What is the difference between compact and subcompact pistols?

Compact and subcompact pistols are both small and lightweight handguns that are designed for concealed carry or for use as a backup firearm. However, there are some differences between the two.

A compact pistol is typically a small version of a larger handgun, such as a full-size service pistol, with a shorter barrel and grip. Compact pistols are designed to be easier to conceal than their full-size counterparts while still retaining many of the same features and capabilities. They generally have a magazine capacity of around 10-15 rounds and are chambered in popular self-defense calibers like 9mm, .40 S&W, and .45 ACP. Also in the compact section of firearms you also have single and double stack modifications. Also multiple stock options with compact size barrels and slides like the Springfield XDM or the Glock 45 that has the compact slide and barrel with the full size frame. 

A subcompact pistol is even smaller and more compact than a compact pistol, with a shorter barrel and grip. They are designed to be even easier to conceal than compact pistols, and are often used as a backup gun or for deep concealment. Subcompact pistols typically have a magazine capacity of around 6-10 rounds, and are also chambered in popular self-defense calibers like 9mm, .40 S&W, and .45 ACP.

​Overall, the main difference between a compact and subcompact pistol is their size and weight, with subcompact pistols being even smaller and lighter than compact pistols. However, both types of pistols are designed for concealed carry and can be effective self-defense tools if used properly.
