How long is a 9mm pistol? The most popular 9mm pistols are 5.8 to 8.5 inches long (147 to 217 mm) overall, with barrels of 3 to 4.9 inches (76 to 125 mm) and weights of 17.8 to 33.3 ounces (500 to 945 g). The shortest is the SIG Sauer P365 at 5.8 inches, and the longest is the Beretta 92FS at 8.5 inches — a difference of 2.7 inches between the smallest and the largest.
There is no single “9mm pistol” size, because 9mm is a cartridge, not a gun. The 9x19mm Parabellum round is chambered in dozens of pistols, from pocket-size micro-compacts to full-size duty guns. They all fire the same 9.01 mm (0.355-inch) bullet, but the pistols range from barely longer than a smartphone to longer than a house brick. This guide compares the seven most popular 9mm pistols side by side.

Quick tip: *Weights are with an empty magazine unless noted. The P365’s 17.8 oz is SIG Sauer’s listed weight, and the Shield Plus is 17.9 oz (508 g) without a magazine and 20.2 oz (573 g) with its empty 10-round magazine. Generations and finishes can shift any figure slightly, so check the manufacturer’s spec sheet for the exact model.
9mm Pistol Sizes Compared, Model by Model
SIG Sauer P365 — 5.8 Inches
The SIG Sauer P365 is the smallest pistol here at 5.8 inches (147 mm) long, with a 3.1-inch (78 mm) barrel. It is 4.3 inches (109 mm) tall and 1.0 inch (26 mm) wide, and it weighs 17.8 ounces (500 g). It holds 10+1 rounds in its flush magazine. Built for deep concealment, it is 1.48 inches shorter than a Glock 19 and 2.7 inches shorter than a Beretta 92FS.
Springfield Hellcat — 6.0 Inches
The Springfield Hellcat is 6.0 inches (152 mm) long with a 3.0-inch (76 mm) barrel, the shortest barrel here. It is 4.0 inches (102 mm) tall with a flush magazine and 1.0 inch (25 mm) wide at the grip, and it weighs 17.9 ounces (508 g) with the flush 11-round magazine, or 18.3 ounces (519 g) with the extended 13-round magazine. It is only 0.2 inches longer than the P365, but its grip is 0.3 inches shorter, so it hides under a shirt even more easily.
Smith & Wesson M&P Shield Plus — 6.1 Inches
The Smith & Wesson M&P Shield Plus is 6.1 inches (155 mm) long with a 3.1-inch (79 mm) barrel. It is 4.6 inches (117 mm) tall and 1.1 inches (28 mm) wide, and it weighs 20.2 ounces (573 g) with its empty 10-round magazine. It holds 13+1 rounds with the extended magazine, the most capacity of any micro-compact here. At 6.1 inches, it is almost exactly the length of a US dollar bill.
Glock 19 (Gen5) — 7.28 Inches
The Glock 19 Gen5 is 7.28 inches (185 mm) long with a 4.02-inch (102 mm) barrel. It is 5.04 inches (128 mm) tall and 1.34 inches (34 mm) wide, and it weighs 23.63 ounces (670 g) with an empty magazine, or 21.34 ounces (605 g) without one. It holds 15+1 rounds. It is the compact middle of the range: 1.18 to 1.48 inches longer than the micro-compacts and 0.67 inches shorter than the Glock 17. The older Gen3 is slightly different at 7.36 inches (187 mm) long and 1.26 inches (32 mm) wide.
CZ P-10 C — 7.3 Inches
The CZ P-10 C is 7.3 inches (187 mm) long with a 4.02-inch (102 mm) barrel, almost exactly the same footprint as a Glock 19. It is 5.2 inches (132 mm) tall and 1.26 inches (32 mm) wide, and it weighs 26 ounces (740 g) with an empty magazine. It holds 15+1 rounds. It is the heaviest compact here at 26 ounces, 2.37 ounces more than a Glock 19. CZ’s own metric sheet lists the length as 187 mm and the height as 135 mm, which is why some sources round the height to 5.3 inches.
