40 S&W Handgun Information

Introduction to the 40 S&W Handgun

The 40 S&W handgun has been a popular choice among law enforcement and civilian shooters alike since its introduction in the early 1990s. Developed by Smith & Wesson and Winchester, the 40 S&W cartridge was designed to provide a compromise between the 9mm and 45 ACP rounds, offering a balance of recoil, magazine capacity, and stopping power. In this article, we will delve into the history, design, and features of the 40 S&W handgun, as well as its advantages and disadvantages.

History of the 40 S&W Handgun

The development of the 40 S&W cartridge was a response to the FBI’s need for a more effective handgun round. In the 1980s, the FBI was using the 9mm and 45 ACP rounds, but they were not satisfied with the performance of these cartridges. The 9mm was considered to be underpowered, while the 45 ACP was deemed to have too much recoil. Smith & Wesson and Winchester teamed up to create a new cartridge that would address these concerns. The result was the 40 S&W, which was introduced in 1990.

Design and Features of the 40 S&W Handgun

The 40 S&W handgun is a semi-automatic pistol that uses a double-action or safe-action trigger system. The gun is typically made of stainless steel or polymer and features a slide that reciprocates when the gun is fired. The 40 S&W cartridge is a straight-walled case with a bullet diameter of 0.40 inches and a case length of 0.85 inches. The gun is available in a variety of configurations, including full-size, compact, and subcompact models.

Comparison to Other Handgun Rounds

The 40 S&W handgun round is often compared to other popular handgun rounds, such as the 9mm and 45 ACP. Here is a comparison of the three rounds:

Cartridge	Bullet Diameter	Case Length	Muzzle Energy
40 S&W	0.40 inches	0.85 inches	350-400 ft-lbs
9mm	0.35 inches	0.75 inches	250-300 ft-lbs
45 ACP	0.45 inches	0.89 inches	400-500 ft-lbs

As can be seen from the table, the 40 S&W cartridge has a larger bullet diameter and more muzzle energy than the 9mm, but less than the 45 ACP.

In summary, the 40 S&W handgun is a popular choice among law enforcement and civilian shooters due to its moderate recoil, high magazine capacity, and effective stopping power. However, it also has some disadvantages, such as snappy recoil and less accuracy than other rounds. Shooters should carefully consider their needs and preferences before selecting a handgun, and should compare the 40 S&W to other handgun rounds to determine which is best for them.
