True story.
My very first handgun was an Auto-Ordnance 1911 clone that I still own.
When I picked it up the first thing I did was buy a box of ammo and headed for the local sand pit.
I loaded the magazine, racked the slide, took aim, and fired.
OOOOOOUUUUUUCCCCCHHHHHHHH!!!!!!!!! Who would have known a pistol was so loud without hearing protection!
Well I was all the way out there, had my very own pistol, and no hearing protection.
What to do? Yep, I stuffed a couple of live rounds in my ears and proceded to burn through the rest of that box of ammo, save for 2 rounds that kepts my ears safe!
These days I use slightly better hearing protection, but on that day I used what was at hand!