Glock 17 (Gen5) — 7.95 Inches
The Glock 17 Gen5 is 7.95 inches (202 mm) long with a 4.49-inch (114 mm) barrel. It is 5.47 inches (139 mm) tall and 1.34 inches (34 mm) wide, and it weighs 24.97 ounces (708 g) with an empty magazine, or 22.22 ounces (630 g) without one. It holds 17+1 rounds. Compared with the Glock 19, it is 0.67 inches longer, its barrel is 0.47 inches longer, its grip is 0.43 inches taller, and it is 1.34 ounces heavier. The older Gen3 is slightly longer still at 8.03 inches (204 mm).
Beretta 92FS — 8.5 Inches
The Beretta 92FS is the largest pistol here at 8.5 inches (217 mm) long with a 4.9-inch (125 mm) barrel. It is 5.4 inches (137 mm) tall and 1.5 inches (38 mm) wide, and it weighs 33.3 ounces (945 g) unloaded. It holds 15+1 rounds. It is 2.7 inches longer than a P365 and 0.55 inches longer than a Glock 17, and at 33.3 ounces it is 15.5 ounces heavier than a P365 — nearly twice the weight. It is an all-metal, double/single-action pistol with an open slide, a design that served as the US military sidearm for decades.
9mm Barrel Lengths: 3 Inches to 4.9 Inches
Barrel length is the main reason these pistols differ in overall length. The barrels in this comparison run from 3.0 inches to 4.9 inches, a spread of 1.9 inches.
- 3.0-inch barrel: Springfield Hellcat, the shortest barrel here. A 3.0-inch barrel is 76.2 mm long.
- 3.1-inch barrel: SIG Sauer P365 and Smith & Wesson M&P Shield Plus. A 3.1-inch barrel is 78.7 mm long.
- 4.02-inch barrel: Glock 19 and CZ P-10 C. A 4.02-inch barrel is 102.1 mm long.
- 4.49-inch barrel: Glock 17. A 4.49-inch barrel is 114 mm long.
- 4.9-inch barrel: Beretta 92FS, the longest barrel here. A 4.9-inch barrel is 124.5 mm long.
A longer barrel gives the bullet a little more speed and a longer sight radius, which helps accuracy. A typical 115-grain 9mm round leaves a 4-inch barrel at about 1,150 feet per second, and a 3-inch barrel costs roughly 50 to 100 feet per second. That is why micro-compacts give up a little velocity for their short size, and why full-size pistols are the choice when performance matters more than concealment.
How Much Does a 9mm Pistol Weigh?
A 9mm pistol weighs 17.8 to 33.3 ounces (500 to 945 g) with an empty magazine, a range of 15.5 ounces, or almost a full pound. The two lightest are the polymer-framed micro-compacts, the SIG P365 at 17.8 ounces (500 g) and the Springfield Hellcat at 17.9 ounces (508 g). The Shield Plus is next at 20.2 ounces (573 g), then the Glock 19 at 23.63 ounces (670 g) and the Glock 17 at 24.97 ounces (708 g). The CZ P-10 C is heavier than both Glocks at 26 ounces (740 g), and the all-metal Beretta 92FS is the heaviest by a wide margin at 33.3 ounces (945 g), or 2.08 pounds.
A loaded magazine adds roughly 5 to 7 ounces, so a ready-to-carry Glock 19 is about 29 to 31 ounces (about 1.9 pounds), while a loaded Beretta 92FS is about 38 to 40 ounces (about 2.4 pounds). That half-pound difference is easy to feel after a full day on the hip.
How Big Is the 9mm Cartridge?
Every pistol in this guide fires the same cartridge: the 9x19mm Parabellum, also called 9mm Luger or 9mm NATO. It was designed by Georg Luger and introduced in 1902, and it is now the standard pistol cartridge for NATO forces and the most popular handgun caliber in the United States.
- 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
The cartridge is small: at 1.169 inches long it is only about one-third as long as a credit card. That is why a pistol like the P365 can hold 10 rounds in a grip just 4.3 inches tall, and why the 9mm became the default carry caliber. The “9mm” is the bullet diameter (9.01 mm) and the “19mm” is the case length (19.15 mm).
