premise??
So IF we were "gun nuts" AND did try to answer it - "unknown"..."because so far the number of guns doesn't seem to matter much".
BTW I do have guns for self-defense purposes, though they are most often used for recreation too.

"But seeing that we have around 300 million already here in the United States, and gun violence tends to increase as the number of guns in the country goes up, its just a question Id like these people to answer."
So, my question to gun nuts is simple, How many guns is enough to keep us safe?

Per the FBI background checks, the number of guns has been steadily climbing since at least 1999, while gun violence has been steadily decreasing since the 90s {I'd wager there are more like 400 million+ guns - its been "300 million" for WAY too long when there are now 20 million+ background checks per year!!}:
"Between 1993 and 2000, the gun homicide rate dropped by nearly half, from 7.0 homicides to 3.8 homicides per 100,000 people. Since then, the gun homicide rate has remained relatively flat. From 2009 to 2014, the most recent year data are available, the number of gun homicides has hovered around 11,000 and 12,000 per year"
...
"The rate of nonfatal gun victimizations declined in a similar way to the gun death rate, with a large drop in the 1990s 63% between 1993 and 2000. The decline since then has been more uneven. In 2014, there were 174.8 nonfatal violent gun victimizations per 100,000 people ages 12 and older."
...
"while the gun suicide rate has declined overall since 1993, in recent years it has risen, from 6.3 per 100,000 people in 2010 to 6.7 in 2014."
