Although this does look very silly to you and I, it's actually a very feasible idea.
You gotta be kiddin' me.
Try it. Go ahead, go out to the range and shoot a pistol holding it Hollywierd-style, and see how well you do.
LSW someitmyes watched that Dick Van Dyke show where he's the ME or coroner or whatever and is solvcing all these murders the cops can't solve whatever it's called, and in one episode, they suspected a cop was the perp. IIRC, it was allegedly an accidental shooting, but they thought he did it on purpose, so th ehwoel hting centered on whether he was your average "barely-know-how-to-pull-the-trigger" cop or whetehr he was that rare cop who knows something about shooting.
He had been transferred to working at the PD range, so Dr. Van Dyke went to visit him, where he observed the suspect shooting his model 92 with extended mag well, match trigger, and whatever other rooney stuff is available for Berettas, and asks "Can I try?" claiming he's never fired a pistol, despite having worked for the PD for decades, and his son is a Detective LT working on his law degree, but never mind...
Dick takes the pistol and proceeds to "aim" home-boy style. Policeman says "What the h3!! are you doing!?"
"Well, I see it in movies and it looks cool."
"<shrug> It's your funeral..."
BANG! Bullet goes ricocheting off of walls and ceiling, and DVD is holding a VERY sore wrist and using language you don't normally picture Rob Petrey using...
OK, yes, there are some situations where you might want to angle your pistol. But holding it horizontally is, pardon the expression, for the Birds.
Oh, yes, I note that
else has noted it, so I will observe that the Chief of Police in Norfolk or some other town in Virginia saw a printout of this page and raised cain over it, getting the city council into quite a stew and making all concerned look like utter @$$e$ when it was revealed to be a joke.
Then again, see my .sig...
