Look at a Console Vault. These are built to fit inside you existing vehicle console and have a combination lock. They are designed for a surprisingly wide number of common vehicles. I have one in my Toyota van. Very large. Not perfect but it is well concealed and provides at least some feeling of security. Much better than a cable attached lock box. Sometimes I use both to separate ammo from firearms in states without concealed carry reciprocity. Look at a Ruger LCP for the most comfortable concealed carry experience. With the right pocket holster it does not print when dropped in your pants pocket and is light enough to not pull your pants down.
A Springfield Armory 9mm (Hellcat) now comes with a MANUAL safety, and loads 13-15 rounds. A perfect weapon for $600.
I would take a serious look at the SW Shield EZ in 9mm. It;s lightweight, it carrys a good punch, and it’s great for people with arthritis, easy to rack slide and easy to load magazines. I have one, about to get another for my GF.
I have some age and medical issues that make a revolver a better choice most of the time (but not always). How about you.
I never just drop a handgun in my pocket. Even with a mouse gun (NAA Sidewinder) I use a pocket holster.
I place a lockable case in a secure storage area liker a trunk. I place the weapon there prior to arrival at the place where I have inability to carry.
I like the Judge. A 410 pocket scattergun is not going to go through the next car and hit some poor kid.
With respect to those hand guns, they are both excellent. Buy them both.
