Your original question does not require a hair splitting scientific testing program to reach the answer. When all is said and done, the majority seem to agree that the difference, if there even is a difference, is so miniscule as to be undetectable by most shooters. The barrel twist, lockup, and action differences have been cussed and discussed for many years and will be debated until the end of time. Go to the S&W forum and you'll find members similarly convinced the S&W is the "Cadillac" compared to the Colt's "Henry J".... Regardless of which brand you choose, pick good ammo, and if you do your part, that 50 pace Jackrabbit will never know the difference.
