Oh, that is SWEET! I love the ultra-short barrel .460.500 models because even with almost no barrel they still deliver astounding brute power!
The .460 is the more versatile since it can also shoot .45 Colt, and .454 Casull, and .454 Casull tends to run about $10 less expensive per box than .460 S&W.
You can also have the cylinder cut for Moon clips and then it will take .45 ACP, .45 Super, and .460 Rowland!
