Well I have the 454 in the 8 3/8" barrel, and while I see written that there a 50-50 proposition, I guess I got lucky with mine. It shoots better than I can hold in most cases. The only drawback, if it could be called that, is the price of factory ammo.
I handload all of mine so it's a wash. I was given mine by a close friend, and have had a great time with it over the past 6 or so years I have had it. I have loaded it from mild to wild and much prefer the middle ground stuff to the top shelf loads. The revolver has held up fine with no issues. The heaviest bullets I load are only 325grs, and I don't run them over 1650fps most of the time. I simply don't feel that there is anything here in TX which this won't put on the ground.
I cannot say how the 41's shoot or hold up, but I love the caliber, and if I didn't already have one in the Ruger Redhawk I might be swayed to look into the Taurus.
If you do get one, and your a caster, I highly suggest you look into the MP molds and see if there are still any of the 41 #258 Keith molds available. I purchased one in the solid and it is an awesome bullet. The first load I pulled out and loaded shot right at 2" at 50yds and would have done better but I had to hold over to try and keep from blowing the side out of my bucket trap. Had I adjusted the sights I could have easily have had a 1" or closer group from the load.
