Mike,
If you have not looked at a 357 Maximum you are missing a good bet. If anyone ever put lightning in a bottle this is it. There were several manufacturers when the cartridge first came out in the early 80s but most have fallen away because of the reported 'problems' with the cartridge.
The 'problems' came from guys who liked to shoot 110 and 125 grain rounds. Lots of fire at the muzzle and some erosion of the frame strap at the barrel cylinder junction. If you shoot 158 grain or heavier bullets (which it loves) this pistol is trouble free and nothing short of spectacular.
Check out Dan Wesson's contribution and then check a few reloading manuals for ballistic performance. This cartridge is truly amazing without the recoil abuse for the shooter that the larger bore cartridges produce. Don't be confused it is not a wimp but it's recoil is nothing like shooting a 44 Mag.
