Had a "scared myself" happen the other day, too... Took a revolver out of the range bag (ergo, not my carry piece) and went to load it, only to discover it was already loaded. Apparently I'd loaded it sometime back and never unloaded it. Gave me a cold sweat, I'll tell you!
Safe gun handling is a Good Thing (tm)!
Rule #1, all guns are loaded, all the time!
