9mm is a .45 set on stun, and real men don't use stun !!!!!
I like that. A 9mm is okay, because any gun is better than none, but you better practice your double-taps. It's twice as effective as a .380 but only half as good as a .45. And .45 is the only pistol caliber used by any of the world's military that will consistently put someone down with ball ammo. As civilians we have the benefit of all the latest " magic bullets", but I don't want to bet my life that they'll perform as advertised. If the hollowpoints I use in my .45s don't expand for some reason, I know they're still going to be twice as effective as a 9mm, and four times better than a .380, that don't expand. And don't have to use a +P+ load that only tries to equal a .45.
I think the the hand-held mini-gun from
Predator is about as manly as a firearm can get.
For something that isn't man-portable I vote for the 16" guns they used to have on battleships. I think the shells weighed about a ton. One of my old platoon sergeants said that in VietNam you could see the shells going through the air and they looked like flying Volkswagens. And I heard that when they clean the barrel of the gun, they send a skinny guy up it with a mop. That gives "big-bore" a whole new meaning.
