Great advice...there is nothing quite like an original pre 1900 Colt Single Action. The sound of it being cocked has never been reproduced by any of the new crop of single actions. The balance, the weight, the natural feel in the hand, the roll of recoil all imparts a level of confidence in the shooter that can only be equaled in some measure by the Colt M1911 45 ACP.
For full on shooting strength and utility the Ruger Vaquero is unequaled...albeit heavy in smaller calibers. There is no way you will ever wear out a Ruger running 357/38 through it.
