Many many years ago I was crazy with worrying about going above and beyond in staying "compliant" with mass law.I guess we are going to jail. How do you intend on taking me out of my truck thus not having my guns under my direct control?
I suppose I could zip tie the zippers.
On bolt action rifles I'd put the bolt in a seperate locked case from the rifle for transport.
Handguns I would put in seperate hard plastic cases and cable lock the gun through the barrel.
Pump action shotguns I'd put a cable lock through the action.....then in a locked case.
Break action shotguns id disassemble for transport.
I did all this for a 15 minutes drive to the club. One day I realized that I was spending upwards of 45 minutes to an hour just to get everything prepped for transport. f***ing stupid.
Then I read the transport laws and simplified my life. I know leaving them in a vehicle is subject to seperate storage laws. I don't leave the vehicle unattended on the way to the range or on the way to a hunting spot.
Non semi auto hunting guns now go im soft cases unloaded of course and go in the back seat of the truck. I just got back from "registering" my hunting guns for fort devens hunting season. Had to take the whole families hunting guns (6 total) to the dod police station at fort devens to have them fill out my dod personally owned fire arms card. All 6 guns went in soft cases in the back seat. Rolled right up to the police station like that .....cop came out and recorded serial numbers on each gun.....back in soft cases and back in the truck. No issues.
