A gun holster is a device used to securely hold a firearm, making it easily accessible for the user. Holsters come in various styles, including inside-the-waistband (IWB), outside-the-waistband (OWB), and shoulder holsters, each designed for different carrying preferences and situations. They are typically made from materials like leather, nylon, or Kydex, providing both comfort and durability. Holsters are essential for safe firearm storage and transportation, as they help prevent accidental discharges and keep the weapon secure. Many holsters also feature retention systems, which ensure that the firearm remains in place until the user intentionally draws it. Proper holster selection is important for both safety and ease of use.
