What’s the Best Grain for 9mm? Our 9mm Ammo Experts Help You Decide!

If there were one best grain for 9mm, then that’s all manufacturers would offer. Since that’s obviously not the case, one can only conclude there are the best bullet weights for specific instances.

Our ammo experts spent hours testing and researching the best 9mm grain weight. Read on to learn which grain is best for specific use cases!

What’s the Best Grain for 9mm?

In most instances, the best grain for 9mm is 115. It’s readily available and reasonably inexpensive, though it’s rarely ideal for self-defense, and it’s wholly inappropriate when subsonic performance is desired.

Best Grain for 9mm by Use Case

115 grain 9mm ammo is a great choice for many applications and a poor choice for others. In this section, we’ll discuss what your options are when 115 grain ammo isn’t ideal.

Target Shooting & Range

I usually reach for 115 grain 9mm ammo when I’m heading to the range for a little target shooting. I appreciate that it’s regularly in stock and rarely overpriced. I’m comfortable target shooting with it, but in some instances it has more recoil than other 9mm rounds.

Why is the 115 grain bullet so well-suited for target shooting? Largely because it’s the lightest bullet you will normally find in factory-loaded 9mm ammunition, which means three things:

1. It’s cheaper by virtue of the fact that it contains less lead and copper, thus reducing production costs.
2. It allows manufacturers to invest less fuel in transporting raw materials and finished products.
3. Its lighter weight permits a relatively higher muzzle velocity, which translates to the flatter trajectory that simplifies aiming.

The next time you’re headed to the range for a day of target shooting, stock up on 115 grain 9mm ammo!

Concealed Carry & Self-Defense

I prefer carrying 135 grain 9mm bullets for self-defense because they’re accurate, dependable, and pack a punch. Most 9mm concealed carry enthusiasts recommend a 124 to 147 grain bullet for self-defense. I’m confident carrying a weight in the middle of that range.

The most important consideration for choosing self-defense ammo is not necessarily the weight, but the design of the bullet itself. Choosing a bullet based on its capacity for achieving sufficiently deep penetration and undergoing rapid, wide terminal expansion is much better than choosing a bullet solely on weight.

That said, a heavier bullet has more momentum, which improves its ability to penetrate barriers and soft tissue, and subsonic muzzle velocities have a softer report than the piercing crack common to high velocity 9mm ammo. This will have less negative impact on your hearing during a self-defense situation, when you don’t have time to put hearing protection on.

Test which bullet functions best in your pistol, and determine which you feel most confident firing. That’s necessarily your best choice for defense.

Competition Shooting

Most competition shooters prefer to handload 124 or 147 grain 9mm bullets. Some prefer massive 160 grain bullets. Very few use 115 grain bullets, as their recoil is often perceived as overly snappy.

There are many different rules for each shooting competition and division. These may make one bullet weight a better option than others. Personal preference is also important. Just because others prefer 124 grain bullets doesn’t mean you necessarily will.
