Yea Ted was really into that caliber. At one point He was talking about having a .32 h&r marlin 1894 recambered in .327 fed mag. I miss him a lot, I think about him almost daily.
As far as a carry gun length barrels go the .327 fed mag has the same power as a 9mm +p. Unless you are really stuck on a revolver I would consider a 9mm single stack auto. They will weigh with in an oz of the lcr and will be much slimmer. Also depending on the particular gun you will get one or two more rounds
