Dropped my 1911 once right in front of a cop who claimed to have never seen one (true!). Put it in the holster, snapped the strap with the edge of my utilities top (BDUs to you civilians) in it, and when I moved, the snap opened and the piece hit the dirt! I tried to act cool, but I thought the cop was going to mess himself when he saw it falling! He was trying to get away before it hit the ground (thought it would fire)!
No harm, no foul. A scratch or two, but no damage.
