Recoil? Try the .45 ACP Downsizer or the Zeliska 600 N.E.
skidmark had an interesting post about the downsizer .45 ACP

He apparently has made quite a bit of pocket change because of the difficulty producing fast (or even slow) followup shots. Reportedly even the manufacturer recommends a rate of fire no greater than 5 times per day.
By his testimony, using the gun as a betting device, he has paid for the gun almost twice over (less two payouts and the cost of ammunition) because of the difficulty of 1) reloading and 2) tolerating a second shot.
read his post. It is fascinating, and he is a better writer than I am.
Despite the fact that the 45-70's brass panatela LOOKS impressive, the wisdom of putting a cartridge whose volume is greater than the volume of the barrel is questionable. It is just unsound interior ballistics. A 2" long cartridge behind a 2" long barrel just wastes space. Put the same bullet in a 1.4" cartridge and you get 30% more distance for acceleration, and a better "fill ratio" (for efficient ignition and burn) inside the cartridge. I have just described substituting the 454 Casull for the 45-70 in the same platform. I guarantee you will get more muzzle velocity with the same bullet weight (swage your lead .458" bullets down to .452") with probably less felt recoil (because the acceleration will be spread out over a longer period of time).
Then there are the Howdah and Lancaster pistols of the late nineteenth century favored for emergency defense against dangerous animals in Africa and India. And my personal (still in my head) design of a an 8" over-under side-break pistol chambered in .500 or .460 S&W. That should be sufficient for any bear in North America at close range.
The top contender for impracticality, though, has got to be the Austrian Pfeifer-Zeliska 600 Nitro Express revolver.
