I just bought a brand new blackhawk and I noticed that the safety warning was on the bottom of the barrel by the ejector rod housing. Did I get a fluke or did Ruger finally wise up and move the warning?

Pretty sure it just got moved. Have seen this on some other boards.

They simply moved it due to customer requests. Chief aka Maxx Load

I bought a new 5 1/2" Ruger SBH a year ago and the warning is on the bottom of the barrel on mine too. Finally wised up!
