I understand why single action revolvers chambered in 44 Magnum are not that popular. My introduction to the 44 Magnum was with a Ruger Super Blackhawk, blued, 4 5/8" barrel, shooting 210 grain JHP full power loads. I fired 5 rounds and the web between thumb and index finger hand a nice, bleeding cut in it. I proceeded to fire 10 more rounds just to prove to my friend who had invited me to this range that I was not only tough, but stupid enough to repeatedly prove how tough I was. Yeah, young, tough, and stupid, those were good days.
I expect there are plenty of shooters who buy one, fire a few cylinders full, then use it as trade fodder. That's just my opinion and rambling musings and worth exactly what you paid for them.
