i'm toying with the idea of getting a western style single action revolver in 45 colt and have some questions i hope someone familiar with them can answer. are all the newer revolvers able to handle higher pressures from more modern loads or are there gonna be makes/models that are restricted to lighter cowboy action loads? also, i was just browsing rugers website and looking at what they offer and the only difference i could see between most of their models (bisley vs sass vs a standard stainless model) was the hammer. what advantages/disadvantages do different hammer styles have? i appreciate any direction and comments y'all have. thanks!
