I have a Blackhawk convertible that I shoot exclusively in 9MM. I find the accuracy acceptable though not spectacular. I realize the bore diameter differential between .357 and 9MM is miniscule, but I have considered having a true 9MM barrel fitted. In addition to finding a gunsmith to do this I wonder if its worth the effort and cost. I do shoot this frequently since I have moved from semi-autos to revolvers because they are so enjoyable.
