It was noted that had the M58 been made in a 41 Special round or even the 44 special, it made have fared better. Please remember that in 1964 when the M58 was introduced, one could get the m21 M&P 44 special as they languished on the shelfs or even better a 4" M24 with adjustable sights or a special order M25 in 45 Colt if a big bore N frame service handgun was wanted. The M58 was an attempt by S&W to breath some life into the N frame line with a new caliber. A 357 M20 would have fared better at the time. In the mid 60's, the m15 and M19 were ruling the roost for police revolvers, a position they held until the switch to auto loaders. With that said, I love the 41 Magnum as a big bore do it all round. Bob!
