I've shot the Ruger SP-101 and GP-100 in .357. Much prefer the 4.2" bbl length, in both, as I feel they balance better under fire. But, if you're prepared for the relative snappiness of the .357 in a 3" bbl revolver, the SP-101 is hard to beat, IMO. Myself, I'm more accurate (in follow-on shots) with a sidearm that's got a bit more heft and a bit more overall foreend/barrel weight to it. Of course, nearly one and a quarter inches longer, the 4.2" bbl SP-101 will take up a tad more length carrying it.
