Good topic! After handling firearms for 6 decades I finally had my first drop a couple weeks ago. What I’m saying is this can happen to any of us. Fortuanately I did not try to catch it, and I took my time carefully picking it back up with my finger off the trigger.
I posted about it a couple days ago:
Here’s the rest of the story. I had to disarm while out in my car. When I returned home I was standing beside my car in the concrete driveway. As I was transistioning the firearm from the car to the IWB holster on my hip a gust of wind caught the open door and it hit me.
