Introduction
Carrying a firearm is a personal decision, one laden with responsibility and a need for constant vigilance. The choices available to those seeking personal protection are numerous, but the quest for the ideal concealed carry setup often leads to a search for the perfect balance of power, size, and ease of use. For years, one cartridge stood out as a formidable contender in the world of self-defense: the .40 Smith & Wesson, or .40 S&W. While its popularity has seen some shifts in recent years, the .40 S&W remains a relevant and potent round. Paired with a well-designed single-stack pistol, it creates a compelling package for those seeking discreet yet effective protection. This article dives deep into the world of single stack pistols chambered in the .40 S&W, exploring their strengths, weaknesses, and some of the best examples available.
The .40 S&W Cartridge: A Detailed Look
The story of the .40 S&W is a tale of collaboration and adaptation. In the early nineteen nineties, the Federal Bureau of Investigation (FBI) realized their agents needed an alternative to the .38 Special and 9mm, given their limited stopping power in some cases. The FBI began testing various rounds to find the best fit for their needs. The .40 S&W was born out of a partnership between Smith & Wesson and Winchester. This collaboration sought to address the deficiencies of the 9mm while minimizing the heavier recoil associated with the .45 ACP. The goal was simple: create a round that could offer more stopping power than 9mm, with a recoil impulse manageable enough for accurate follow-up shots.
Ballistically, the .40 S&W offers a range of bullet weight options, generally between one hundred and eighty and two hundred grains. Muzzle velocities vary based on the bullet weight and specific ammunition, but generally range from nine hundred and fifty to one thousand one hundred feet per second. This translates to significant muzzle energy, making the .40 S&W capable of delivering a substantial impact on target. The .40 S&W’s relatively flat trajectory also contributed to its desirability, making it easier to achieve accurate shots at varying distances.
One of the primary advantages of the .40 S&W is its inherent stopping power. The larger bullet diameter and greater energy transfer often translate to more effective incapacitation compared to 9mm rounds, especially when considering the variety of modern defensive ammunition available. The round also offered a perceived “middle ground” between the 9mm and .45 ACP, presenting what seemed like a solution to many law enforcement agencies’ needs.
However, the .40 S&W is not without its drawbacks. The recoil is generally more significant than that of a 9mm, requiring more practice and skill to master. The higher pressure and recoil can also put more stress on a firearm’s components, leading to concerns about the longevity of certain models. Furthermore, magazine capacity is often lower than what is available in similarly sized 9mm pistols, because the cartridge itself is wider than the 9mm round.
The popularity of the .40 S&W has seen its share of peaks and valleys. During the late nineteen nineties and early two thousands, it was a dominant force in law enforcement and civilian markets. However, the pendulum has swung, and the 9mm has become the dominant round again for a multitude of reasons, including advancements in ammunition technology.
The Single-Stack Design Explained
Before we delve into specific models, understanding the nature of single-stack pistols is crucial. The term “single-stack” refers to the magazine design. In a single-stack magazine, the cartridges are arranged in a single column, one on top of the other. This contrasts with “double-stack” magazines, where the cartridges are arranged in two staggered columns, increasing capacity but also usually increasing the width of the magazine and grip.
The primary benefit of a single-stack pistol is its thin profile. This slimness makes single-stack pistols significantly more concealable than their double-stack counterparts. The narrow grip is often more comfortable for concealed carry, especially for individuals with smaller hands or those who prefer to avoid the bulk of a larger firearm. The reduced width makes them easier to conceal under various types of clothing.
However, the single-stack design has inherent trade-offs. The most notable is the lower magazine capacity. Because the cartridges are arranged in a single line, there is simply less space for rounds. A smaller magazine capacity requires more frequent reloads in a defensive situation. The single-stack design can, in some cases, also result in a wider grip, though this varies significantly from pistol to pistol depending on the design.
Exploring Notable Examples of Single Stack 40 S And W Pistols
Now, let’s examine some standout examples of single-stack pistols chambered in the .40 S&W.

Things to Consider When Choosing a Single Stack 40 S And W Pistol
When selecting a single-stack .40 S&W pistol, several factors warrant careful consideration.
The intended use is the most important factor. Is this pistol primarily for concealed carry? If so, size and weight become critical. A smaller, lighter pistol will be easier to carry all day. For home defense, the size and weight are less critical, but the pistol should be easy to handle and operate under stress. For range use, the focus shifts to accuracy, ergonomics, and overall comfort.
Grip and ergonomics are also vital. The pistol should feel comfortable in your hand. A grip that is too small or too large will hinder your ability to maintain a solid grip and control the weapon. Ensure the grip texture is appropriate for your needs – not too aggressive, which could irritate your skin, and not too smooth, which could make it difficult to maintain a secure hold.
Reliability is paramount in any self-defense firearm. Choose a pistol known for its dependability and a proven track record. Read reviews and ask experienced shooters about their experiences with different models. Properly maintain your firearm by keeping it clean and lubricated. Perform function checks before each use.
Safety features are essential. Look for a pistol with safety features like a trigger safety, a firing pin safety, and, if desired, a manual safety. These features add an extra layer of protection against accidental discharge.
