What is 9mm Ammo?
The 9mm (9x19mm Parabellum) is the most popular handgun round in the world. It’s used by police, military, and civilians alike due to its reliability, manageable recoil, and high magazine capacity.
Benefits of 9mm:
- Lower recoil – easier for beginners and faster follow-up shots
- Higher capacity – more rounds per magazine
- Affordable – generally cheaper than .45 ACP
- Widely available – easy to find in stores and online
9mm ammo is great for self-defense, target shooting, and concealed carry. It's lightweight and offers good stopping power with modern hollow point rounds.
What is .45 ACP Ammo?
The .45 ACP (Automatic Colt Pistol) is a large-caliber round known for its heavy bullet and serious stopping power. Developed by John Browning, it has been used for over a century, including in the classic 1911 pistol.
Benefits of .45 ACP:
- Larger bullets – heavier rounds with deeper impact
- Proven stopping power – excellent for close-range defense
- Slower velocity – reduces over-penetration risks
- Trusted by professionals – used in law enforcement and military
.45 ACP ammo is ideal for those who prioritize stopping force over magazine capacity.
