When it comes to choosing the right handgun, Glock has established itself as a top choice for law enforcement, military and civilian use. Two of its most popular models, the Glock 19 and the Glock 17, often leave potential buyers wondering which is the better fit for  their needs.

In this blog post, we’ll explore the functional differences between these two models, their ammunition, customization options and the scenarios in which one might be preferred over the other. As firearms experts at AimHi Family Firearms Center, we’re here to share with you with you the information you need to make an informed decision and able to help guide you through your next firearm purchase.

Functional Differences

The Glock 19 and Glock 17 are both 9mm handguns, but they have distinct characteristics that set them apart.

Size & Weight

Glock 19

  • Glock 19: The Glock 19 is a compact model, with an overall length of 7.36 inches and a barrel length of 4.02 inches. It stands at 5.04 inches tall and weighs approximately 23.65 ounces when unloaded. Its compact size makes it an excellent choice for concealed carry and shooters with smaller hands.

The larger size provides a longer sight radius — the span between front and rear sights — which can improve accuracy at long distances.

Magazine Capacity

  • Glock 19: Standard magazine capacity is 15 rounds, with options for extended magazines.
  • Glock 17: Standard magazine capacity is 17 rounds, also with options for extended magazines.

Grip

  • Glock 19: Slightly shorter grip, which may be more comfortable for shooters with smaller hands or those looking for a more concealable firearm.
  • Glock 17: Longer grip, providing a more comfortable hold for people with larger hands and potentially more stability when firing.

Ammunition Differences

9mm Luger Ammo

Both the Glock 19 and Glock 17 use the same 9mm Luger ammunition, which is known for its power, recoil and affordability. The differences in magazine capacity mean the Glock 17 can hold two more rounds than the Glock 19, but this difference is usually not a concern in most situations. Both models can use a variety of 9mm types, including full metal jacket for practice and hollow points for self-defense.

Scenarios for Each Handgun

Glock 19

  • Concealed Carry: The compact size of the Glock 19 makes it ideal for concealed carry, fitting comfortably in holsters and being easier to conceal under clothing.
  • Everyday Carry: Its lighter weight and smaller size make it a convenient option for daily carry without sacrificing much in terms of firepower.
  • Home Defense: The Glock 19 is versatile enough to used effectively in home defense scenarios, providing sufficient capacity and stopping power.

Glock 17

  • Duty Use: The Glock 17’s larger size and greater magazine capacity make it a go-to choice for law enforcement and military personnel.
  • Range Shooting: The longer barrel and sight radius enhance accuracy, making it a favorite among target shooters and competitors.
  • Home Defense: Its larger size can provide a more stable shooting experience in high-stress situations, and the extra rounds can be helpful.

Customization Options

Both the Glock 19 and Glock 17 are highly customizable, allowing shooters to tailor their firearms to their distinct needs:

  • Sights: Both models can be fitted with a variety of sights, including night sights, fiber optic sights and red dot sights.
  • Triggers: Custom trigger options can improve the feel and reduce the pull weight for better accuracy.
