When shopping for a car gun safe, the most important things to consider are whether you're more worried about security or accessibility, and whether you're looking for a permanent car fixture or something that's easily moveable.
If you're just looking for a safe way to transport your weapon to the gun range or a way to secure your gun in your luggage while traveling, you'll want something smaller and lightweight, with a simple lock or code. But if you'd rather have a permanent car fixture that gives you quick access to your gun for self-defense, you can invest in something bulkier, with easy-open options like a biometric scanner.
