Yes, but I had to rule it out because each time I entered or left the vehicle I’d have to draw or holster the firearm, and doing it while still seated comes back to the original problem. There are few places nowadays that don’t have cameras, and I always assume they’re there even if I don’t spot them. The act of drawing or holstering can be considered threatening, especially in a prison parking lot or near a courthouse.
When I disarm at one of those places, I remove the entire holster and put it in a lockbox bolted to the floor in the back seat of my pickup so it doesn’t look like a firearm per se. Even if recognized, it’s still holstered and not presented at the ready. Same with putting it back in my pocket. I also let both the prison management and the courthouse police officers know I do this, but there’s a lot of turnover in those jobs and you never know who’s on duty.
With an ankle holster, I can draw it inside the vehicle and lock it in a lockbox I keep under the front seat without bringing it out of the foot well, or in a safe like @Festus showed.
That’s inexpensive enough to not get burned too bad if it doesn’t work out. Thanks.
