Info by Caliber and some other data points

I decided to lay this out there for anyone who is interested.
I've compiled (not a difficult task, just go to wikipedia) a listing of the speed and initial impact force (theoretical, based on F=MA) of the most popular handgun calibers out there for concealed carry.

Caliber               Ft/s              MPH              Sonic             Ft/Lbs
0.25                   900               614                Sub                  63
0.22                 1080               736                Sub                104
0.32                   925               631                Sub                123
0.380               1000               682                Sub                200
0.38                   980               668                Sub                235
0.45                 1060               723                Sub                412
9mm                 1300               886             Super                420
0.40                  1190               811             Super                424
0.357                1600             1091             Super                710

The "most" important number on this list is the "Ft/Lbs" of force at the end. That means how hard does this thing hits. I say this is a theortical number, basically because in the real world if you were hit with 710 lbs of force, for instance, you'd explode. Basically, take a 710lb weight, and drop in on your chest from a height of 1 foot... yeah, ouch time.

For those people who say that a .40 cal is world's better than a 9mm... check the numbers, you'd be wrong. It's a little better, but not much. The .45 is on par with the 9mm and .40, but it's a much larger round, so there's more hole produced, so, bigger wound.

However, as I have stated, the .357 magnum is the ultimate in hand gun calibers.

Just a little info for you so you can determine which caliber you'd like to start looking at.
