Understanding the Basics: A Primer on Handgun Ammunition
The world of firearms, specifically handguns, is a complex and multifaceted one. Central to the safe and effective use of any handgun is the ammunition it fires. Choosing the right ammunition isn’t just about finding something that fits; it’s a critical decision impacting accuracy, performance, and, most importantly, the user’s safety and the outcome in any self-defense scenario. This comprehensive guide delves deep into the realm of the most common handgun ammo, equipping you with the knowledge to make informed decisions. We’ll explore popular calibers, bullet types, and crucial factors to consider when selecting the best round for your needs.
Before diving into specific calibers and bullet types, it’s essential to grasp some fundamental concepts. A handgun round, commonly referred to as a cartridge, comprises several key components: the bullet, the casing, the propellant (gunpowder), and the primer. The bullet is the projectile that exits the barrel, the casing holds all the components together, the propellant provides the energy that drives the bullet, and the primer ignites the propellant. These components work in concert to deliver the bullet downrange.
The term “caliber” refers to the diameter of the bullet, typically measured in inches or millimeters. This measurement is critical, as it determines which cartridges are compatible with a particular firearm. Using the wrong caliber can lead to malfunctions, injuries, or even catastrophic failures of the firearm.

Developed in the early 20th century, it was the primary sidearm cartridge for the United States military for many years. The .45 ACP is known for its substantial stopping power. The large-diameter bullet imparts significant energy upon impact, often resulting in a quick incapacitation of the target.
The .45 ACP’s effectiveness is a key reason for its continued popularity, especially for self-defense purposes. However, the cartridge typically has a higher recoil than the nine-millimeter. While some consider this a drawback, many shooters find it manageable. The .45 ACP’s popularity has led to a wide selection of handguns and ammunition, ensuring availability in the market. It remains a favorite among enthusiasts who value a cartridge with a proven track record for effective stopping power.
The Versatile Forty Smith & Wesson
The .40 Smith & Wesson, often called the .40 S&W, is a relatively newer cartridge that emerged in the late 20th century. It was developed as a joint venture between Smith & Wesson and Winchester. The .40 S&W aimed to bridge the gap between the nine-millimeter and the .45 ACP, offering a balance of performance and controllability. It gained rapid popularity with law enforcement agencies, who were attracted by its performance and the availability of existing nine-millimeter platforms that could be easily adapted.
The .40 S&W delivers good stopping power and boasts a flatter trajectory compared to some other calibers, which is beneficial for accuracy at longer ranges. However, the .40 S&W experiences a sharper recoil impulse than the nine-millimeter. While its popularity has declined somewhat in recent years, it remains a viable choice for self-defense and remains a favorite of many shooters.
The Time-Tested Thirty Eight Special
The .38 Special is a venerable revolver cartridge that has been around for over a century. Initially designed for revolvers, it remains a staple for many shooters and is known for its low recoil and good accuracy. The .38 Special’s moderate power level makes it suitable for a wide range of shooters, including those new to handguns. This cartridge is perfect for concealed carry due to its manageable recoil and the variety of compact revolvers chambered for it.
The .38 Special has been a favored choice of law enforcement and civilian shooters for many years. It is widely available, and offers a good balance between performance and ease of use. The .38 Special is a reliable, accurate, and easy to shoot, making it an attractive option for those seeking a classic revolver experience.

The .357 Magnum represents a significant step up in power from the .38 Special. Developed by Smith & Wesson in the mid-20th century, it was designed to deliver exceptional stopping power and long-range performance. It is often used in revolvers and provides impressive velocity and energy.
The .357 Magnum is known for its effectiveness against a variety of targets, including big game. It is suitable for self-defense and hunting. However, the recoil associated with this cartridge is considerably more intense, which can make it challenging for some shooters to control. The .357 Magnum is a very powerful cartridge, and requires good shooting discipline.
Understanding Bullet Types: The Anatomy of a Round
Beyond the caliber, the bullet itself plays a significant role in the overall performance of handgun ammunition. Various bullet types are designed to optimize specific outcomes, such as penetration, expansion, or accuracy. Understanding these bullet types is essential for making informed choices.
Full Metal Jacket: The Workhorse of Training
The Full Metal Jacket (FMJ) bullet features a lead core encased in a copper or steel jacket. This design promotes reliable feeding, reduces barrel wear, and allows for deeper penetration. FMJ rounds are generally cost-effective. The FMJ is the most common type of ammunition for target practice and training exercises because it is inexpensive and reliable. They don’t expand upon impact, which makes them a suitable option for ranges.
Hollow Point: Designed for Stopping Power
Hollow Point (HP) bullets are engineered to expand upon impact, creating a larger wound cavity and transferring more energy to the target. The hollow cavity at the tip of the bullet causes it to deform and expand, slowing down the bullet while increasing the size of the wound channel. This expansion dramatically increases stopping power and reduces the risk of over-penetration, making them a preferred choice for self-defense. Hollow points are designed to maximize the damage potential of the projectile.
Jacketed Hollow Point: Blending Expansion and Performance
Jacketed Hollow Point (JHP) bullets combine the benefits of a jacketed bullet with the expansion properties of a hollow point. They are made with a lead core and a copper jacket, and have a hollow point that causes the bullet to expand upon impact. JHPs offer enhanced expansion and stopping power, while maintaining more controlled penetration than a standard hollow point. This design gives a balanced approach to bullet performance.
Other Options: Exploring Specialized Rounds
Several specialized bullet types are available, each designed for specific purposes. Flat nose bullets often used in revolvers, offer excellent accuracy, and may provide improved performance when used in situations that require a controlled terminal effect. Wadcutter bullets, characterized by their flat front, are a favorite among target shooters due to their precision and clean hole punches in paper targets.
