That being said, you still treat all guns as loaded, and check to make sure before use.
Oh, absolutely! And here’s another point—why do people who transport guns to the range use the same bag as carry-ons? Do they not realize that if that bag gets a “hit” on a secondary inspection even if there’s no gun inside they’ve just opened themselves up for a world of pain? C’mon, folks—CHECK those bags before you pack—better yet, get a SECOND bag so you don’t do this kind of thing!
