How long is a Glock 19 Gen 6? The Glock 19 Gen 6 is 7.28 inches long (18.49 cm) overall, with a 4.02-inch barrel (10.21 cm). It is 5.04 inches tall (12.80 cm) with a magazine fitted and 1.35 inches wide (3.43 cm) at its widest point. Unloaded, it weighs 20.11 ounces (570 g) without a magazine and 22.58 ounces (640 g) with an empty magazine.
The Gen 6 is Glock’s newest generation of pistols. Glock announced the Gen 6 line on December 6, 2025, and the Glock 19 Gen 6 reached store shelves on January 20, 2026, launching alongside the full-size Glock 17 Gen 6 and the crossover Glock 45 Gen 6. All three are 9mm pistols. The Gen 6 did not change the Glock 19’s size: the barrel, the overall length and the height are exactly the same as the Gen 5. What changed is everything around those numbers — a flat-faced trigger, a factory optic-ready slide, and a reworked grip with a palm swell, an extended thumb rest and an enlarged beavertail.
Glock 19 Gen 6 Length at a Glance
| Measurement | Inches | Centimeters | Millimeters |
|---|---|---|---|
| Barrel length | 4.02 in | 10.21 cm | 102 mm |
| Overall length | 7.28 in | 18.49 cm | 185 mm |
| Slide length | 6.85 in | 17.40 cm | 174 mm |
| Height with magazine | 5.04 in | 12.80 cm | 128 mm |
| Overall width | 1.35 in | 3.43 cm | 34.4 mm |
| Slide width | 1.00 in | 2.54 cm | 25.5 mm |
| Sight radius (polymer sights) | 6.18 in | 15.70 cm | 157 mm |
| Trigger distance | 2.68 in | 6.81 cm | 68 mm |
| Cartridge overall length (9mm) | 1.169 in | 2.97 cm | 29.69 mm |
| Cartridge case length (9mm) | 0.754 in | 1.92 cm | 19.15 mm |

Quick tip: Glock publishes two widths for this pistol, and they measure different things. The 1.35-inch overall width is measured across the slide stop lever, the widest external control. The 1.00-inch slide width is the number that matters for concealment, because the slide is the part that actually has to disappear under clothing.
How Long Is a Glock 19 Gen 6 with a 4.02-Inch Barrel?
A Glock 19 Gen 6 with its standard 4.02-inch barrel is 7.28 inches long overall (18.49 cm, or 0.61 feet). The barrel itself is 10.21 centimeters (102 mm) long, or 0.34 feet.
The overall length is longer than the barrel by 3.26 inches, because the slide and frame extend past the muzzle. The slide alone is 6.85 inches long (17.40 cm).
The sight radius is 6.18 inches (15.70 cm) with the standard polymer sights — 2.16 inches longer than the barrel — dropping to 6.14 inches (15.60 cm) with steel sights and 6.10 inches (15.49 cm) with night sights.
Glock 19 Gen 6 Barrel: 4.02 Inches of Glock Marksman Barrel
The Glock 19 Gen 6 uses a 4.02-inch Glock Marksman Barrel (GMB), the same barrel length Glock has used on the compact Glock 19 since the beginning. The barrel is cold hammer forged with Glock’s Tenifer surface treatment. At 4.02 inches, it sits in the middle of the Glock 9mm range: longer than the 3.43-inch barrel of the subcompact Glock 26, and shorter than the 4.49-inch barrel of the full-size Glock 17 Gen 6.
One change matters more than the length. Glock revised the barrel geometry for the Gen 6, so Gen 5 barrels do not fit in a Gen 6 pistol. Your magazines carry over, most holsters carry over and most sights carry over, but your barrels do not — including aftermarket match and threaded barrels bought for a Gen 5. Glock also did not offer a factory threaded barrel at launch, though it has confirmed one is coming.
How Much Does a Glock 19 Gen 6 Weigh?
A Glock 19 Gen 6 weighs 20.11 ounces (570 g) without a magazine, 22.58 ounces (640 g) with an empty magazine fitted, and 29.10 ounces (825 g) with a loaded 15-round magazine — 1.26, 1.41 and 1.82 pounds respectively.
Two weights cause confusion, so here is the honest explanation. Some retailers list the Glock 19 Gen 6 at 22.58 ounces and call it “the weight,” while others list 20.11 ounces. Both numbers are Glock’s own figures — they just count different things. The 20.11-ounce figure is the bare pistol with no magazine at all. The 22.58-ounce figure adds the empty 15-round magazine, which weighs 2.47 ounces (70 g) on its own. When you compare pistols, always check whether the magazine is included.
