I love the 9MM round. They have made huge strides in that round over the past few years and it's still cheaper than anything else. 9mm+p+ ballistics are very near 357 mag and 40 cal (two rounds that are widely considered to be in the top 5 best all around defensive rounds).
All of that said, for myself, I would never consider any of the present 9mm revolver offerings. I don't like moon clips and Charter Arms' system, while it's intriguing, seems like added difficulty and not 100% easy (like a revolver should be) and you can't use speed strips or speed loaders with 9mm revolvers.
I'll continue paying $.04+- more per round and a slight lose in ballistics for the ease of loading/unloading, and carrying 38.
