I actually carried a model 58 for several years back in the 70's. I only know two other LEO's that carried this caliber. Most officers didn't even know what it was or what it would do. I quit carrying it when my department issued mod 66's, then 686's, then the Glock 17. I own several .41 mags now and sometimes CCW the 3" 657. I have a longer barrel 657 that I have deer hunted with and frequently carry it when riding my 4-wheeler.
