👉 The Harvey Weapon, also known as the Harvey Barrel or Harvey Gun, is a compact and versatile handgun designed by American engineer Harvey M. Harvey in the early 20th century. It features a unique, cylindrical barrel that is significantly shorter than traditional firearms, making it easier to conceal and carry while maintaining a reasonable stopping power. The weapon typically uses a 9mm cartridge, allowing for effective self-defense in close-quarters combat. Harvey's design emphasizes portability and concealability, making it a popular choice for law enforcement, military, and civilian use. Its compact size and lightweight construction contribute to its effectiveness in various tactical scenarios.
