Introduction to 45 Caliber Handguns
The 45 caliber handgun has been a staple of American firearms for over a century. The origins of the 45 caliber date back to the early 1900s, when the US military adopted the 45 ACP (Automatic Colt Pistol) cartridge for its service pistols. Since then, the 45 caliber has become a popular choice for self-defense, law enforcement, and recreational shooting. In this article, we will compare two popular 45 caliber cartridges: the 45 ACP and the 45 GAP (Glock Automatic Pistol).
45 ACP: The Original 45 Caliber
The 45 ACP was designed by John Browning in the early 1900s for use in the Colt 1911 pistol. The cartridge was intended to be a more powerful alternative to the 38 Long Colt, which was the standard issue sidearm for the US military at the time. The 45 ACP quickly gained popularity among law enforcement and civilians due to its stopping power and manageable recoil.
Characteristics of the 45 ACP:
- Bullet diameter: 0.452 inches
- Case length: 0.898 inches
- Overall length: 1.275 inches
- Muzzle velocity: 850-950 feet per second
- Muzzle energy: 350-400 foot-pounds
45 GAP: The New Kid on the Block
The 45 GAP was introduced in 2003 by Glock, Inc. as a more efficient and reliable alternative to the 45 ACP. The 45 GAP was designed to operate at higher pressures than the 45 ACP, resulting in a more compact cartridge with similar performance.
Characteristics of the 45 GAP:
- Bullet diameter: 0.452 inches
- Case length: 0.755 inches
- Overall length: 1.070 inches
- Muzzle velocity: 900-1000 feet per second
- Muzzle energy: 350-400 foot-pounds
Comparison of 45 ACP and 45 GAP
Both the 45 ACP and 45 GAP are popular choices for self-defense and recreational shooting. However, there are some key differences between the two cartridges.
- Length: The 45 GAP is shorter than the 45 ACP, making it more suitable for compact pistols.
- Pressure: The 45 GAP operates at higher pressures than the 45 ACP, resulting in a more efficient cartridge.
- Recoil: The 45 GAP has slightly less recoil than the 45 ACP due to its more efficient design.
- Accuracy: Both cartridges are known for their accuracy, but the 45 ACP has a slightly longer effective range due to its heavier bullet.
💡 Note: The 45 GAP is not as widely available as the 45 ACP, and may be more difficult to find in certain regions.
Which 45 Caliber Reigns Supreme?
Ultimately, the choice between the 45 ACP and 45 GAP comes down to personal preference and intended use. If you prioritize a more compact pistol with similar performance to the 45 ACP, the 45 GAP may be the better choice. However, if you prefer a more traditional 45 caliber cartridge with a longer effective range, the 45 ACP may be the better option.
When to Choose the 45 ACP:
- You prioritize a longer effective range
- You prefer a more traditional 45 caliber cartridge
- You have a pistol designed specifically for the 45 ACP
When to Choose the 45 GAP:
- You prioritize a more compact pistol
- You want a cartridge with similar performance to the 45 ACP but with less recoil
- You have a pistol designed specifically for the 45 GAP
