@Neophyte who was your Friend - Wyatt Earp? Seriously, That’s some very rare “real life experience” and someone that has real credibility vs just another opinion…I would listen and pay attention to that Man.
From what I’ve read about the origin & history of the .41 mag and model 58 - it was close to a perfect handgun round for Police and had a balistic advantage over other common Police Revolvers used by Law Enforcement ( .38spl and .357). It’s downfall was that most Police Officers could Not handle it’s recoil and could Not shoot it accurately….similar to why the .40 S&W has more recently been dropped from some Law Enforcement agencies and they went back to 9mm.
I like fine revolvers in general - especially the .41 mag and the S&W models 57 & 58. I wish they were made in a slightly smaller frame as the “N” frame makes the gun heavy and if carrying it - might as well just go with the .44 mag, since you’ll be lugging around the same weight & bulk. (Recoil feels similar to me). I assume financially it would Not have made sense for S&W to develop an entirely New frame for the .41mag both because of the cost and the fact most shooters had trouble with the recoil on the heavier N frame already.
