You need a permit in CT to buy a gun, carry a gun or even buy ammo. I worked for a few years at the gun counter for a national chain. I had two NY State Troopers, in uniform try to buy ammo in CT. I very reluctantly had to turn them down.
They responded that they had arrest powers in CT.
I said, ‘that’s what I’m trying to avoid”
Clearly unconstitutional, per Bruen.
