Question

Is a sawed off shotgun a federal or state offense?

Answer 1

Both. Barrel length must be at a minimum of 18" long and overall length of 26". There may be an exception to the Gun Control Act of 1968 if the gun was manufactured and or modified prior to 1898 as an antique exception. But don't quote me on that. And you may still get hit by state law.

Answer 2

Both, as fas as California and the US go.

Answer 3

both

Answer 4

most countries a sawn off shotgun in your possession, yours or not, will get you jail time
