Both 38 S&W and 38 Special are popular cartridges used in revolvers, but they have distinct differences that set them apart. They were both developed in the late 19th century and have been used extensively in law enforcement, self-defense, and sport shooting.

The main differences between 38 S&W and 38 Special are:

  1. Cartridge Dimensions: The 38 Special is a longer and more powerful cartridge, measuring 1.55 inches in length compared to the 1.28 inches of the 38 S&W.
  2. Pressure and Velocity: The 38 Special has a higher pressure and velocity, producing more force and energy upon firing.
  3. Bullet Weight and Design: The 38 Special has a wider variety of bullet weights and designs available, ranging from 110 grains to 200 grains, while the 38 S&W is limited to 145 and 150 grain bullets.
  4. Availability and Cost: The 38 Special is more readily available and has a wider range of options, making it more popular and affordable compared to the 38 S&W.

Despite these differences, there are also some similarities between the two cartridges, including:

  • Caliber: Both 38 S&W and 38 Special have a bullet diameter of .357 inches, making them compatible with the same barrel size.
  • Revolver Compatibility: They can both be fired from the same revolvers, although the 38 S&W requires a specific chamber and cylinder size.
