I’ve had a console safe for a few years. There’s rarely a gun in it, but there has been on one or two occasions. It’s a solid steel locking box with four digit combo that replaces the liner of your center console while still using the stock lid. From the outside it looks exactly like an oem console. It’s a “buy me some time and make it difficult for them” add on.
It’s solid, well made, and I like it a lot. Cost ~ $250.00 if I recall correctly?
Looks like this:
I bought a few metal cases that are used for air travel. They have either a key or 4 digit lock with a stainless steel cable. They would delay a theft a few minutes. They would keep a kid safe if the kid was in your car. Not super impressive. When moving a gun around the car the first rule is to keep a towel. Or jacket or cloth bag so the gun is not seen.
My favorite is a dewalt tool bag. Can work as a mini range bag with pistol and a few mags and hearing protection and glasses. But i keep that on the floor in the back seat and use the bag to get the gun to the trunk. I lock the metal box to the trunk hinge.
You can lock the box to under the seat frame as well.
Remember this is a short term storage deal when needed. Its not super secure. But it beats leaving the gun in a glovebox or console.
When I had my last job that required a gun. I had a 12 inch length of pretty heavy chain padlocked to the seat frame. I had a second heavy padlock with heat shrink to protect the trigger guard or frame of a revolver. This was way more serious. But my employer required a way to secure a duty gun that was much more secure. If you can deal with that .. I suggest the chain. Its a much better way to keep your gun. A glock with a polymer trigger guard may require a cable to go thru the magwell to be secure.
I don't like keeping a gun in a vehicle for the most part, but understand the people that can't carry at work, but want to be armed to and from. I would not use anything cabled, especially those tiny 1/8" cables that usually come with small lock boxes.
Get a strong box (the thicker steel the better) and bolt it in the rear (trunk if you have one) of your vehicle.
