Using this pistol case is easy. First, unzip the main part of the case. Place your side arm on the soft hook - n - loop mat and use the adjustable retention strap to hold it firmly in place. You can put your magazines in the dedicated compartments. For tools or small parts, use the zippered pouches in the center divider. When closing the case, make sure all zippers are fully closed. As for maintenance, wipe the case with a dry cloth regularly to keep it clean. Avoid exposing it to extreme moisture for long periods as it might affect the moisture - resistant fabric. If there are any stains, use a mild detergent and a soft brush to clean gently. Always keep the case locked when not in use to ensure the safety of your items.
