I actually asked this question (327 LCR-x) to the Ruger company reps at the NRA meeting in Louisville in May. He turned to another guy and repeated the question to him. He replied, "Maybe we need to do that. Third person who's asked today.". So there is a chance.
I was handling the 3" 38spl and I like the longer grip. He asked if I had the LCR in 327 since I had asked about that round. I told him I did have it and all the other 327 Federal guns Ruger has made. I added that I had a good number of 32H&R's that Ruger has made but not all. I went on to tell him that my first handgun was a Single Six 32 in 1985.
I offered up that to me, the 327 would be an excellent round for a "kit gun" like the 3" LCR. Six rounds of a decently powerful round in that package would be right in my wheelhouse, so to speak. He said that he hopes they make some for me and I thanked him before moving on. I never thought the LCR would get made so it could happen if the short ones sell ok.
