Well, here's how one city defines the problem:
The Washington Post reported on February 27 of this year that in 2019, Washington, D.C., Police took 116 homemade, unserialized guns "off the streets", and that such firearms have been used in three homicides there in recent years.
Let's be honest: If you're unqualified to buy a gun legally, building your own would be a very attractive alternative...and apparently, some people do just that.
