Hey the Sp101 is a great gun, I have one in 357, The 9mm is out of production so far as I know, a 9mm small frame gun would really intrest me IF, IF the gun makers would shorten the cylinder and frame to match the cartrige, thus saving weight, otherwise if I have to lug all that steel around it might as well be reamed for 357 though I'm usually carrying the speer 38 spec snubbie load, unless in the woods when I carry Cor-bon JSP's which are not compleatly punishing to shoot from the Sp101 though it's the only snub I woudl try this with.
