A single barrel shotgun is a type of firearm designed to fire one round at a time. It features a single barrel, which means it can only hold one shell before needing to be reloaded. These shotguns are often used for hunting and sport shooting due to their simplicity and reliability. They come in various gauges, with the most common being 12 gauge and 20 gauge. Single barrel shotguns are typically lighter and easier to handle than multi-barrel shotguns. They are popular among beginners and experienced shooters alike for their straightforward operation. Many models are designed for specific purposes, such as trap shooting or waterfowl hunting, making them versatile tools for various shooting activities.
