The Second Amendment has been the center of attention for quite some time now and the focus primarily lands on citizen’s right to self-defense. While hunting, target shooting, and other recreational uses are very popular for firearm owners, self-defense is probably the most important. 

When it comes to protecting yourself, your family, and your property, there are a few things that you want to make sure never fail. First and foremost, you want to make sure your firearm doesn’t fail and performs properly. Second, you want to be comfortable using the firearm safely and effectively. And lastly, you want to make sure that rounds in the magazine and chamber perform how they were designed to. 

While the caliber of the firearm you choose is a personal and performance choice, one very popular size is .45 ACP for self-defense. There are several other options available that all perform very well, like 9mm, .40 S&W, or .357 Magnum. Since there is an abundance of information available and the quantity of products on the market is extremely overwhelming, we’ll focus on the best .45 ACP ammo for self-defense. 

How to Choose the Best .45 ACP Ammo?

Most gun owners will spend considerable time reading, researching, testing, and debating which model and caliber will best suit their needs, and this process is essential. However, the average gun owner will, most likely, spend much less time and thought when picking out the right ammo. 

While hunting or target shooting do not carry the same consequences when the wrong or less than ideal ammunition is chosen, self-defense situations carry life and death consequences. When choosing ammunition, there are a few things to consider, such as:

  • Load/Weight – the amount of propellant that is packed into the round and the weight of the bullet (grains). These two components directly impact the velocity of the bullet as it leaves the barrel and the amount of force that it has upon impact.
  • Expansion – upon impact, the bullet will expand, depending on the design and type, to create an entry wound and inflict damage. 
  • Penetration – this is self-explanatory — how deep the bullet penetrates the intended target. 

Thanks to the wonderful internet, gun enthusiasts, third-party companies, and even government agencies can publish their reviews and testing results of every ammunition available for individuals to research. If it is on the market, you can bet that it has been put through the gauntlet of testing. 

Types of .45 ACP Defense Ammo

As mentioned above, expansion and penetration are two crucial components of a self-defense round’s performance. Both of these aspects translate into the “stopping power” of the round. In consumer terms, this refers to how effective they are at stopping a threat. When faced with a life-threatening situation, you want to be sure that your shot(s) will be capable of stopping a threat, even when the shots are not as well-placed as desired. The types of rounds you can find for .45 ACP defense ammo include:

  • Jacketed Hollow-point (JHP) – these are perhaps the most popular/common self-defense rounds on the market. Hollow points are designed to expand (mushroom effect) when contact with the intended target occurs. The concept relies on the initial shock of the impact that creates pressure in the hollow point of the bullet that causes the soft lead core to expand. This results in a much larger wound path through the target, i.e., stopping power. 
  • Semi-Jacketed Hollow-point (SJHP) – same concept as the JHP’s, but the semi-jacket gives the bullet slightly more uniformity when expanding to create a consistent mushroom effect and a little more penetration.
  • Solid Copper Hollow-point (SCHP) – very similar to normal hollow point rounds, except instead of a lead core, the bullet is all copper. Useful for “lead-free” ranges or hunting areas, SCHPs are much stronger than lead but feature specific designs to ensure proper expansion at the desired penetration depth.
  • Expanding Full Metal Jacket (EFMJ) – these rounds are designed for specific circumstances when softer hollow point designs failed. Certain self-defense rounds can fail to expand or have issues with certain barriers, and the most common one is heavy clothing. 

EFMJ rounds penetrate through barriers because there is no hollow tip to get clogged with threads or other material but upon impact with a noticeable resistance. The bullet design triggers a rubber core to drive into the lead tip, which caused the expansion similar to a hollow point.

What Are the Best Options?

Now, the part that you’ve been waiting for, that we’ve delayed from sharing due to providing lots of useful information to help you make an informed, responsible choice on the best .45 ACP self-defense ammo for your needs. So, here are some of the top brands and types on the market today.

Corbon DPX 160gr – these rounds are SCHP, which means the solid copper core increases the performance when barriers are encountered. The reason these rounds are a superior self-defense choice is that the design features serrations on the internal surface of the cavity. Unlike other hollow points with serrations along the edge, these rounds produce six consistent copper petals on impact, which offers more expansion that other leading hollow points. 

Black Hills Ammunition TAC-XP HP 145gr +P – when it comes to lead-free self-defense rounds, the TAC-XP rounds are among the best available. Tried and tested through various common barriers that consumers may encounter, TAC-XP rounds passed with exceptional results. Due to their lightweight, the muzzle velocity clocks in around 1200 fps, which is a fast round for .45 ACP. 

Speer Gold Dot 185gr JHP Personal Protection – while on the lighter side for typical .45 ACP rounds, these 185gr bullets still pack a hefty punch. Speer designed these with the intention to be a one-shot stopping power round because the expansion of this true hollow point begins immediately on impact. The rapid expansion and deceleration create massive wound cavities that put threats down. 

Federal Guard Dog 165gr EFMJ – these rounds guarantee expansion, every single time. Unlike JHPs, this expanding full metal jacket design is revolutionary because there is no hollow point that can get clogged or caught up as it passes through any potential barriers. 

Barnes TAC-XPD SCHP 185gr +P – this high pressure (+P) round has brought Barnes TAC-XPD to the forefront of self-defense ammunition. Specially tested to be unphased by common barriers such as thick clothing, auto glass, plywood, and sheet metal, these light grain rounds tested out at 1,000 fps. This is a pretty fast velocity for a .45 round that still produces devasting expansion and significantly less recoil that improves any necessary follow-up shot accuracy.

Hornady Critical Duty 220gr JHP FTX +P – Hornady is one of the top self-defense ammunition companies on the market. For 70 years, they have been producing top-notch, revolutionary ammo that has saved lives around the world. 

These heavy rounds have been FBI-tested for penetration standards and provide unmatched impact power. Pressure-loaded, the rounds nearly hit 1000fps, which allows them to create immense wound cavities because the design enables the hollow point to expand rapidly upon impact. With superior penetration through various barriers, you can bet your life that Hornady rounds will perform when you need it most. 

Magtech First Defense 165gr SCHP +P – Magtech has pressure-loaded this very lightweight round to deliver exceptional performance for self-defense with velocities of 1100fps and over 440 foot-pounds of energy. The solid copper hollow point allows the Magtech rounds to effectively penetrate through various barriers while still producing a consistent mushroomed bullet upon impact with the target. Rapid expansion is crucial when trying to stop a threatening target and Magtech spared no expense on these First Defense round designs. 

Winchester 230gr JHP ACP PDX-1 Defender – When it comes to passing the FBI’s rigorous testing, the PDX-1 Defender rounds did so with flying colors. Winchester has produced a round capable of blasting through any potential barriers (clothing, plywood, auto glass, etc.) and still achieve a devasting blow to the intended target.
