When considering what 9mm ammunition to purchase, one of the key considerations is the grain weight of the projectile. While it may be tempting to simply opt for the cheapest available option, it is important to understand the differences between 115 grain and 124 grain 9mm bullets in order to make an informed decision about which is the best for your needs.

The grain weight of a bullet is the unit of measurement used to describe the mass of the projectile. The grain measurement is an old system, with one grain equaling 1/7000th of a pound, and it is the most commonly used method to describe the weight of a bullet.

The grain weight of a 9mm bullet typically ranges from 115 to 147 grains, with 115 and 124 grains being the most common weights. The difference between the two is the mass of the projectile, with the 115 grain bullet weighing 0.0077 ounces less than the 124 grain bullet.

Performance

The performance of a bullet is determined by the combination of its mass, velocity, and shape. As the grain weight increases, the bullet becomes heavier, meaning that it has a higher momentum. This higher momentum allows the bullet to penetrate targets more effectively, making the 124 grain 9mm bullet more effective for defensive purposes than the 115 grain version.

In terms of velocity, the 115 grain 9mm bullet has a higher muzzle velocity than the 124 grain version, meaning that it is capable of travelling further and faster. This higher velocity also makes the 115 grain bullet more accurate at longer distances, making it a better choice for target shooting.

Recoil

The recoil of a firearm is the force that pushes back against the shooter when the weapon is fired. The higher the grain weight, the more momentum the bullet has, and the more recoil the shooter will feel. As the 124 grain 9mm bullet has a higher momentum than the 115 grain version, it produces more recoil when fired. This can make the 124 grain bullet less comfortable to shoot, particularly for novice shooters.

Conclusion

When considering which 9mm ammunition to purchase, it is important to understand the differences between 115 grain and 124 grain bullets. The 124 grain bullet has a higher momentum, making it more effective for defensive purposes. However, it also produces more recoil, making it less comfortable to shoot. The 115 grain bullet has a higher velocity, making it more accurate at longer distances and more suitable for target shooting. Ultimately, the best choice for a particular shooter will depend on their needs and preferences.

Difference in Weight

The 9mm round is available in two bullet weights: 115 Grain and 124 Grain. The weight difference between the two is 9 grains. This might not seem like much, but it can have a significant effect on the performance of the round. The 115 grain bullet has a lighter weight, and therefore a higher velocity, than the 124 grain bullet. This can translate to increased accuracy and energy transfer on target.

Difference in Price

The difference in weight between 115 grain and 124 grain 9mm rounds also has an impact on the price. In general, the lighter weight 115 grain rounds will be more affordable than the 124 grain rounds. This is due to the fact that the manufacturing costs for the 115 grain rounds are lower, due to the lighter bullet weight.

Difference in Recoil

The weight difference between the 115 grain and 124 grain 9mm rounds also has an effect on the recoil of the round. The lighter weight bullet will produce less felt recoil than the heavier bullet. This can be beneficial for shooters who are recoil-sensitive, or for those who are shooting in a low-recoil environment such as a shooting range. The lighter weight bullet will also have a faster follow-up shot time due to the reduced recoil.
