The .357 is just a fast 9mm

Out of similarly sized weapons and similar barrel lengths... the bullets actually travel at nearly the EXACT same speed. As mentioned above, we all KNOW how much more usefull that .002 inches is ;)

There was a great comparison of the MK-9 and a S&W 2-inch snub. There was NO difference in average bullet speed. The MK-9 is smaller, and holds more rounds too... do the math.

Can we PLEASE leave the military use of the .45 and 9 mm out of this debate. Why do military forces want .45s? Because they are limited to FMJ and thus lose the advantage of state of the art bullet design (except the .45 Super used in small quantities by SEALs). Next, when they are authorized to use hollowpoints (against terrorist forces) they are usually using suppressed weapons. Let's see: subsonic 230 gr .45 HP vs. subsonic 147 gr 9 mm HP? Not much debate there.

The military use of a .45 is utterly distinct from the civilian use. Don't try to interchange the two.
 
Ahhh...perhaps somebody's been in the loco weed again?

The limited case capacity of the 9mm limits the9mm to light bullets (125 grains or less), I routinely fire 160 grain bullets from ,357 Magnums at 1400_ feet per second.
I was about yo say "try that in your 9mm" but you probably would rather heep it in one piece.
Actually, the 9mm is a good cartridge, In my SIG P210 it gives outstanding accuracy.
 
The 9x19 and 357 SIG both use .3525 to .3555 bullets. Not all 9mm bullet shapes work well in the necked case though; why most ammo companies use a different bullet just for the 357SIG.

The idea is a necked down 40; the actual cases are very different inside.

Speer 9mm 124 +P Gold Dot, in gel after cloth: 20.25/.54

Speer 357 SIG 125 Gold Dot, same, 19.05/.54

Speer 40SW 155 Gold Dot, same, 18/.57

Speer 45 200 +P Gold Dot, same, 18.8/.55

(FBI gel stats)

Whoopee! Energy is different, the size of the holes are pretty close.

Not much difference between the CorBon 115/9, 125/357, 135/40, 165/45 either.

What's my point? Beats me. :)

One thing I haven't seen mentioned yet: .357 Magnums don't have to worry about feed ramps. This gives you all sorts of freedom for what to do with the jacket, which means all that extra energy can be transferred to the target more efficiently.

And a minor correction, Will: We kept the rest of NATO from speaking Russian. If anything, they owe us even more for that.

Ben,

You bring up a very important point.

The .357 Magnum has the chamber seperate from the barrel. Hence, a 2 inch barrel in a revolver equals about a 4 inch barrel in an auto.

In comparable barrel lengths, particularly in compact guns, the .357 Magnum and the 9mm are VERY comparable in velocity.
Once you get to longer barrel lengths and heavier bullets. the .357 Mag pulls ahead.
But, comparing, say a Glock 19 to a .357 Magnum snubby: the Glock 19 is lighter, holds more than twice the firepower, has half the muzzle flash, WAY less recoil, and ballistically it will perform the same.

The .357 Mag out of the short barrel certainly has an impressive report and a scary muzzle flash, and painful recoil to make you think it is doing a lot of damage when it is not that impressive.
