I have a s&w 686 and a taurus 44, my dad has a taurus66 and a gp100, the taurus 66 shoots good, but seems to have a little more play just about everywhere, with a fairly notchy, but light trigger, the bead blasted stainless also shows wear and scratches pretty easily, seems to be a "softer" steel, but smoothing the trigger and replacing the crappy long and narrow stock grips with hogue monoblocks and it feels pretty nice. I like all the revolvers, but if i was going to reccomend one it would be to save up for the 686, better trigger, better finish, feels like a single block of steel. a gun you are not happy with can cost more than just getting the one you want in the first place, because eventually you are probably going to get it anyway. they both fit in an uncle mikes #2 holster and have held up for at least 5,000 rounds of mid power 357s each with no parts breakage and both feel good and "broken in" the gp100 has about 10,000 rounds and still doesn't feel quite as smooth as it could.
p.s. pitbull ive always had a heck of a time getting any scope mount to fit correctly on a taurus alot of milling and fitting to get it bedded properly, but for close hunting a decent 1x red dot scope like an ATN ultra works nice and is fairly light, for distance I like the 1.5-4x simmons 28mm pistol scope , i have one on my 44, faily easy to shoot 6" groups at 100yds with the butt sitting on something and the scope stays 0ed through at least 100 240gr 1500fps loads, getting it bedded properly is the key if not it will loosen up especially with heavy magnum loads and will be near impossible to get sighted in.
