The Glock 19, a compact and highly popular handgun, is chambered in 9x19mm Parabellum, commonly referred to as 9mm. Choosing the right 9mm ammo for your Glock 19 depends heavily on your intended use – target practice, home defense, or concealed carry. This guide will break down the key considerations to help you make an informed decision.
What Types of 9mm Ammo Are Available for My Glock 19?
The sheer variety of 9mm ammunition available can be overwhelming. Let's categorize the most common types:
-
Full Metal Jacket (FMJ): These rounds have a lead core fully encased in a metal jacket. FMJs are relatively inexpensive, penetrate deeply, and are suitable for target practice. However, they are not ideal for self-defense due to their over-penetration potential.
-
Jacketed Hollow Point (JHP): These rounds have a lead core partially or fully exposed at the tip, creating a hollow cavity. Upon impact, the JHP expands, transferring more energy to the target and reducing over-penetration. This makes them a preferred choice for self-defense and home protection. Many variations exist within JHP, such as:
- Hollow Point: The classic design, offering reliable expansion.
- Controlled Expansion: Designed to expand reliably even at lower velocities.
- Advanced JHP Designs: These often feature engineered designs to optimize expansion and penetration.
-
Full Metal Jacket Hollow Point (FMJHP): This less common round combines features of both FMJ and JHP, aiming to provide a balance between penetration and expansion.
-
+P and +P+ Ammunition: These rounds generate higher pressures than standard 9mm ammunition. While offering increased velocity and stopping power, they should only be used if your Glock 19 is specifically rated for +P or +P+ loads. Using higher-pressure ammo in a firearm not designed for it can cause damage to the weapon.
What is the Best 9mm Ammo for Self-Defense with My Glock 19?
Choosing self-defense ammunition is a critical decision. You need rounds that reliably expand, minimizing over-penetration while maximizing stopping power. Many reputable manufacturers produce high-quality JHP ammunition specifically designed for self-defense. However, it's crucial to test different brands and loads with your specific Glock 19 to see what performs best in your firearm.
What 9mm Ammo is Best for Target Practice with My Glock 19?
For target practice, cost-effectiveness is often a priority. FMJ ammunition is the most affordable option. Its consistent performance and lower cost allow for more practice rounds without breaking the bank.
What Grain Weight of 9mm Ammo Should I Use in My Glock 19?
Grain weight refers to the weight of the projectile (bullet). Common grain weights for 9mm ammunition range from 115 to 147 grains. Lighter grain weights (115-124 grains) generally offer higher velocities and flatter trajectories, while heavier grain weights (147 grains) provide more substantial recoil management and potentially better penetration. The optimal grain weight depends on personal preference and intended use.
How Do I Choose the Right 9mm Ammo for Concealed Carry?
Concealed carry ammunition requires a balance of performance and reliability. JHP rounds are commonly chosen for their expansion characteristics and reduced over-penetration compared to FMJ. However, factors like bullet weight, and the manufacturer's reputation are crucial. Consider factors like ease of handling in a self-defense scenario and the reliability of the ammunition under various environmental conditions.
Is all 9mm ammo compatible with my Glock 19?
While most standard-pressure 9mm ammunition will function reliably in a Glock 19, it’s crucial to always check your firearm's owner's manual for recommendations on ammo types and grain weights. Never use +P or +P+ ammunition unless explicitly stated as compatible by the manufacturer. Using unsuitable ammunition can result in malfunction, damage, or even injury.

Always consult your Glock 19's owner's manual and seek professional guidance from a qualified firearms instructor before making any decisions about ammunition selection. Responsible gun ownership includes thorough knowledge of your firearm and ammunition.
