I agree it isn’t the reason that domestic homicides are happening but “easiest or efficient way to murder” does matter - especially if you are the one being targeted.Using firearms in domestic violence is probably the easiest or efficient way to murder, but let's not pretend that guns are the reason why domestic homicides are happening. If someone wanted to murder, there are at least 10 other viable methods to do so.
The flower girl at our wedding would most likely not have been alive if her father had a gun - when drunk he tried to strangle her mother, my friend, when she was 6 months pregnant and although she passed out the whole struggle took enough time that some sanity managed to return so he didn’t complete the murder of them both.
It is similar with suicide - guns make very permanent what may have been a very transient thought.