Fifteen rounds of 9mm add about 6.5 ounces over the empty gun, roughly a third of the pistol’s bare weight. That is worth holding in your head if you carry: the loaded pistol at 29.10 ounces is noticeably heavier on the belt than the 20.11-ounce figure on the spec sheet suggests.
Against the Gen 5, the Gen 6 is about an ounce lighter: the Gen 5 is commonly published at about 23.6 ounces (670 g) with an empty magazine, against the Gen 6’s 22.58 ounces (640 g) — a difference you will not feel in the hand.
How Big Is the 9mm Cartridge?
The Glock 19 Gen 6 fires the 9x19mm Parabellum cartridge, the most common pistol cartridge in the world, also called 9mm Luger. The cartridge is short and straight-walled, which is why 15 of them fit in a magazine that still leaves the pistol only 5.04 inches tall.
- Bullet diameter: 0.355 inches (9.01 mm)
- Case length: 0.754 inches (19.15 mm)
- Overall cartridge length: 1.169 inches (29.69 mm)
- Maximum pressure (SAAMI): 35,000 psi
- Common bullet weights: 115, 124 and 147 grains (a 124-grain bullet is the most common duty and practice load)
The whole pistol is about six cartridges long: 7.28 inches divided by the cartridge’s 1.169-inch overall length is 6.23, so six 9mm cartridges laid end to end are 7.01 inches, just 0.27 inches short of the pistol’s full length.
Glock 19 Gen 6 vs Gen 5: Same Size, New Details
The Gen 6 is not a redesign of the Glock 19. It is a refinement. Every core dimension is unchanged from the Gen 5.
| Specification | Glock 19 Gen 5 | Glock 19 Gen 6 |
|---|---|---|
| Caliber | 9x19mm | 9x19mm |
| Barrel length | 4.02 in (102 mm) | 4.02 in (102 mm) |
| Overall length | 7.28 in (185 mm) | 7.28 in (185 mm) |
| Height with magazine | 5.04 in (128 mm) | 5.04 in (128 mm) |
| Width | 1.34 in (34 mm) | 1.35 in (34.4 mm) |
| Weight, empty magazine | About 23.6 oz (670 g) | 22.58 oz (640 g) |
| Capacity | 15+1 | 15+1 |
| Trigger | Curved shoe, 26 N (about 5.8 lb) | Flat-faced, 26 N (about 5.8 lb) |
| Optics | MOS plate system | ORS direct-milled slide |
| Grip texture | Gen 5 RTF | RTF6, palm swell, thumb rest, beavertail |
What actually changed, in order of importance:
- Trigger: the Gen 6 moves to a flat-faced trigger with a shorter pre-travel and a crisper reset. Glock’s published pull weight is the same 26 N (about 5.8 lb) as the Gen 5, but one hands-on test measured an average pull of about 5.5 pounds with a noticeably cleaner break. Individual pistols vary, but the factory figure is 26 N.
- Optics: the Gen 6 ditches the stacked MOS plate arrangement and mounts a red dot directly to the slide. The system is called the Optics Ready System (ORS), and the box ships with three adapter plates covering RMR, DeltaPoint and C-More footprints, so the mount sits lower and does not wobble.
- Grip: the frame gets a refined angle and upper contour, an integrated beavertail, a palm swell and an extended thumb rest, with a new RTF6 grip texture that Glock describes as two patterns combined into one.
- Slide: the serrations are deeper and more aggressive than the Gen 5, and the slide wears Glock’s nDLC finish.
- In the box: three 15-round magazines, a speed loader, a cleaning kit, 2 mm and 4 mm backstraps, three optic adapter plates and a hard case.
What did not change: the caliber, the 15+1 capacity, the barrel length, the overall length, the height, the Safe Action system, and the magazine compatibility — every Gen 3, Gen 4 and Gen 5 double-stack 9mm magazine works in the Gen 6.
The price did change. The Glock 19 Gen 6 lists at $745 MSRP, with street prices from about $620 at major retailers as of 2026. That is higher than a Gen 5 on clearance, and rival pistols with similar features sell for $100 to $200 less — so the Gen 6 is a buy-new decision, not an upgrade decision. If your Gen 5 runs well, you do not need this gun.
Do not confuse the Glock 19V, a separate compliance-driven model still widely stocked, with the Gen 6 — they are different pistols in Glock’s catalog.
Glock 19 Gen 6 vs Glock 17 Gen 6 and Glock 45 Gen 6
Glock launched the Gen 6 with three pistols, all 9mm, all sharing the same trigger, optic system and grip work.
The Glock 17 Gen 6 is the full-size duty pistol: a 4.49-inch barrel (11.40 cm), 7.95 inches long overall (20.19 cm), 5.47 inches tall (13.89 cm) and 17+1 capacity. It is 0.67 inches longer than the Glock 19 Gen 6, and it weighs 21.16 ounces (600 g) without a magazine and 23.99 ounces (680 g) with an empty one.
