Why dont you look at the ballistics on both guns. the 357 is much hotter. knock down power is what you want. If you want the badest semi you can get go for the 10mm 690 foot pounds of energy at 25 ft. can you say dead.
"Knock down power" is a farse perpetuated by bad gun magazines. A full power 10mm is quite a cartridge, but good luck finding ammo for cheap. If you can't practice with it, you can't hit something with it, and if you can't hit something with it, it's useless.
The fact of the matter is, virtually all handgun cartridges are "weak", relatively speaking. If 9mm is all you can handle, then go with it. I have a .357 magnum, .45, .40, 9mm, etc etc... I still use my 9mm as my primary go-to gun. I can shoot fastest and most accurate with it. I have confidence in my ammo, my gun, and my ability. That's what counts. You need to hit your target. Winchester Ranger-T 9mm 127gr +P+ ammunition has some of the best real-life street record out there for handgun ammunition.

Besides... ft-lbs isn't a measure of energy... force, yes... energy, no.
No, ft-lbs is a measure of energy. Pounds is a measure of force.
F = ma = mg
m is mass, measured in slugs.
g is gravity, measured in ft/sec/sec
F is force, measured in pounds, or slug-ft/sec/sec if you wish.
E = Fs
F is force, measured in pounds
s is distance, measured in feet
E is energy, measured in lbs-ft or ft-lbs, whatever you prefer (it does make a difference with vectors)
You're probably thinking of Joules, which is the metric measurement of energy, which is just N-m.

I read about a lot of feed problems when the FBI went to 10mm in the early 90's. I assume you own one KLS? Any problems? Since you are punching paper the availability of 10mm might be a pain. You gotta love those cheap 100rd white boxes at walmart... I know they have .45, not sure about .357sig or 10mm. You can't beat 100rds of 9mm for under $10!
Feed problems? Try women and small statured men not being able to handle a full load 10mm. This would cause flinching, poor control, and limp wristing. The round was too powerful and the FBI didn't want to spend money on training, so Smith & Wesson made the .40S&W, a downloaded 10mm essentially.
10mm is a lot of fun, I've shot it. It's a great hunting cartridge and if you have the right ammo and are willing to train with it, a good defensive (offensive?) pistol. But it's expensive and virtually non-existent, except in Glocks and a couple other spread out there.

Anyone have any experience with .40 cal? I like it because it has more power than a 9mm, but not quite as heavy as a .45. Anyone...?]/quote]
Yes, I have a Glock 23 in .40S&W. In all reality, in a full power, good hollowpoint, the difference in energy and results in a 9mm, .40, and .45 load is NEGLIGIBLE. In FMJ, it is a big difference though. My Glock 23 definitely has more perceived/felt recoil than my 1911 and my SIG 9mm. The only thing that has more recoil than it is my .357 Magnum in a full power load. Now THAT is snappy

after shooting both back to back I feel like less of a man
Why? Recoil is fun, but recommending cartridges because it's "manly" is never a good idea. More people have been killed with the "girly" .22LR than any cartridge combined (discounting warfare).
By the way, way cool that you have an NFA Uzi. I'm jealous.
