HANDGUN AMMO

About Handgun Ammo

The evolution of handgun ammunition spans centuries, tracing a remarkable journey of innovation that began with simple black powder and lead shot in the 16th century.

Early handguns were rudimentary, single-shot weapons requiring loose powder and ball, often plagued by inconsistent performance and poor accuracy due to smoothbore barrels.

These challenges ignited a continuous pursuit of better performance—and ultimately led to the creation of the modern handgun ammo we know today.

A major leap forward came in the mid-1800s with the development of metallic cartridges, combining the primer, powder, and bullet into a single brass or copper casing. This breakthrough transformed handgun functionality, enabling faster loading, greater reliability, and a significant improvement in overall shooting efficiency.

Popular rounds like the .22 Short, first produced in 1857, became a foundation for modern rimfire cartridges, while the later adoption of centerfire rounds—like the iconic .45 Colt—fueled the rise of revolvers and single-action pistols in the American West.

By the early 20th century, cartridges such as the 9mm Luger and .45 ACP emerged as global standards for military and law enforcement use, while revolver calibers like the .357 Magnum and .44 Magnum became renowned for their power and versatility.

The innovation didn’t stop there—handgun ammo continued to evolve with specialized options for self-defense, sport shooting, hunting, and competition.

Today, modern handgun and pistol ammunition is as diverse as the firearms they feed. From popular calibers like 9mm, .380 ACP, and .40 S&W, to niche rounds such as the .454 Casull and 7.62x25 Tokarev, there is an ideal round for every application.

Most cartridges maintain the same basic construction—a casing, primer, powder, and bullet—but bullet shapes, materials, and load specifications vary widely depending on intended use.

From its humble beginnings to the high-performance rounds of today, handgun ammunition represents a legacy of constant innovation.

It's not just about putting lead downrange—it's about precision, reliability, and purpose-built performance for every shooter.

Types of Handgun Ammunition

When choosing handgun ammunition, it’s essential to understand the differences between the various types of bullets. Each type serves a unique purpose, from target practice to self-defense or specialty uses.

Here's an overview of some of the most common types of handgun ammo:

FMJ (Full Metal Jacket)
FMJ ammunition is one of the most common and affordable types of handgun ammo, ideal for target practice, training, and general shooting activities. In FMJ rounds, the bullet is encased in a metal jacket (typically copper), which prevents the lead core from being exposed.

This design allows for smooth feeding and reliable cycling in semi-automatic pistols. FMJ rounds are known for their high penetration, which means they can pass through targets with minimal expansion, making them less suitable for self-defense purposes.

Key Features:

• Ideal for target practice and training.
• High penetration and reliable feeding.
• Less expansion upon impact, making it unsuitable for self-defense.

JHP (Jacketed Hollow Point)
JHP ammunition is designed primarily for self-defense and law enforcement use. These rounds feature a hollowed-out tip that expands upon impact, creating a larger wound channel and increasing the bullet’s stopping power.

The expansion reduces the likelihood of over-penetration, which makes JHP rounds safer for self-defense in urban environments, where there’s a risk of hitting unintended targets behind the assailant. JHP ammo delivers excellent energy transfer, making it ideal for defensive situations.

Key Features:

• Designed for self-defense and law enforcement.
• Expands upon impact, creating a larger wound cavity.
• Reduces the risk of over-penetration.
• Excellent stopping power.

TMJ (Total Metal Jacket)
TMJ ammunition is similar to FMJ but with one key difference: the bullet is fully enclosed in a metal jacket, including the base. This helps minimize lead exposure, which is especially important for indoor range shooters or those concerned with lead residue.

TMJ rounds are commonly used in environments where lead exposure needs to be minimized. While TMJ offers the same high penetration as FMJ, the benefit lies in the cleaner shooting experience.

Key Features:

• Fully encapsulated in metal, including the base.
• Reduces lead exposure, ideal for indoor shooting.
• Offers high penetration, like FMJ.
• Often used for target practice in controlled environments.

Tracer
Tracer ammunition contains a special pyrotechnic compound in the base of the bullet that ignites when fired, creating a visible trail of light as the bullet travels downrange. This feature makes tracer rounds perfect for military, law enforcement, or tactical training, as it allows shooters to visually track their shots and make adjustments during shooting.

Tracers are also used for signaling and marking targets during military operations. However, they tend to have slightly different ballistics than standard ammo and can be more expensive.

Key Features:

• Emits a visible trail, helping shooters track shots.
• Used in tactical training and military operations.
• Ideal for marking targets or signaling.
• Can be more expensive than standard rounds.
