The short answer is no, you cannot shoot .45 GAP ammunition in a .45 ACP firearm, and doing so could have serious consequences. While the names sound similar, and the calibers are close in size, there are crucial differences that make them incompatible. This article will delve into the specifics of these cartridges, explaining why attempting to use the wrong ammunition is dangerous and providing essential safety information.
Understanding the Differences Between .45 GAP and .45 ACP
Both .45 GAP (Glock Auto Pistol) and .45 ACP (Automatic Colt Pistol) are pistol cartridges designed for semi-automatic handguns. However, their design and dimensions differ significantly, preventing interchangeability.
Cartridge Dimensions: A Key Difference
The most critical difference lies in the cartridge case dimensions. .45 GAP cartridges are shorter and narrower than .45 ACP cartridges. This seemingly small difference prevents the .45 GAP round from properly seating in the chamber of a .45 ACP firearm, and vice versa.
| Feature | .45 ACP | .45 GAP |
|---|---|---|
| Case Length | 1.265 inches (32.13 mm) | 1.161 inches (29.5 mm) |
| Case Diameter | 0.45 inches (11.43 mm) | 0.45 inches (11.43 mm) |
| Bullet Diameter | 0.452 inches (11.48 mm) | 0.452 inches (11.48 mm) |
| Rim Diameter | 0.472 inches (11.99 mm) | 0.472 inches (11.99 mm) |

Chamber Pressure and Design
Apart from the dimensions, chamber pressure also differs. While both are relatively high-pressure cartridges, the pressures are not identical. Firing a .45 GAP round in a .45 ACP gun could result in a catastrophic malfunction, including a bulging barrel, ruptured casing, or even a burst gun. Conversely, a .45 ACP round in a .45 GAP firearm would likely fail to chamber or feed properly, leading to a misfire.
The Dangers of Using Incompatible Ammunition
Attempting to fire the wrong ammunition in any firearm is extremely dangerous and could lead to serious injury or death. Here's a breakdown of the potential risks:
- Chamber Obstruction: The .45 GAP round might partially chamber, obstructing the firearm’s mechanism. This can cause a failure to feed, a failure to extract, or potentially cause a catastrophic rupture.
- Barrel Damage: The shorter .45 GAP case could cause excessive pressure in the .45 ACP chamber, resulting in barrel damage or rupture.
- KABOOM: A catastrophic failure could lead to a "KABOOM," where the firearm ruptures, sending fragments of metal flying and causing severe injury or death.

Identifying Your Cartridge Type
Always ensure you have properly identified the caliber of your firearm before handling ammunition. Verify the markings on the firearm itself and cross-reference with your firearm's manual. Never rely on visual estimates; only use ammunition specifically designed for your gun's caliber.
- Check the Marking on the Gun: Look for clear markings on the slide or barrel of your firearm indicating its caliber (e.g., ".45 ACP" or ".45 GAP").
- Consult the Manual: If you have the original manual for your firearm, it should clearly specify the correct type of ammunition to use.
Conclusion: Safety First
Using the correct ammunition is non-negotiable when handling firearms. Never attempt to shoot .45 GAP in a .45 ACP firearm, or vice versa. Always double-check your ammunition before loading and firing any weapon. The potential consequences of using the wrong ammunition are too severe to risk. Prioritize safety and ensure you understand the fundamental differences between various calibers before handling firearms and ammunition. Remember, responsible gun ownership is paramount.
