I posted my results of trying 1 x .38 Special, 2 x .38 Special +P, and 4 x .357 magnum after a shakedown cruise in my then-new 640 Pro.

Several of the brands had the gurus' approval, but my performance with them didn't live up to the stats, including GDHP 135gr hp -- it was the middle performer of the seven.

The one I shot best at 7 yards was Barnes 140gr lead-free hp .357 magnums -- great groups in slow fire and even tighter groups in rapid fire. A distant second and the easiest magnum to shoot, low and left but still lethal, came the Remington Golden Saber 125gr (I think, might have been 135gr) hp .357 magnums.

I carry the one that performs best for me. Just seems logical.
