I JUST bought a Hogue grip for my SP101. WOW... what a difference from the factory ones! Definitely bigger, and the tacky feel of the grip eats up a lot of recoil, I haven't tried 357's out of them (yet) but from the difference between them and the factory grips, I think they should do much better on the 357's...
You can get them in hard nylon also I think, if you want to carry it for CCW.. The gun is built like a tank.. I can group less than 2" with them on .38SplSWC; which is incredible for a fixed sight 2" snubbie...
The Hogue's feel great, and once you get a good grip on it, yep, you'd have to cut the wrist off to get it from my hands also. There were a few articles a while back about how snubbies are great defensive guns, possibly the most difficult to wrestle out of people's hands.. I have friends that hate revolvers, but a few after shooting with them, had to admit they were pretty awesome.
My SP101 was loaded with 125Grain JHP 357Mags, that was what was by the night stand for 2 years
No worries about magazine fatigue etc... I love revolvers..
