I love shooting .357. GP100, SP101, Blackhawk, Vaquero, Smith Model 28, Marlin and Rossi Levers. Generally prefer the heavier 158 grain loadings. If I only could have one caliber, or even one gun, it would be a .357. For me the single most useful caliber, bar none. I have some K-frame Smiths but they are all .38s.
