Well, I shot my SP101 yesterday and I liked it, but only after I readjusted my hold on the gun. After that, the groupings were sufficiently tight.
Just shooting .38 target loads, the recoil seemed greater (or at least no better) than my lighter weight Rossi M88, but the Rossi has larger rubber grips. I think that the Hogue grips will be a necessity, and definitely help me shoot better. Shooting .357's with the stock grips will not work for me, I don't think.
I'm happy with my purchase.
