I believe most DV situations already require you to surrender your weapons. Check with each county or state to see if I am correct. I asked my local LEO's who said yes. I do know this first hand.

A gentleman I dated years ago was 'accused' of DV from his ex-wife. Until the case was settled, he was not allowed to posses them or go hunting. My ex-husband had a restraining order against him. I thought it was removed, but I learned that when the divorce was final, it actually went permanent. He cannot possess/own a gun or purchase one. He is in Florida but that also goes for Colorado. I have to remove the restraining order before he can own/purchase a gun.

I think you will find there are rules/laws in place already regarding DV situations. They are the MOST volatile out there.
