I would have one in about 4 weeks if offered today in a 5.5 inch barrel.
Super redhawk is big, I have yet to like a taurus I have held, and have never seen a *&* in 454.
A super black hawk is sort of small for 454, but the after market makes a 5 shot 454 I think on the super blackhawk. I plan to send my 5.5 inch super black hawk out once I get around to getting the shorter barrel super black hawk in 44 mag.
I like bigger bangs. The v8s in my cars and trucks are never left stock, I like more power. Even if rarely able to experience a full throttle blast, they are awesome at the drag strip.
A 454 black hawk would be the same. Not something to shoot a lot, but something that packs a lot more bang than normal.
I think tamara had something about torque and gunpowder for a phrase for a while.
Both are good, more is better.
