I have a 38 LCR and a 4" gp100 and love to shoot 38sp with both, but I now want to add something in between the two in size. I am looking at the 4.2" SP101 but there are none to see in my LGS so I will need to order it sight unseen. I have owned a few SP101's in the past but they were the snubbies. I am hoping for something somewhat close to the balance and feel of the 4" GP100, though lighter and smaller; something around the size of a SW K frame, but a Ruger, not a K frame. Feel and balance are very subjective, but if you own such a 4" SP101, I would appreciate your comments on the feel and balance.
