A holster is a type of carrying case designed to hold a firearm securely. It is typically made from materials like leather, nylon, or plastic and is worn on the body, often attached to a belt or inside a bag. Holsters come in various styles, including inside-the-waistband (IWB) and outside-the-waistband (OWB), allowing users to choose based on comfort and accessibility. Holsters serve to protect the firearm and ensure safe handling. They often feature retention systems that keep the gun in place while allowing for quick access when needed. Properly designed holsters can enhance safety and improve the overall experience for gun owners.
