.40 S&W Overview

The .40 Smith & Wesson represents a purpose-built law enforcement cartridge that found widespread civilian adoption. Developed in 1990 as a joint venture between Smith & Wesson and Winchester, it was designed to offer near-10mm Auto performance in a more manageable package. The cartridge delivers substantial power while remaining controllable in duty-sized handguns.

While many law enforcement agencies have transitioned back to 9mm, the .40 S&W maintains a dedicated following among civilian shooters who appreciate its balance of power and practical shootability. Modern ammunition developments have kept it relevant, offering enhanced performance through improved bullet design and optimized loadings. The cartridge continues to serve effectively in defensive, competitive, and duty roles.

Advantages and Disadvantages

Pros

  • More powerful than 9mm Luger
  • Good terminal performance
  • Wide selection of defensive ammunition
  • Functions in modified 9mm-sized platforms
  • Proven track record in defensive use

Cons

  • Snappier recoil than 9mm
  • Reduced magazine capacity vs 9mm
  • More expensive ammunition
  • Increased wear on lighter firearms

.40 S&W Ballistics

The .40 S&W typically achieves velocities between 950-1,200 fps with standard pressure loads, using bullets from 155-180 grains. This generates energy levels suitable for defensive use while maintaining manageable recoil in full-sized handguns.

What .40 S&W Does Best

Personal Defense

The .40 S&W excels in defensive applications, delivering substantial energy and proven terminal performance. Modern defensive ammunition provides reliable expansion and adequate penetration, while the cartridge's moderate recoil allows for good shot placement in proper defensive scenarios. The availability of quality defensive loads from major manufacturers ensures reliable performance for personal protection.

Law Enforcement

Despite recent trends toward 9mm, the .40 S&W remains effective in law enforcement roles. Its ability to perform through intermediate barriers while maintaining good accuracy makes it suitable for duty use. The cartridge's power-to-recoil ratio, while higher than 9mm, remains manageable with proper training, and its terminal performance is well-documented through extensive field use.

Competition

In competitive shooting, particularly USPSA and IDPA, the .40 S&W offers advantages in power factor calculations. While more challenging to shoot than 9mm, skilled competitors can leverage its power factor benefits while managing the increased recoil. The cartridge's widespread availability and proven reliability make it a practical choice for competition use.
