What is 9mm Ammo?

9mm ammo is a type of ammunition used in handguns and some rifles. It is one of the most popular calibers for self-defense, target shooting, and law enforcement use. 9mm ammo typically comes in two types: full metal jacket (FMJ) bullets or hollow point bullets.

Definition of 9mm Ammo

The term “9mm” refers to the caliber size of the bullet; it measures 0.355 inches in diameter and can be loaded into a variety of handgun models including semi-automatics, revolvers, and derringers. The cartridge case itself usually contains gunpowder that propels the bullet out when fired from a firearm.

Types of 9mm Ammo

Full Metal Jacket (FMJ) Bullets are made with an outer shell that completely encases the lead core inside which prevents expansion upon impact with a target. FMJ rounds are best suited for range training as they have less recoil than other types due to their lighter weight but do not expand on impact making them less effective at stopping power compared to other types such as hollow points or frangible rounds.

Hollow Point Bullets feature an open cavity at their tip which allows them to expand upon contact with soft tissue targets like humans or animals providing greater stopping power than FMJ rounds while also reducing over penetration risks since they will not pass through walls or other barriers after hitting their intended target(s). Hollow points are more expensive than FMJ rounds but offer better performance for self defense purposes due to their increased accuracy and expanded wound channel created by its expanding design upon contact with soft tissue targets like humans or animals.

Advantages of 9mm Ammo

In conclusion, 9mm ammo is a popular choice for self defense due to its power and affordability. It comes in two main types – Hollow Point and Full Metal Jacket – which have their own advantages and disadvantages depending on the situation. Now let’s take a look at the differences between these two bullet types.

Key Takeaway: 9mm ammo is a popular caliber for self-defense, target shooting and law enforcement use due to its accuracy, stopping power and reduced risk of over penetration. It comes in two types: Full Metal Jacket (FMJ) bullets or Hollow Point Bullets which offer different levels of performance depending on the application. FMJ rounds are best suited for range training while hollow points are more effective at stopping power and better suited for self defense purposes.

Hollow Point vs. Full Metal Jacket (FMJ)

Hollow Point vs. Full Metal Jacket (FMJ) bullets are two of the most popular types of ammunition used for self defense. The differences between them can be quite significant, and it is important to understand which type is best suited for your particular needs.

Differences between Hollow Point and FMJ Bullets:

Hollow point bullets have a hollowed out cavity in their tip that causes them to expand upon impact with a target, creating more damage than an FMJ bullet would. This expansion also helps prevent over-penetration through walls or other barriers, making it safer for bystanders when shooting indoors or in close quarters. On the other hand, FMJ bullets do not expand upon impact and instead penetrate deeper into a target before stopping.

Pros and Cons of Hollow Point and FMJ Bullets:

One advantage of using hollow points is that they cause more tissue damage than an FMJ bullet due to their expansion on impact with a target. This makes them better suited for self defense situations where you need maximum stopping power quickly. However, they may not penetrate deep enough if you are trying to shoot through thick clothing or armor plating as they will likely stop after hitting these materials rather than continuing on into the body like an FMJ round would do. Additionally, hollow points tend to cost more than standard full metal jacket rounds due to their increased effectiveness at shorter distances compared to longer ones where penetration depth matters more than wound size does

In general, hollow point rounds should be used when defending yourself at close range against multiple attackers or in any situation where quick incapacitation is desired without risking over-penetration through walls or other barriers behind your intended target(s). Conversely, full metal jacket rounds should be used when engaging targets at longer ranges since their greater penetration depth will ensure adequate tissue damage even if the attacker is wearing thicker clothing or armor plating that could otherwise impede the performance of a hollow point round.

Hollow point and FMJ bullets have their own advantages and disadvantages for self defense. While hollow points are designed to expand upon impact, FMJs are made to penetrate deeply. Knowing when to use each type of bullet can be the difference between life and death in a dangerous situation. Now let’s take a look at some of the deadliest 9mm ammo brands available on the market today.

Key Takeaway: Hollow point and FMJ bullets are two popular types of ammunition used for self defense. Hollow points cause more tissue damage but can be stopped by thick clothing or armor, while FMJ rounds penetrate deeper and should be used when engaging targets at longer ranges.

Best Practices When Choosing and Storing Your Self Defense Ammunition

When it comes to self defense, having the right ammunition is essential. The type of ammo you choose can have a huge impact on your safety and the effectiveness of your weapon in an emergency situation. Here are some factors to consider when choosing your self defense ammunition:


Choosing the right caliber for your firearm is important. Different calibers offer different levels of power and accuracy, so make sure you select one that meets your needs. Consider what type of environment you’ll be using it in as well – if you’re shooting outdoors, a larger caliber may be more suitable than something smaller like .22LR or 9mm Luger.

Bullet Type:

There are several types of bullets available for use with firearms, including full metal jacket (FMJ), hollow point (HP) and soft point (SP). FMJ rounds are designed for target practice and general range use; HP rounds expand upon impact to cause maximum damage; SP rounds provide better accuracy at longer distances due to their heavier weight but still expand upon impact like HPs do. Selecting the appropriate bullet type will depend on where and how you plan on using it most often.

Velocity refers to how fast a bullet travels after being fired from a gun, while energy measures its destructive potential when impacting an object or person. Generally speaking, higher velocity means greater stopping power but also increased recoil which could affect accuracy depending on the shooter’s skill level or experience with firearms handling techniques such as trigger control and sight alignment/picture development etc. Higher energy means more penetration capability which could be beneficial in certain scenarios such as home defense against multiple assailants wearing body armor or other protective gear that would otherwise stop lower-energy projectiles from doing any real damage beyond superficial wounds/injuries etc.

When storing self defense ammunition safely there are several things to keep in mind:

When storing self defense ammunition safely there are several things to keep in mind: Store Ammunition Separately From Firearms; it is important not only for safety reasons but also because exposure to moisture can cause corrosion over time if stored together with guns for extended periods without proper protection from humidity and moisture buildup inside storage containers or lockers. Additionally, keeping them separate helps reduce confusion during times when quick access is needed since they won’t all look alike – i.e., magazines vs boxes of loose cartridges – making identification easier under stress filled situations where split second decisions need made quickly without hesitation due lack of clarity caused by clutter or disorganization within storage areas containing both items simultaneously.

Storing ammunition securely locked away helps prevent unauthorized persons from accessing them, potentially leading to dangerous situations involving misuse resulting in serious injury or death. This can occur either directly through accidental discharge(s) occurring while mishandling loaded weapons improperly, or indirectly via theft whereby criminals gain possession and then commit crimes utilizing stolen property. This puts innocent bystanders at risk, sometimes even resulting in fatalities. Therefore, it is important to take necessary precautions accordingly.

Key Takeaway: When choosing the right self defense ammo, consider caliber, bullet type and velocityenergy to ensure you have the most effective round for your environment. Store ammunition separately from firearms in a secure location to reduce confusion and prevent unauthorized access.
