It’s called accuracy.
If you are up a tree 8’ above the crockagator, then with an accurate pistol you pop him between the eyes.
I’ve put lots of alligators to rest with a .22 mag. Size does not matter. Their brain pan is very small.
The point was that small caliber pistols, or is it all pistols are outlawed in Australia.
Perhaps.
But for him to walk out, he’d have to get down from the tree, wouldn’t he?
Any pistol might be problematic for a man on foot faced with a charging 20 foot crocodile.
I think I’d want a 50 caliber machine gun. :)
