What Kind of Ammo Does a Glock 19 Use? A Comprehensive Guide

The Glock 19 is a popular and versatile handgun known for its reliability, accuracy, and manageable size. One of the first questions many new Glock 19 owners ask is: What kind of ammo does a Glock 19 use? The answer is straightforward: The Glock 19 is primarily chambered in 9mm Luger, also known as 9x19mm or 9mm Parabellum. This makes it a readily available and relatively affordable option for target practice, self-defense, and law enforcement. Understanding the nuances of 9mm ammunition and its compatibility with your Glock 19 is crucial for safe and effective use. This article will delve into the specifics of 9mm ammunition, its variations, and other considerations when choosing the right ammo for your Glock 19.

Understanding 9mm Ammunition

The 9mm Luger cartridge is a rimless, tapered cartridge that has become the most popular handgun cartridge in the world. Its widespread adoption is due to its balance of manageable recoil, sufficient stopping power, and high capacity in modern handguns. The ammo is readily available from various manufacturers, making it a cost-effective choice for frequent shooters.

Key Characteristics of 9mm Ammunition

Bullet Weight: 9mm bullets typically range from 115 grains to 147 grains. Lighter bullets (115 grain) generally offer higher velocities and flatter trajectories, while heavier bullets (147 grain) tend to have more recoil and potentially better penetration.
Bullet Type: Common bullet types include Full Metal Jacket (FMJ), Jacketed Hollow Point (JHP), and specialty rounds like frangible or solid copper bullets. FMJ rounds are primarily used for target practice, while JHP rounds are designed for self-defense due to their expansion upon impact, creating a larger wound cavity.
Pressure: 9mm ammunition is generally loaded to standard pressure, but +P (higher pressure) and +P+ (even higher pressure) variants exist. The Glock 19 is designed to handle +P ammunition, but continuous use of +P+ ammunition is not recommended as it can accelerate wear and tear on the firearm.

Choosing the Right 9mm Ammo for Your Glock 19

Selecting the appropriate ammo for your Glock 19 depends on your intended use. Here are some considerations:

Target Practice and Training

For target practice and training, Full Metal Jacket (FMJ) ammunition is the most economical and practical choice. FMJ rounds are typically less expensive than other types of ammo and provide consistent performance for range use. Look for reputable brands like Federal, Winchester, or CCI for reliable performance.

Self-Defense

For self-defense, Jacketed Hollow Point (JHP) ammunition is the preferred choice. JHP rounds are designed to expand upon impact, creating a larger wound cavity and increasing the likelihood of stopping the threat quickly. It’s crucial to select a JHP round that is known for its reliable expansion and penetration. Popular choices include:

Federal HST: Known for its consistent expansion and penetration through various barriers.
Speer Gold Dot: A long-standing favorite among law enforcement and civilians for its reliable performance.
Hornady Critical Defense: Designed for optimal performance in short-barreled handguns and features a polymer insert to prevent clogging of the hollow point.

Always test your chosen self-defense ammo in your Glock 19 to ensure it feeds and cycles reliably. A failure to feed or eject during a critical situation could have dire consequences.

Competition Shooting

For competition shooting, the choice of ammo depends on the specific rules and requirements of the competition. Some competitions may restrict the type of ammunition allowed, while others may allow a wider range of options. Many competitive shooters prefer lighter bullets with a higher velocity for flatter trajectories and faster follow-up shots. Consult the rules of your specific competition and experiment with different types of ammo to find what works best for you.

Other Ammunition Considerations for the Glock 19

While the Glock 19 is primarily designed for 9mm Luger ammunition, there are a few other considerations to keep in mind:

+P and +P+ Ammunition

As mentioned earlier, the Glock 19 is rated to handle +P ammunition. +P ammunition generates higher pressures than standard 9mm rounds, resulting in increased velocity and energy. While the Glock 19 can handle +P ammo, it’s important to note that continuous use of +P ammunition can accelerate wear and tear on the firearm. +P+ ammunition generates even higher pressures and is generally not recommended for use in the Glock 19 due to the increased risk of damage to the firearm.

Ammunition Storage

Proper ammo storage is crucial for maintaining its reliability and longevity. Store ammunition in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing ammunition in humid environments, as moisture can degrade the powder and primers, leading to malfunctions. It is also important to store ammunition securely, away from children and unauthorized individuals.

Ammunition Disposal

Proper ammo disposal is essential for safety and environmental reasons. Never dispose of ammunition in the trash or by burying it. Contact your local law enforcement agency or a reputable gun store for information on how to properly dispose of unwanted ammunition. They may have programs in place for collecting and disposing of ammunition safely.

Troubleshooting Common Ammunition Issues

Even with high-quality ammunition, issues can sometimes arise. Here are some common problems and potential solutions:

Failure to Feed

A failure to feed occurs when the ammo does not properly load into the chamber. This can be caused by a variety of factors, including:

Dirty or damaged magazine: Clean and inspect your magazines regularly to ensure they are free of dirt, debris, and damage.
Weak recoil spring: A weak recoil spring can prevent the slide from cycling fully, leading to a failure to feed. Replace the recoil spring as needed.
Ammunition incompatibility: Some types of ammo may not feed reliably in your Glock 19. Try different brands and types of ammo to see if the problem persists.
“Limp Wristing”: Not holding the gun firmly enough.

Failure to Eject

A failure to eject occurs when the spent casing is not properly ejected from the firearm after firing. This can be caused by:

Dirty or damaged extractor: Clean and inspect the extractor regularly to ensure it is free of dirt, debris, and damage.
Weak extractor spring: A weak extractor spring can prevent the extractor from properly gripping the casing, leading to a failure to eject. Replace the extractor spring as needed.
Ammunition incompatibility: Some types of ammo may not generate enough pressure to cycle the slide fully, leading to a failure to eject. Try different brands and types of ammo to see if the problem persists.

Squib Load

A squib load occurs when the primer ignites the powder charge, but the bullet does not have enough force to exit the barrel. This can be a dangerous situation, as firing another round after a squib load can cause the barrel to burst. If you suspect a squib load, immediately stop shooting and carefully inspect the barrel for obstructions. Never attempt to clear a squib load by firing another round.

Maintaining Your Glock 19 for Optimal Performance

Proper maintenance is essential for ensuring the reliability and longevity of your Glock 19. Here are some key maintenance tasks:

Cleaning

Clean your Glock 19 regularly, especially after shooting. Disassemble the firearm according to the manufacturer’s instructions and clean the barrel, slide, and frame with a quality gun cleaning solvent. Lubricate the moving parts with a gun oil or grease designed for firearms.

Inspection

Inspect your Glock 19 regularly for signs of wear and tear. Check the barrel for cracks or bulges, and inspect the slide and frame for any signs of damage. Replace any worn or damaged parts as needed.
