The chart above reflects the number of background checks done by the NCIS system for people wanting to buy a gun. It is the best indicator we have on the number of gun sales each month (even though it doesn't include private sale, internet sales, or most gun show sales).
Note that in most moths the checks have increased in the last three years. That means that gun sales are increasing -- even though we already had more guns than citizens. There seems to be no limit to the number of guns owned by individuals in our society.
