I mean honestly, how is that even remotely comparible to my scenario?Easy way to settle this, you keep a gun holstered with the saftey on and i'll come rushing at you with a Katana from 10ft away. Then you'll see who gets killed quicker.
And yes tests have been done. I think the assailant has to be something like 50ft away before you could reliably draw a gun and stop the knife/sword weilding attacker.

Lets go weapons jousting y'all!
