That is a different statement. It's saying abusers can be more dangerous with a weapon. It does not follow that people who own a weapon are somehow more likely to be an abuser.
To make that argument it would need to say something about what percentage of gun owners commit abuse or some kind violent crime.
You can find higher rates of domestic violence among cops for instance so maybe you could argue cops are more likely to be abusers.
My original statement was that owning a lot of guns wasn't suggestive of anything. The comment suggested there was a "correlation" with owning guns and domestic violence in response.
