Background and History: A Look at the Origins
Nine Millimeter Luger
The nine millimeter Luger, also known as the nine by nineteen millimeter, boasts a lineage that stretches back to the late nineteenth century. Designed by Georg Luger in Germany, this cartridge quickly gained widespread adoption due to its effective combination of power and manageable recoil. The nine millimeter’s ability to fit more rounds in a magazine compared to its contemporaries, along with its relatively easy handling, contributed significantly to its early success. It also benefited from the development of reliable, semi-automatic pistols, making it a popular choice among both military and civilian users. Its adoption by the U.S. military in the late twentieth century cemented its status as a global standard, and it remains a favored choice in the modern era.
Forty Smith & Wesson
The forty Smith & Wesson, or point forty, entered the scene in the mid-1990s. Its genesis can be directly linked to the Federal Bureau of Investigation’s (FBI) desire for a cartridge that offered improved stopping power compared to the nine millimeter, while maintaining similar overall firearm size and control characteristics. This desire stemmed from the need for a caliber that would be more effective in a variety of potential engagements. The forty S&W was developed as a collaborative effort between Smith & Wesson and Winchester. It’s essentially a shortened and slightly wider version of the ten millimeter Auto, designed to fit in existing nine millimeter pistol frames with some modifications. This allowed for a transition to a more potent cartridge without a complete redesign of police departments’ handgun inventories.
Ten Millimeter Auto
The ten millimeter Auto stands apart in its history. Conceived by firearms enthusiast and designer, Jeff Cooper, and developed by Norma, this cartridge was introduced in the early 1980s. Cooper envisioned a potent handgun cartridge suitable for both self-defense and hunting purposes. The ten millimeter was designed to deliver significant power, pushing heavier bullets at impressive velocities. Initially chambered in the Bren Ten pistol, the ten millimeter promised a significant increase in power over existing pistol cartridges. However, the Bren Ten’s early production issues, combined with the cartridge’s higher recoil and the cost of ammunition, initially limited its widespread adoption.
Ballistics: A Study of Performance Metrics
Velocity and Energy
When we compare the velocity and energy of these three rounds, the ten millimeter undoubtedly leads the pack. It fires heavier bullets at higher speeds than the forty and the nine. This translates to substantial muzzle energy, providing greater potential for stopping power and a flatter trajectory over longer ranges. However, the specifics depend on the bullet weight and the load. Some commercial ten millimeter loads can produce muzzle energies exceeding seven hundred foot-pounds, while others are more modest.
The forty Smith & Wesson sits squarely in the middle ground. It offers a power boost compared to the nine millimeter, generally resulting in more muzzle energy. Its velocity and energy, again dependent on the bullet weight, usually put it comfortably between the nine millimeter and the ten millimeter. The forty is known for its good balance between power and controllability.
The nine millimeter, with its lighter bullets and lower velocities, delivers the least amount of energy. While it may not match the raw power of the other two cartridges, the nine millimeter’s effectiveness shouldn’t be underestimated. Advances in ammunition design, combined with its inherent ease of handling, have led to a resurgence in its popularity for self-defense. A wide range of nine millimeter loads exist today, from standard pressure to +P (over pressure) ammunition, providing diverse performance characteristics.
Penetration
Generally, a heavier bullet traveling at higher velocities will tend to penetrate further. In practice, factors such as bullet design also significantly affect penetration depth.
The ten millimeter, due to its higher energy, tends to offer superior penetration capabilities, and this makes it suitable for challenging defensive scenarios and for hunting. The forty S&W also demonstrates decent penetration. The nine millimeter, while not as potent, has benefited from innovative bullet designs, resulting in controlled expansion and adequate penetration in many defensive situations. The specific bullet type and load are the critical determinants of this characteristic.
Recoil: The Impact on Handling and Accuracy
Felt Recoil
The ten millimeter, with its high power, generates the most recoil among these three cartridges. The shooter will feel a sharper, more pronounced recoil impulse. The felt recoil is also influenced by the weight of the firearm; heavier pistols tend to absorb more recoil. The added recoil can make it more challenging to maintain accurate shot placement and to acquire the target again quickly after firing.
The forty S&W’s recoil is noticeably more substantial than that of the nine millimeter. It’s often described as a snappy recoil, as the shorter, wider case produces a more abrupt impulse. This means the shooter must have a firm grip and solid stance to manage recoil and maintain control.
The nine millimeter typically has the lowest recoil of the three. This, along with the cartridge’s wider availability and more affordable ammunition, contributes to its appeal for shooters of all skill levels. The reduced recoil allows for faster follow-up shots and easier target acquisition.
The size and weight of the firearm also play a significant role. A larger, heavier firearm will help to absorb more recoil than a smaller, lighter one. The grip size and ergonomics of a firearm will also have an effect on the shooter’s ability to control the firearm during recoil.
Availability, Affordability, and Firearm Choices
Ammunition Availability
The nine millimeter is the undisputed champion of ammunition availability. You can find it at virtually every gun store, sporting goods outlet, and online retailer. The sheer volume of nine millimeter ammunition produced globally keeps the price relatively low. You have a vast array of choices in bullet weights, designs, and prices to accommodate virtually every need.
The forty Smith & Wesson’s popularity has waned a bit. While still readily available, you might find it less commonly stocked than the nine millimeter. The price of forty ammunition is usually higher than nine millimeter but generally less than ten millimeter, depending on current market conditions.
The ten millimeter occupies a niche market. While ammunition is available, it’s usually more expensive, and selection is not as broad. You might need to shop around to find specific bullet weights or premium loads.
Firearm Selection
The range of firearm choices for the nine millimeter is truly exceptional. It’s chambered in countless handguns, from compact concealed carry pistols to full-size duty weapons. You will find a wide variety of manufacturers, price points, and features.
The forty Smith & Wesson’s popularity saw a decline, and this reflects in the range of firearms currently available. Nevertheless, there are still numerous options. You’ll find handguns from many major manufacturers.
The ten millimeter is available in a more limited range of handguns. However, the choices do include several excellent models, and some manufacturers have made a resurgence in the last few years.
