Yes, a shotgun. You can apologize to your husband afterward.

Anyway, he doesn’t sound like the guy who is going to protect you.

There are some non-lethal shotgun rounds, like rubber bullets, a net which deploys from a shot shell, and even a nasty colored smelling ball round.

Of course there is always 'spray foam', but you have to pressurize the cans of foam to a higher than common pressure to get the stuff to shoot a couple of yards.

With a stock cuff, the shotgun could carry a few 'back up' rounds of semi-precious metals in varying sizes and accelerant capacity.
