You live in Co you own a handgun you are not 21 Is it legal for you to transport your handgun in your vehicle when you take it to go shoot as long as it is unloaded?
If the firearm is unloaded, in a case, and locked in the trunk
or toolbox of a pickup, yes, should be legal. There is a Federal
law known as Peaceable Journey that covers this. If you do not have
a trunk or toolbox, then unloaded, and in a locked case (not the
glove box).
