It was from the Performance Center.
I do have a Model 657 in .41 magnum. That is a very nice N-frame. Its actually a little heavier than the corresponding 629 since there is a little more metal in the barrel wall, the .41 actually being a .410" diameter and the .44 actually being .429". I load the .41 up with Cast Performance 265 gr hard cast lead gas check bullets. Its not exactly the .44 mag, but its damn close.
