You can bet your Dixie ass they will- L.C. Smiths, whether R framed or FW, pre-1913 or post 1913 mfg. go with heavy loads that belong in a Model 12 Winchester like STP goes with George Dickel. Ask any good LC Smith gunsmith, like my friend Buck Hamlin, what he thinks- the heavy recoil pad on your Smith may save your shoulder, but not the fragile wood inlettd into the locks and tang areas. Bad idea, Suh!!
