With all due respect to the .41 Mag lovers, there was no need for this caliber when it was developed. All situations were covered by the calibers that existed already--ie--.38 Spl, .357 Mag, .44Spl, .44Mag, and .45Colt. Handloaders could tailor anything that they needed from one of these. There was NO void that needed filling---IMHO, of course.
