What is the Best Grain Bullet for a 9mm?

The choice of the best grain bullet for a 9mm depends on several factors, including the specific firearm, intended use, and the shooter's personal preferences. Traditionally, the standard 9mm has utilized the 124 grain Luger bullet, but other options like 147 grain and even 115 grain rounds have gained popularity in recent years.

Historical Context and Boiler Plate Ammunition

For a long time, the 9mm Luger cartridge used pointy FMJ (Full Metal Jacket) ammunition, which was often 124 grains in weight. These older guns have loading ramps designed for these types of bullets. However, these designs can sometimes lead to jams when loaded with short, flat-nosed Hollow Point (HP) ammo, such as the lightweight 50 grain Liberty or even 115 grain HP rounds. In modern defensive firearms, specifically those designed for self-protection, the risk of jams with flat-nosed ammunition is minimal.

Current Standard and Performance

The standard 124 grain 9mm Luger bullet is still a reliable option. It is effective and has been the go-to choice for many decades. When it comes to self-defense, a 124 grain or 147 grain HJ (Hollow Point) round is often recommended. Both of these weights provide a balance between penetration and controlled expansion.

Practice and Accuracy

For those engaging in practice and target shooting, a 115 grain FMJ (or copper-coated or polymer) round is a popular choice. It is generally more affordable and reliable for target practice. However, the 115 grain round can pose a challenge in terms of accuracy and controlled expansion in some scenarios. In a moment where the San Diego PD experienced issues with the Federal BPLE 115 grain JHP bullet expanding too quickly, they shifted to the Speer Gold Dot 124 grain JHP, which became the standard for the department. This bullet proved effective in a one-shot stop scenario.

Selection for Self-Defense and Fun Use

For recreational shooting, 147 grain FMJ or copper-coated bullets are commonly used due to their accuracy and low recoil. Relatively, these types of bullets require minimal powder charge, making them ideal for target practice. For those who prioritize self-defense, the 124 grain to 147 grain JHP rounds remain the preferred choice.

Conclusion

The choice of 9mm grain bullet ultimately depends on the situation and the shooter's goals. While there are many opinions on the best variety, opting for any of the well-known brands will yield satisfactory results. Whether it's for fun shooting, target practice, or self-defense, there is a perfect 9mm round for every need.
