Yeah, if I was looking for a .45 I would get a revolver.
Hattie you made some incorrect assumptions, IMHO.
The .45 isn't the "largest gun" to the fight. It doesn't compare to the .357 or 44 magnum so leaping to the Desert Eagle is kind of rediculous.
The .45 has superior peneterating power it's the perfect intermediate size. It won't glance off like the smaller caliber rounds can and it's not as heavy to wield as the larger caliber weapons.
Tell your friend to look at a Kimber, I really like them. And use spell check sometimes
