The .41mag was originally designed to fill a gap in law enforcement, but was never adopted due to the weight of the gun. Some departments (San Francisco California PD & San Antonio Texas PD) did issue them and they were carried for a while but soon replaced with semi-auto pistols.
For the civillian though they were accepted by many. Some, like me think they are the best revolver round out there. I have been shooting with & hunting with it for over 20 years and all three of mine are stainless Redhawks. I love to handload and can really taylor loads to my liking, to do anything I need them to do. Here are my three guns. A 7.5" with a 2X Leupold Scope, a 5.5" and a 4" I made from another 5.5" before Ruger copied me and built their own.