What the Size Differences Mean in Practice
Concealed Carry: The Micro-Compacts
For concealed carry, the smallest pistols win. The P365 (5.8 in), Hellcat (6.0 in) and Shield Plus (6.1 in) are all under 6.1 inches long, under 4.6 inches tall and about 1 inch wide, weighing 17.8 to 20.2 ounces. That size hides under a normal shirt and stays comfortable all day. The Hellcat’s 4.0-inch height is the shortest grip here, and the grip is the part that prints through clothing, so it matters most for hiding a pistol.
Duty and Home Defense: The Full-Size Pistols
For duty, home defense and range use, the full-size pistols win. The Glock 17 (7.95 in), Beretta 92FS (8.5 in) and CZ P-10 C (7.3 in) have longer barrels, longer grips and higher capacities, which means less felt recoil, a longer sight radius and more rounds before a reload. The 92FS is the biggest and heaviest, and its 33.3-ounce all-metal frame soaks up recoil better than any polymer pistol here. A full-size pistol is harder to hide, but at home or on a duty belt that does not matter.
The Compromise: The Glock 19
The Glock 19 (7.28 in) is the compromise that sells the most: 0.67 inches shorter than a Glock 17 and 1.48 inches longer than a P365, with a 15-round magazine that splits the difference. It is small enough to carry concealed with the right holster and large enough to shoot comfortably at the range. The CZ P-10 C fills the same role at almost exactly the same size, 7.3 inches long, but it is 2.37 ounces heavier.
Everyday Size Comparisons: How Long Is a 9mm Pistol Really?
A number like 7.28 inches is hard to picture on its own. Here is how these pistols compare with things you already know.
US Dollar Bill
A US dollar bill is 6.14 inches long (15.6 cm). The Springfield Hellcat, at 6.0 inches, is 0.14 inches shorter than a dollar bill, and the Smith & Wesson Shield Plus, at 6.1 inches, is 0.04 inches shorter — essentially the same length. The SIG P365, at 5.8 inches, is 0.34 inches shorter than a dollar bill. The Glock 19 is 1.14 inches longer than a dollar bill, and the Beretta 92FS is 2.36 inches longer.
iPhone 16
A standard iPhone 16 is 5.81 inches tall (147.6 mm). The SIG Sauer P365, at 5.8 inches long, is essentially the same length as an iPhone 16 standing upright — only 0.01 inches shorter. The Hellcat is 0.19 inches longer than the phone, and the Shield Plus is 0.29 inches longer.
Credit Card
A standard credit card is 3.375 inches long (85.6 mm). The Hellcat’s 3.0-inch barrel is 0.375 inches shorter than a credit card’s long edge, and the P365 and Shield Plus barrels, at 3.1 inches, are 0.275 inches shorter. Even the Glock 17’s 4.49-inch barrel is only 1.115 inches longer. The whole 9mm cartridge, at 1.169 inches, is about one-third of a credit card’s length.
Soda Can
A standard 12-ounce soda can is 4.83 inches tall (12.27 cm) and 2.6 inches across. The Glock 19’s height of 5.04 inches is 0.21 inches taller than a soda can, and the Glock 17 at 5.47 inches is 0.64 inches taller. The P365, at 4.3 inches tall, is 0.53 inches shorter, and the Hellcat, at 4.0 inches, is 0.83 inches shorter.
House Brick
A standard US house brick is nominally 8 inches long (20.32 cm). The Beretta 92FS, at 8.5 inches, is 0.5 inches longer than a brick. The Glock 17, at 7.95 inches, is 0.05 inches shorter — essentially brick-length. The Glock 19 is 0.72 inches shorter than a brick, and the P365 is 2.2 inches shorter.
Tennis Ball
A standard tennis ball is 2.57 to 2.70 inches across (6.54 to 6.86 cm). The Beretta 92FS, at 1.5 inches wide, is just over half a tennis ball wide. The P365 and Hellcat, at 1.0 inch wide, are about 37 percent of a tennis ball’s diameter, and the Glocks, at 1.34 inches wide, are about half. The 9mm bullet itself, at 0.355 inches across, is slightly wider than a standard pencil, about 0.28 inches across.
