The compact and concealable nature of this pistol, combined with its historical significance, makes it a popular choice for many gun enthusiasts.

We will delve into its history, features, performance, and more to help you make an informed decision if you’re considering adding one to your collection or for self-defense purposes.

What is a Derringer .380?

A Derringer .380 is a small, pocket-sized pistol that gained fame in the 19th century for its use as a concealed carry weapon. It is known for its two-shot capacity and unique design, with the barrel hinged to the frame, allowing it to flip upward for loading and unloading. The .380 ACP (Automatic Colt Pistol) caliber, also known as 9mm Short, is one of the most common calibers used in Derringer pistols due to its manageable recoil and sufficient stopping power for self-defense.

History of Derringer Firearms

The origin of the term “Derringer” can be traced back to Henry Deringer, an American gunsmith who designed and manufactured the first small, single-shot pistol in the mid-19th century. The name “Derringer” became synonymous with small, concealable firearms. These pistols were often favored by gamblers, gamblers, and even ladies for their ease of concealment.

The Cobra Derringer 380

Among the many manufacturers of Derringer .380 pistols, Cobra Firearms stands out with its Cobra Derringer .380 model. Cobra Firearms has earned a reputation for producing affordable and reliable firearms, and the Cobra 380 is no exception. Let’s take a closer look at its features and specifications.


Features and Specifications

The Cobra Derringer .380 is a two-shot, hammer-fired pistol. It features a simple and compact design, with a length of just a few inches and a slim profile, making it highly concealable. The pistol is made from stainless steel, which adds to its durability and corrosion resistance.

.380 Derringer vs. Other Calibers

When it comes to choosing a Derringer pistol, one of the primary considerations is the caliber. While the .380 ACP is a popular choice for its balance of recoil and stopping power, there are other caliber options available in the Derringer platform. Let’s compare the .380 Derringer with some other common calibers:

.380 ACP vs. .22LR Derringer

The .380 ACP generally offers more stopping power compared to the .22LR, making it a preferred choice for self-defense purposes. However, the .22LR can be a suitable option for those seeking a low-recoil and low-cost ammunition for recreational shooting.

.380 ACP vs. 9mm Derringer

The 9mm caliber offers more stopping power than the .380 ACP, but it also comes with increased recoil. Some shooters may find the .380 ACP more manageable for concealed carry, while others might opt for the 9mm for its greater effectiveness in defensive situations.

Is the .380 Derringer Suitable for Self-Defense?

The suitability of the .380 Derringer for self-defense largely depends on individual preferences, proficiency, and the specific use case. While the .380 ACP may not have the stopping power of larger calibers, its compact size and ease of concealment make it a popular choice for those looking for a lightweight and easily portable firearm for personal protection.

It’s important to remember that carrying any firearm for self-defense requires proper training, practice, and understanding of the legal implications in your jurisdiction.
