Welcome to Handgunhunt.com!
you will get a lot of advice here, not all is perfect for you, so pick and choose carefully. Especially, listen to the guys that have tghe real experience, not "what they think should do fine."
just MHO.
Don't know who that is directed at.....
Anyhow, Tamer grips are a great addition and will improve shootability in whatever caliber you choose, particularly with the heavier kicking calibers like the .454. I have two custom SRHs -- one in .475 Linebaugh and one in .500 Linebaugh, and the Tamers make them both much more comfortable to shoot (well, the .500 still isn't really comfortable, but more or less shootable because of the Tamers).
