The world of firearms is filled with various calibers, each with its own unique characteristics and advantages. Among the most popular pistol calibers are the.45 ACP and.45 GAP. While both calibers share some similarities, they also have distinct differences that set them apart. In this article, we'll delve into the world of.45 ACP vs.45 GAP, exploring their history, design, performance, and practical applications to determine which pistol caliber reigns supreme.

A Brief History of.45 ACP and.45 GAP
The.45 ACP (Automatic Colt Pistol) was designed by John Browning in the early 20th century for use in the Colt 1905 pistol. It quickly gained popularity due to its stopping power and moderate recoil. The.45 ACP became the standard-issue sidearm for the United States military from 1911 to 1985.
In contrast, the.45 GAP (Glock Auto Pistol) was developed in the 1990s by CCI/Speer and Glock as a replacement for the.45 ACP. The.45 GAP was designed to offer similar performance to the.45 ACP but with a shorter overall length, making it more suitable for compact pistols.
Design and Ballistics

The.45 ACP and.45 GAP share some similarities in terms of design, but they also have distinct differences.
- Case length: The.45 ACP has a case length of 0.898 inches, while the.45 GAP has a shorter case length of 0.755 inches.
- Bullet weight: Both calibers can accommodate a wide range of bullet weights, but the.45 ACP is typically loaded with heavier bullets (230-250 grains) while the.45 GAP is loaded with lighter bullets (185-200 grains).
- Velocity: The.45 ACP typically has a higher muzzle velocity than the.45 GAP, especially when loaded with heavier bullets.
Performance Comparison
In terms of performance, both calibers have their strengths and weaknesses.
- Stopping power: The.45 ACP is known for its excellent stopping power, thanks to its large diameter and heavy bullet weight. The.45 GAP, on the other hand, has a slightly lower stopping power due to its lighter bullet weight.
- Recoil: The.45 ACP is known for its moderate recoil, while the.45 GAP has a slightly snappier recoil due to its lighter bullet weight.
- Accuracy: Both calibers are capable of excellent accuracy, but the.45 ACP may have a slight edge due to its heavier bullet weight and longer case length.
Practical Applications

Both the.45 ACP and.45 GAP have practical applications in various fields.
- Self-defense: Both calibers are popular for self-defense due to their stopping power and moderate recoil.
- Law enforcement: The.45 ACP is widely used by law enforcement agencies due to its proven track record and stopping power.
- Competitive shooting: The.45 ACP is a popular choice for competitive shooting due to its accuracy and reliability.
Which Caliber Reigns Supreme?
Ultimately, the choice between.45 ACP and.45 GAP depends on individual preferences and needs. However, if we had to crown a supreme caliber, it would be the.45 ACP.
The.45 ACP offers excellent stopping power, moderate recoil, and a wide range of bullet weights and velocities. Its proven track record and widespread adoption make it a popular choice for self-defense, law enforcement, and competitive shooting.
That being said, the.45 GAP is still a formidable caliber that offers excellent performance and reliability. Its shorter overall length makes it more suitable for compact pistols, and its lighter bullet weight reduces recoil.
