5 Choices of the Best 9mm Self Defense Ammo, All Used by Law Enforcement

9mm self defense ammo

Your life and the lives of those you protect depend on it: use one of these time-tested hollow point rounds preferred by U.S. law enforcement for your 9mm self defense ammo.

The good news: Top ammo manufacturers have worked tirelessly to develop law enforcement ammo that provides amazing performance for self defense.

The bad news: With so many rounds, tests, and data, finding the best 9mm self defense ammo can be a daunting task.

The best news: Law enforcement rounds are just a manufacturing label. In most cases, they can also be used by civilians.

When it comes to self defense rounds, ammo makers are always looking for the optimal balance between reliability, velocity, expansion, penetration and weight retention.

Too much expansion can cause issues penetrating some barriers such as glass, metal or clothing. Not enough expansion and you lose effective stopping power.  Reliable performance and consistent feed rates are critical.

With these factors in mind, here’s a breakdown of the 5 best self defense rounds that are widely available for civilian use. These products have also been verified to be used by law enforcement agencies in the U.S.

The ammo listed below includes a variety of sizes that enable shooters to find an optimal round for their 9mm.

9mm Ballistics Testing

With so many types of ammo available, it’s difficult to find one conclusive form of testing for every product. You can still piece together useful data from several excellent resources available online.

Lucky Gunner has done a comprehensive ballistic test that includes 9mm ammo.  Range Hot did a test of several popular 9mm rounds.

Choosing the Right 9mm round for Your Firearm

Ballistics data and product information is helpful for choosing the right 9mm self defense ammo.  These tests are not conclusive on their own and all of these products have impressive test results.

You should realize that everyone has a different size 9mm and can find themselves in different self defense situations.

That is why it’s important for you to shoot and test ammo in your own firearm.

Test these products to ensure you are accurate and maintain flawless feed rates.

I hope to never shoot my gun in self defense, but when if I do, then I want to be 100% sure I have the ammo to save lives!
