5 Key Differences Between .45 Super And .45 Acp

When discussing the world of firearms, the .45 Super and .45 ACP (Automatic Colt Pistol) are two popular cartridges that often pique the interest of enthusiasts. Both are widely used in handguns, especially among those who appreciate the .45 caliber for its stopping power and reliability. However, these two cartridges differ significantly in terms of performance, design, and intended use. In this post, we'll explore five key differences between the .45 Super and .45 ACP, helping you understand which cartridge may best suit your shooting needs. 🏹

1. Power and Performance

One of the most significant differences between .45 Super and .45 ACP is their power levels.

• .45 ACP: This cartridge typically generates muzzle velocities of around 800 to 900 feet per second (fps) and produces energy levels ranging from 350 to 400 foot-pounds. The .45 ACP is known for its manageable recoil and is generally favored for self-defense and target shooting.

• .45 Super: On the other hand, the .45 Super is a higher-pressure round that can reach muzzle velocities of 1,100 to 1,200 fps. With energy levels exceeding 500 foot-pounds, it is designed for those who want a more powerful option while still using a similar platform as the .45 ACP. This increased power can deliver greater stopping potential, making it a popular choice for hunting and personal defense.

2. Case Design and Dimensions

The design and dimensions of the cartridge cases also vary significantly between the .45 Super and .45 ACP.

• .45 ACP: The .45 ACP cartridge has a case length of approximately 0.898 inches and is designed to function well in a standard 1911-style handgun. Its tapered case assists in reliable feeding from magazines.

• .45 Super: In contrast, the .45 Super cartridge is slightly longer with a case length of around 0.900 inches to 0.910 inches. It has a thicker wall and a reinforced design to withstand the higher pressures generated during firing. While the .45 Super can often be fired in .45 ACP chambers (with some modifications), using a firearm specifically chambered for .45 Super is recommended for optimal safety and performance.

3. Recoil and Handling

Recoil is another key difference between these two cartridges, which can significantly affect shooting experience and control.

• .45 ACP: Known for its relatively mild recoil, the .45 ACP is easier to handle, especially for beginners or those not accustomed to shooting higher-powered cartridges. This aspect makes it an ideal choice for recreational shooting and self-defense applications.

• .45 Super: In contrast, the .45 Super generates noticeably more recoil due to its higher power. While many shooters appreciate the increased stopping power, this added recoil may require more practice and a firmer grip for accurate follow-up shots. The adjustment may deter new shooters who are not yet comfortable with managing heavier recoil.

4. Firearm Compatibility

When considering firearm compatibility, the two cartridges can lead to confusion due to their similar dimensions but differing performance characteristics.

• .45 ACP: The .45 ACP is widely compatible with a variety of firearms, including revolvers, pistols, and some carbines. Many manufacturers produce dedicated .45 ACP models, making it one of the most popular cartridges for both personal and recreational use.

• .45 Super: While many .45 ACP firearms can accommodate .45 Super rounds, it is crucial to ensure that the gun is rated for higher pressure. Some firearms may require modifications or specific aftermarket parts to handle .45 Super safely. Therefore, shooters interested in using .45 Super should verify compatibility before purchasing or converting their firearms.

5. Application and Usage

The intended application of each cartridge influences its popularity and choice among shooters.

• .45 ACP: This cartridge is primarily used in self-defense and sport shooting scenarios. Its manageable recoil, proven reliability, and effectiveness against human targets have established it as a go-to choice for many concealed carriers and law enforcement personnel.

• .45 Super: The .45 Super is typically favored by those seeking a higher power for specific applications such as hunting large game or for personal defense against more significant threats. Its powerful nature makes it less common than the .45 ACP, but it serves a niche of dedicated enthusiasts who desire more stopping power from their handguns.
