So basically i know nothing about this subject other than basic mechanics of a revolver. I have found information on this subject extremely hard to come by so any help is appreciated. What i need help with is just selecting a gun, and modifications to do with it. I'm not building this gun to abide by any rules. Not really a competitive type of person. Maybe in the future. So far i've selected the Ruger Blackhawk, Ruger Vaquero, and Uberti Cattleman as candidates. I have questions about each. Blackhawk- So if i understand correctly the .357 mag old model Blackhawk bored to .45 is the best gun for this? Understandable, smaller, lighter gun with Rugers great quality. But why is the old model Blackhawk better than the new model? Vaquero- This kind of relates to the last question, can the vaquero be bought in a smaller caliber like the Blackhawk and be bored out to .45? or is the frame the same size already? Also New or old model, i often see people say the new model is better but that contradicts the Blackhawk where they say old.. Cattleman- This one is simple, what exactly is weaker about the Uberti Cattleman "SAA"? Is it just the springs, and if so how often would they break? I'd be fine with buying several sets of replacement springs to have an more original looking gun. Thanks, any other help/experience is welcome!
