There's a list of "rules" that goes around periodically that includes this:
_F -- The average response time of a 911 call is 23 minutes; the
response time of a .357 magnum is 1400 feet per second._
I've seen this list before and it continues to bug me as an engineer
geek. The average gunfight takes place at a range of 3 yards. thus
response time for the .357 would be 9/1400 or .00643 seconds.
The rest of the story is the "rule of 3's", which suggests the typical gunfight takes
place at an average distance of 3 yards, involves firing 3 shots, and is
over in 3 seconds one way or another. Thus it would be fair as well to
say the response time of whatever gun you have to hand would be about 3
That video of the home invasion in Detroit in which the homeowner
happened to have a rusty Hi Point carbine showed 2 encounters with the
thugs, each involving 1 to 3 shots in quick succession. 3 thugs are
shown kicking open the door and entering the house. A couple of seconds
later you hear 1 or 2 shots and all 3 come flying out the door their
feet barely touching the ground. One of them drops his gun, comes back
to pick it up, then goes back in to the house. 1 or 2 more shots and out
the door he flies this time not stopping.
That woman needs to get some
range time in with that gun as no one seems to have been hit. Eventually
the cops showed up.
