The 327 really needs the extra barrel length, in my experience. I only have one 327 in a 2" snubby (It is a Taurus stainless). I think it would need to be at least 3" to get the higher velocities touted for the round. I saw pretty significant differences chronographing a 3" SP, the 4" GP and the 8 shot BlackHawk with a 5.5" bbl. Federal American Eagle 100gr rounds did 1350-1375 in the SP, 1425-1450 in the GP an 1500-1525 fps in the BH. That load was about 75 fps loss for each inch of barrel.. That would mean 1275 to 1300 for a 2" LCR - not bad, but not great.
I would get one either way (Big shock, Hugh?). I would prefer a 3" gun anyway.