The Glock 45 Gen 6 is the crossover: the Glock 17’s full grip with the Glock 19’s shorter slide. It has the same 4.02-inch barrel as the Glock 19 Gen 6, but it is 7.44 inches long overall (18.90 cm) and holds 17+1 rounds. It weighs 20.28 ounces (575 g) without a magazine.
All three take the same magazines, and every Gen 3, Gen 4 and Gen 5 double-stack 9mm magazine you already own works in them.
Everyday Size Comparisons: How Long Is a Glock 19 Gen 6 Really?
A number like 7.28 inches is hard to picture on its own. Here is how the Glock 19 Gen 6 compares with things you already know.
Standard Pencil
A standard unsharpened pencil is 7.5 inches long (19.05 cm). The Glock 19 Gen 6 is 0.22 inches shorter than a pencil — about 97 percent of a pencil’s length, which makes the pencil the closest everyday match for the gun’s overall size.
US Dollar Bill
A US dollar bill is 6.14 inches long (15.6 cm) and 2.61 inches wide. The Glock 19 Gen 6 is 1.14 inches longer than a dollar bill, or about 19 percent longer.
iPhone 16 Pro Max
An iPhone 16 Pro Max is 6.42 inches tall (16.3 cm) and 3.06 inches wide. The Glock 19 Gen 6 is 0.86 inches longer than the tallest iPhone. The pistol is also 1.35 inches wide against the phone’s 3.06 inches, so it is less than half as wide as the phone — but at 5.04 inches tall, it is only 1.38 inches shorter than the phone is tall.
Soda Can
A standard soda can is 4.83 inches tall (12.27 cm) and 2.6 inches across. The Glock 19 Gen 6 is 2.45 inches longer than a soda can is tall, and its height of 5.04 inches is 0.21 inches taller than the can.
Credit Card
A standard credit card is 3.375 inches long (8.56 cm) and 2.125 inches wide. The Glock 19 Gen 6 is a little more than two credit cards long end to end: two cards measure 6.75 inches, and the pistol adds another 0.53 inches on top of that. The barrel, at 4.02 inches, is about two-thirds of an inch longer than a single credit card.
9mm Cartridge
A 9mm cartridge is 1.169 inches long overall (29.69 mm). The Glock 19 Gen 6 is about six cartridges long: six cartridges laid end to end measure 7.01 inches, just 0.27 inches short of the pistol’s 7.28-inch overall length. The barrel is about three and a half cartridges long, and the pistol’s 1.35-inch width is only 0.18 inches wider than a single cartridge is long.
Frequently Asked Questions
How long is a Glock 19 Gen 6?
A Glock 19 Gen 6 is 7.28 inches long overall (18.49 cm), with a 4.02-inch barrel (10.21 cm), a height of 5.04 inches (12.80 cm) with a magazine, and a width of 1.35 inches (3.43 cm). It weighs 20.11 ounces (570 g) without a magazine and 22.58 ounces (640 g) with an empty magazine, and holds 15+1 rounds.
Is the Glock 19 Gen 6 the same size as the Gen 5?
Yes. The Gen 6 keeps the same barrel length (4.02 inches), overall length (7.28 inches), height (5.04 inches) and 15+1 capacity as the Gen 5. The width grows by 0.01 inches and the weight drops by about an ounce with an empty magazine, but neither difference is noticeable in the hand or the holster.
What is new in the Glock 19 Gen 6?
Three things. First, a flat-faced trigger with a shorter pre-travel and cleaner reset, at the same published 26 N (about 5.8 lb) pull weight. Second, the Optics Ready System (ORS), which mounts a red dot directly to the slide instead of on a stacked MOS plate, with three adapter plates in the box. Third, a reworked grip with RTF6 texture, a palm swell, an extended thumb rest and an enlarged beavertail, plus deeper slide serrations. The barrel geometry also changed, so Gen 5 barrels do not fit the Gen 6.
Conclusion
A Glock 19 Gen 6 is 7.28 inches long (18.49 cm) with a 4.02-inch barrel (10.21 cm), 5.04 inches tall (12.80 cm) and 1.35 inches wide (3.43 cm). It weighs 20.11 ounces (570 g) without a magazine and 22.58 ounces (640 g) with an empty one. That makes it a fraction shorter than a standard pencil, about an inch longer than a dollar bill, and about six 9mm cartridges laid end to end. It is the same size as the Gen 5 in every measurement that matters. The Gen 6 earns its place not by being a different size but by fixing the three things Glock owners complained about most: the trigger, the optic mount and the grip. If you are buying your first Glock 19, this is the one to buy. If your Gen 5 already runs, keep it and spend the money on ammunition.
