Since this seems to be the most current and most active ".327 Federal Love" thread, here's a handgun that I didn't actually know existed:
USFA Sparrowhawk, .327 Federal Mag.
It's a single action hogleg with a 7.5" barrel and an 8-shot unfluted cylinder.
It's not cheap, with an MSRP of $1,495.
Not a bad little addition to the small collection of .327 Federal Mag hardware.
