Briefly: I know of no local, state, or federal laws that limit how many guns you can own, as long as you can legally own guns.
Correct me if I am wrong, please.
People are often shocked at the number of guns people own. According to the 2015 National Firearms Survey (NFS), the average household with any guns has 8. I’ve written before about how easy it is for a normal gun owning individual or household to accumulate an “arsenal” based on different types of guns and different types of shooting. To say nothing of people who are collectors.
The NFS also reported that 3% of “super-gun owners” own 50% of the American civilian arsenal. After writing a story about this on the Michael Bloomberg funded gun newsadvocacy outlet The Trace, Lois Beckett appeared on NPR and made clear that we should not be fearful of these Gun Super-Owners. Robert Siegel asked her, “Is there any evidence that being a super-owner is linked to increased gun violence, whether of suicide or homicide?” She answered, “No, there’s no evidence of that,” and even allowed for the possibility that super-owners “might be a lot safer.”
3% of Americans would be about 10% of gun owning individuals. If they own half of all guns, then probably 20% of gun owning individuals own 80% of all guns, which follows the 80/20 rule that 80% of something is dominated by the 20% most interested. Plus or minus whatever percentage.
