Recently, we received an email from one of our avid readers here at Best Self Defense Weapons. In that email, he asked this particular question: “What is the difference between a .45 ACP and .45 Colt?”
.45 ACP and .45 Colt Descriptions
The term “ACP” stands for “Automatic Colt Pistol”. The .45 ACP is also known as the “.45 Auto” which was designed specifically for the M1911 semi-automatic pistol. Currently, it is the most commonly used type of ammunition for .45 caliber handguns.
On the other hand, the .45 Colt is commonly referred to as the “.45 Long Colt” or “.45 LC” (which is an incorrect term according to Shideler’s Official Gun Digest Book of Guns & Prices but it should be noted that the website of Colt still used the term “Long Colt”). The commonly accepted reason why the adjective “long” was added to the name of this type of ammo is to put emphasis to the differing size of the .45 ACP and .45 Colt (wherein the latter has longer shell).
Different Advantages of .45 ACP and .45 Colt
These two types of ammo differ in terms of performance. The .45 Colt was originally designed to utilize black powder while the .45 ACP is based on a smokeless powder. Considering the .45 Colt is the longer between the two, it is capable of packing more gunpowder which lets it provide more firepower. However, this also makes it give off more recoil than the standard .45 ACP.
In hunting, the .45 Colt is more preferred because of its higher power and ability to cover a longer distance. In self defense, the .45 ACP is more advisable since it packs a lesser recoil, provides less injury and offers more accuracy. But, if your intent is to give off more damage, then you might as well use the .45 Colt if your handgun can hold it.
