ive been jonesing for a .327
im not sure which one is gonna fix the itch
but the GP-100 and SP-101 are become pure expensotainium!
And my brother, Crankylove, owns a .327 SP101; so we've had plenty of experience there, too. Even he admits that he'd rather have the GP100, unless Ruger offered the SP101 with a longer barrel.
