Sorry I am late to this topic. I have a fair bit of experience with this, both good and what I will be generous to myself and call "educational."
I have a vertical safe from a company called Aegis, long since out of business. Finally (maybe the patents ran out??) another company is making a very similar design. Not inexpensive, but neither are the guns I carry, and you can't put a price on the life of an innocent person - especially a police officer - who might get killed with MY stolen gun.
Here is an Amazon link:
Quick, simple access and removable to swap between vehicles by purchasing an additional mounting bracket. Also leaves room for other things in the console. Best thing is the system that pulls the firearm up out of the safe when it is opened. This allows the safe to be very narrow, leaving that additional room in the console.
Now for the "educational" part...
I initially had this on my 2003 Super Duty, in which I simply screwed the mounting bracket through the bottom of the console and into the floor pan. Totaled the SD and bought my 2012 Expy and attempted the same thing. Doh! The bottom of the console is well above the floor pan, leaving plenty of room for several electronic modules, including the Bluetooth/SYNC module and the module that controls the rear heated seats. Mounted the safe with the same screws and both my phone and rear heated seats suddenly stopped working!!
Several hundred dollars worth of online-junkyard parts later, things were working again but not 100%. Discovered those modules (SYNC anyhow) are VIN-matched to the vehicle, requiring a trip to the dealer for reprogramming.
CAVEAT: This is in a 2012 EL Limited, which has plenty of depth to accommodate the vertical design. Not sure if newer models are similar in that regard.
Hope this is helpful to someone.
