45 Super makes 357 look sick by

comparison, if same wt bullet, same size and wt gun are compared, and a factor is rapidfire controlability. 125 grs, 1500 fps is nothing much, pressure wise, in a 6" barreled 1911, which is the same 9.5" OAL as is a 4" K Frame 357, and that load will bust up the K frame in 2000 rds or less.
