For firearms enthusiasts and Glock fans, a common question is how the Glock 47 compares to the popular and well-known Glock 17 model.

If you’re short on time, here’s a quick answer: The Glock 47 and Glock 17 are both full-size, 9mm semi-automatic pistols. They are very similar in design and function, but there are a few key differences.

The Glock 17 offers a bit more durability and parts availability due to its longer history and wider use.

Glock 17 Overview and Background

The Glock 17 is a popular semi-automatic pistol that has gained a reputation for its reliability, durability, and performance.

It is one of the most widely used handguns by military, law enforcement, and civilian shooters alike.

Let’s take a closer look at the history, size, dimensions, basic specs, and standard features of the Glock 17.

Glock 17

History and Development

The Glock 17 was first introduced in 1982 by the Austrian firearms manufacturer Glock Ges.m.b.H. It was designed by Gaston Glock, an engineer with no prior experience in firearms.

The Glock 17 was Glock’s first pistol, and it revolutionized the industry with its innovative design and use of polymer materials.

Glock’s goal was to create a handgun that was lightweight, reliable, and easy to maintain.

The Glock 17 was the result of his efforts, and it quickly gained popularity among shooters worldwide. Its success paved the way for the development of other Glock models.

Size, Dimensions, and Basic Specs

The Glock 17 is a full-size handgun with a standard magazine capacity of 17 rounds.

It has a barrel length of 4.49 inches and an overall length of 7.95 inches. The pistol weighs approximately 24.69 ounces without the magazine.

One of the standout features of the Glock 17 is its dual recoil spring assembly, which helps reduce felt recoil and improve overall shooting performance. It also features a striker-fired mechanism, which provides a consistent trigger pull each time.

Standard Features and Configurations

The Glock 17 comes with a number of standard features that contribute to its popularity.

It has a polymer frame, which makes it lightweight and resistant to corrosion. The frame also has interchangeable backstraps, allowing shooters to customize the grip to their preference.

Another notable feature of the Glock 17 is its Safe Action System, which consists of three automatic safeties: trigger safety, firing pin safety, and drop safety.

These safeties help prevent accidental discharges and make the Glock 17 a safe choice for everyday carry.

The Glock 17 is available in different configurations, including variations with night sights, threaded barrels for suppressor use, and MOS (Modular Optic System) versions that allow for the easy mounting of red dot sights.

Development History and Release

The Glock 47 was first unveiled at SHOT Show 2022 as part of Glock’s “Gen5 MOS” series. It represents Glock’s first efforts in the popular PCC (pistol caliber carbine) market.

The G47 launched in early 2022 as a 9mm carbine built off the proven Glock 17 pistol platform, offering familiar ergonomics and reliability.

It caters to both law enforcement and civilian shooters looking for an affordable, U.S.-made PCC.

Size, Dimensions, and Specs

The G47 measures 7.95 inches long with a 4.49-inch barrel length. It weighs just 23.93 ounces unloaded.

The nylon polymer frame, Picatinny top rail, ambidextrous controls, and flared mag well carry over from the pistol models.

It uses the same 17-round standard magazines as the G17 for interchangeability. The serialized trigger mechanism housing also transfers between the G47 and G17.

Standard Features and shootability

With adjustable sights, a reversible charging handle and magazine release, and a MOS cut slide, the G47 comes well-equipped out of the box.

It shoots smoothly and controllably thanks to the proven Glock action and light recoiling 9mm cartridge.

Reliability is excellent with a wide variety of ammunition. The G47 brings versatile home defense and plinking abilities in a compact PCC package.

Direct Comparison of Size and Dimensions

Differences in dust cover on the slide and the recoil system

The Glock 47 and Glock 17 have the same slide width and grip of about 1.34 inches. This is because the Glock 47 and Glock 17 share the same frame.

The only difference between the two pistols is the dust cover on the slide and the recoil system. 

The dust cover is the part of the slide that covers the recoil spring.

The dust cover on the Glock 47 is slightly shorter than the dust cover on the Glock 17. This is what makes the Glock 47 slightly shorter overall and lighter.

The recoil system is the spring and guide rod assembly that absorbs the recoil of the pistol when it is fired.

The recoil system on the Glock 47 is the same as the recoil system on the Glock 19, while the recoil system on the Glock 17 is slightly different.

Despite the differences in the dust cover and recoil system, the Glock 47 and Glock 17 have the same slide width and grip. This means that holsters and other accessories that are designed for the Glock 17 will also fit the Glock 47.

Weight Comparison When Loaded

Weight is an important factor to consider when comparing these two firearms.

The Glock 47 and Glock 17 have the same magazine capacity of 17 rounds. However, the Glock 47 is slightly lighter than the Glock 17, even when loaded.

The Glock 47 weighs 23.93 ounces when empty and 34.29 ounces when loaded. On the other hand, the Glock 17 weighs 24.69 ounces when empty and 35.03 ounces when loaded.

The difference in weight is due to the shorter dust cover on the Glock 47. The shorter dust cover on the Glock 47 saves a few ounces in weight.

In addition, the Glock 47 uses the same recoil spring as the Glock 19, while the Glock 17 uses a longer recoil spring. The longer recoil spring on the Glock 17 is slightly heavier.

However, it’s essential to note that the weight difference is not significant enough to impact the overall handling and performance of the firearm.

Both the Glock 47 and Glock 17 are known for their lightweight construction, which contributes to their popularity among shooters.

Detailed Dimension Measurements

Both the Glock 47 and Glock 17 have the same dimensions in terms of barrel length, overall length, height, and width. 

Both firearms have the following key specifications:

  • Barrel length: 4.49 inches
  • Overall length: 7.95 inches
  • Height: 5.47 inches
  • Width: 1.34 inches

As you can see, the Glock 47 and Glock 17 have the same dimensions in terms of barrel length, overall length, height, and width.

The only difference is in weight, with the Glock 47 being slightly lighter. This is due to the shorter dust cover on the Glock 47.

Please note that these dimensions are for the Glock 47 and Glock 17 with standard magazines. If you are using a magazine with a higher capacity, the overall length and height of the pistol may be slightly greater.

Shooting Performance and Feel
