tan finish or historical significance.

Non-Glock Alternatives

Primary Competitors

SIG Sauer P320 Series

The P320 Carry offers similar crossover dimensions with a 3.9-inch barrel and full-size grip, but in a truly modular platform. The X-Carry variant includes optics readiness and an enhanced flat trigger that many shooters prefer over Glock’s curved design.

Both SIG models provide excellent out-of-box triggers and more refined ergonomics, though they lack Glock’s extensive aftermarket support.

Smith & Wesson M&P 2.0

The M&P 2.0 in 4-inch configuration provides comparable capacity and dimensions at a lower price point. The aggressive grip texturing offers excellent control, and the hinged trigger design appeals to many shooters. However, the trigger feel isn’t as refined as the 19X, and the pistol lacks the proven track record of Glock reliability.

So, how does the Glock 19X stack up on our 10-point score?

Accuracy: 8/10

The addition of the Marksman barrel gives the G19X impressive mechanical accuracy.

Ergonomics: 6/10

It’s Block, so the G19X isn’t trying to change the world when it comes to ergonomics. That said, the full-size grip gives you more control than similar-sized Glocks.

Features: 4/10

In short the Glock 19X lacks certain features most shooters want — like optics support and front slide serrations that are available on newer models.

Fit and Finish: 8/10

Glock has a reputation for building quality firearms, and the Glock 19X is no exception. More than 2,000 rounds in and I’ve yet to replace a thing on my G19X.

Reliability: 10/10

The G19X was built for the MHS competition, so it’s going to be (and has proven in my experience) exceptionally reliable.

Value: 4/10

Does the Glock 19X offer a good value relative to other Glocks? Not so much. The lack of certain features and dated design means you can likely get more from newer products, often for less.

Introduced in 1986, the original Glock 19 was a slightly down-sized variant of Mr. Gaston Glock’s 9mm Pistole 80/G17 service/sport pistol, the latter a polymer-framed striker-fired game changer with a 17+1 standard capacity magazine.

When it came to the bottom line, the Glock tested slightly better with warfighters who evaluated it– earning a “good” rating against Sig’s “acceptable” rating, but the latter company blew Glock out of the water in terms of cost with Sig saying they could deliver 550,000 guns for $169.5 million against Glock’s bid of $272.2 million.

This, as the GAO would contend in a later unsuccessful challenge to the award by Glock, made the Sig P320 variants the better value to the taxpayer. Sig went on to win the competition and then fielded as the M17 and M18 pistols to the entire Department of Defense.

However, as each competitor had sunk lots of R&D dollars and hours into chasing the Army’s new standard, 2017 went on to see the introduction of several new pistols based on their MHS program submissions. This included the FN 509, the S&W M&P M2.0, the Ruger American pistol, and the Beretta APX. Glock’s MHS design would be fleshed out and hit the commercial market at SHOT Show 2018 as the G19X.

A hybrid between Glock’s two most popular 9mm handgun models that was developed with the U.S. Army in mind and left without a home, the Glock 19X has a curious backstory in the “what could have been” category when dropped onto the civilian market.

However, moving past the MHS nostalgia, this Glock pistol is almost amazingly accurate, rock-solid dependable, and versatile in addition to just flat-out looking good to those who dig flat dark earth (err, “coyote finish” Glock guns.

Handy for range visits, competition, or protection, it is also able to draw from the vast supply of standard Glock-pattern parts and mags for support. I bet that, while its military service was short-lived, the Glock 19X will keep on serving for generations to come. It’s a great gun that has more than enough capability for any prospective user.
