My Order would be:
1 Smith & Wesson
2 Ruger
3 Taurus
It took alot for me to buy a Smith, after what they did with the Clinton Administration, however, the 500 was something I had to have. I will also buy a Taurus 500 once Taurus starts producing them. Ruger is a work horse, not the prettiest gun by a long shot, but it never fails, and the scope mounts are integral to the frame, so they are rock solid. Grips are a personal preference, what fits me, may or may not fit you, however, there are aftermarket grips for all three guns, so you should be able to custom fit the gun to your hand. For hunting purposes, an 8" barrel is good, and longer and it becomes prohibitive in Iowa, not out west, any shorter and you lose accuracy, unless you scope it. Do you plan on putting a scope on it? Do you reload?
