15 Meters?

However, I'm looking for a VERY hard-hitting, high-caliber, high-velocity handgun for the fairest price, and most affordable ammunition. Versatility is good. Light-weight(lightER weight) is good, heavy recoil is not really the primary concern, as follow-up shots really don't need to be lightning quick or at more than 15 meters, but being able to handle the gun with one hand(if neccesary) is desireable, as well as not needing to tote it around on a sling or a pack mule.
Brown bears will OFTEN make a false charge, which generally stops at about 6 or 7 meters. No way to tell if a charge is real or false outside of that range, so 10-15 meters is not likely to pass muster as a DLP (Defense of Life or Property) shooting in these parts. Alaska State Troopers or Alaska Dept of Fish & Game investigate all such shootings. I don't know about the areas you frequent, though.
I carry a 454 Casull Super Redhawk 7.5" because I like Rugers better than Smiths (because of their strength and internal lockwork). My friend keeps a 500 S&W 4" for bear protection. He carried a Smith on the job for decades and trusts the maker.
If Ruger made a 500 Bill (my name for an extended 500 S&W cartridge, which would, of course, require a stretched-frame Super Redhawk) I would opt for it. I believe in big bullets and deep penetration on bears. Hard cast and large, flat meplat.
Typical energy levels for comparison purposes (source: Wikipedia)
ft lbs cartridge
1,000 .44 Mag
1,200 45 Colt (Ruger and T/C only)
1,500 .50 AE
1,300 480 Ruger
1,800 .475 Linebaugh (same bullet as 480 Ruger, longer cartridge)
1,900 .454 Casull
2,400 .460 SW
2,600 .500 SW
and the .500 can throw a MUCH bigger bullet.
But, in bear country, I prefer pepper spray as my second line of defense and the Ruger as the third. (Good woodscraft being the first line of defense.) If only one of the two tools, it is the spray. Spray has a MUCH better track record of keeping humans unharmed in bear-human encounters than firearms of any type. You also blew a big hole in (or ruined) a nice hike or fishing trip if you have to shoot a bear, whether you killed it or not.
If you wound a bear with a firearm, you have left a danger for humans who follow behind you. If you run off a bear with pepper spray, you have left a bear more likely to be human-averse, thereby making the woods actually safer (once the spray's effects have worn off the bear's senses of smell and sight). You should report either encounter, but are legally required (again, in Alaska) to report it if you shoot the bear.
On your other thoughts:

Big bullets hit hardest. Cross-sectional area is important and momentum is more significant than energy (in my opinion).
In these parts, 500 S&W ammunition runs around $3 each. Reloading cuts that cost to less than a quarter of that. My Freedom Arms 454 cost the same as my friend's 500 Smith, a bit over $1,000. I got my .454 Super Redhawk for an even $500 (new from Wal-Mart - unused but showcase abused and WalMart reneged on their promise to fix the broken rear sight, but I held up my end of the purchase anyway).
I would love to have a 480 Ruger 5-shot 7.5", but Ruger never built any in that configuration.
I hope my ramblings and opinions help inform your thoughts.
Good luck.
Consider getting a reloading setup.
