I've only got two .41 Magnums (Magna?), but they see plenty of use. Bought both in 1999 from the same dealer here in the PRM (People's Republic of Maryland), and on the same day. The first was a 657-4 Mountain Gun, which the dealer stated had been sitting around for "quite a while." I didn't hesitate to scoop it up. Then, of course, he said, "You know, I've got another .41 around here somewhere if you want to look at it." Mom always taught me to be polite, so naturally I said yes. After a minute or two of rummaging, he brought out a NIB 657 with a 3" barrel, which he said had been part of a special run in that caliber for some wholesaler whose name escapes me at the moment. That one was decided upon even faster than the Mountain Gun. Food budget was a bit light for some weeks thereafter, but I truly enjoy those .41's!
They now both wear Pachmayr Presentation grips and shoot like the dickens.
