I have read Tom Fergusons book entitled "Modern Law Enforcement Weapons and Tactics" and probably even still have my beat up old copy somewhere. In the book, he talks extensively about the Model 58 .41Mag. He said the department received an initial shipment of about 400 revolvers, with more to come bringing the total shipment to 1000 units. Mr. Ferguson said the workmanship and quality control on quite a few M58s shipped were terrible; this included 14 being rejected outright for things like rear sights being milled off center and a .44Mag cylinder mistakenly installed in one .41 revolver.

However, he did say the M58 was one of the greatest police revolvers. I tend to agree...

RIP Sergeant Ferguson...
