I own a Ruger sp101 and a blackhawk in .327 federal magnum and just love them both. I have thought about selling the blackhawk just to make room for something concealable but the gun is so well made and shoots just great that I quickly change my mind. My opinion is that this round really shines in the blackhawk for hunting coyotes, which are a pest by me.
The sp101 coupled with the 6 rounds of .327 really make a great, balanced revolver. I love it and often carry it concealed. Great gun.
I love shooting .32 s&w long wadcutters out of the sp101 too. It makes a great day at the range.
