.45 Super: High-Performance Handgun Round

The .45 Super is a high-pressure variant of the .45 ACP cartridge, designed to offer increased velocity and energy while maintaining compatibility with many existing .45 ACP firearms. Developed in the late 1980s by Dean Grennell, the .45 Super pushes the boundaries of .45 caliber handgun performance, offering ballistics that approach those of the .44 Magnum in a semi-automatic platform.

Development and Characteristics

The .45 Super was created to address the limitations of the .45 ACP in terms of velocity and energy. By utilizing a stronger case and higher operating pressures, the .45 Super achieves velocities up to 1,300 fps with 230-grain bullets, compared to the typical 850-950 fps of standard .45 ACP loads. This results in significantly increased muzzle energy, typically ranging from 500 to 600 ft-lbs, making it suitable for hunting medium game and providing enhanced stopping power for self-defense scenarios.

While dimensionally similar to the .45 ACP, the .45 Super requires firearms specifically built or modified to handle its higher pressures. This typically involves a stronger recoil spring, a fully supported chamber, and potentially a heavier slide. The cartridge uses small pistol primers instead of the large pistol primers found in .45 ACP, which helps contain the higher pressures generated by the round.

Applications and Adoption

The .45 Super has found a niche among handgun enthusiasts seeking magnum-level performance from a semi-automatic platform. It's particularly popular for hunting, where its high energy and flat trajectory make it effective against medium-sized game at moderate ranges. In self-defense applications, the .45 Super offers increased penetration and expansion potential compared to standard .45 ACP loads.

Despite its performance advantages, the .45 Super remains a relatively specialized cartridge. Its higher recoil and the need for firearm modifications have limited its widespread adoption. However, it continues to have a dedicated following among handloaders and those seeking maximum performance from a .45 caliber semi-automatic handgun.

Frequently Asked Questions:

Q: What is .45 Super?

A: .45 Super is a cartridge developed in 1988 by Dean Grennell. It is dimensionally identical to .45 ACP but loaded to higher pressures, resulting in increased velocity and energy.

Q: Can I shoot .45 Super in a standard .45 ACP pistol?

A: No. .45 Super generates significantly higher pressures than .45 ACP and requires a firearm specifically designed or modified to handle these increased pressures. Using .45 Super in a standard .45 ACP pistol can be dangerous and may cause catastrophic failure.

Q: What are the ballistic advantages of .45 Super over .45 ACP?

A: .45 Super typically achieves velocities 200-300 fps higher than .45 ACP with the same bullet weight. For example, a 230-grain bullet in .45 Super can reach velocities of 1,100 fps or more, compared to around 850 fps for .45 ACP.

Q: What modifications are needed to shoot .45 Super?

A: To safely shoot .45 Super, a pistol typically needs a stronger recoil spring, a fully supported chamber, and potentially a heavier slide. Some manufacturers offer conversion kits or purpose-built .45 Super pistols.

Q: Is .45 Super suitable for self-defense?

A: .45 Super can be effective for self-defense due to its increased energy and penetration compared to .45 ACP. However, the increased recoil and muzzle blast may make follow-up shots more difficult for some shooters. It's also less common, which may affect ammunition availability.
