A compact 9mm pistol is a semi-automatic handgun that fires the 9mm Parabellum cartridge. It is typically smaller and lighter than a full-size 9mm pistol, making it easier to conceal and carry. Compact 9mm pistols are popular for self-defense, as they offer a good balance of firepower and concealability. Some of the most popular compact 9mm pistols include the Glock 19, the Smith & Wesson M&P Shield, and the Sig Sauer P365.
Compact 9mm pistols offer several advantages over other types of handguns. First, they are relatively easy to shoot, even for beginners. The 9mm cartridge is a relatively low-recoiling round, and the compact size of the pistol makes it easy to control. Second, compact 9mm pistols are very concealable. They can be easily hidden under a jacket or in a purse, making them ideal for self-defense. Third, compact 9mm pistols are relatively affordable. They are typically less expensive than full-size 9mm pistols, making them a good option for budget-minded shooters.
