My though is leave my house with it in a case get in the car put it in the safe and have a nice drive to work. Holster up at work and do the opposite when on my way home.
Not sure what you mean by "a case". If you live inside a school zone then you'll need to keep your handgun in a fully enclosed, locked container until you have left the school zone. If you don't live in a school zone, then you can walk out of your house holstered up and to your car where you can then put the firearm in the safe for your drive to work.
Other than that, sounds like an excellent plan. Enjoy and stay safe.
Oh, and don't upholster while driving, it makes for strange looking furniture. :lol:
