Much as I love the SP101, wuchak is full of it. Taurus makes some danged good guns at danged good prices and I have 3 of 'em. Smith and Wesson seems to put out more crap these days.
I've owned 7 Rossis over the years, Interarms guns. I had one in .357, the 971, same frame as the 462 I'm pretty sure. I put probably 5K rounds through it, some hot .357, more of it mild .38, probably 5 to one .38 over the years. It never got loose, always shot straight, good little gun. I had a problem with it that I got fixed, the firing pin snapped. Still shooting good when I traded it. I have a little Rossi .22 kit gun and an old M68 3" that I will not part with. The old M68 is REALLY well made and fitted. That was not the norm in the late 80s, early 90s, fit and finish wasn't quite up to mine I got in 1981. It did get back to the good ol' days after Taurus bought 'em out, fit and finish much better than the early 90s interarms stuff.
You won't find Rossi's DA triggers as light as Taurus or Smith, but pretty smooth and usable. I've considered buying one, might, yet. Academy has 'em for under 300 bucks in stainless. The SP101 is a stronger gun, of course, but I can also say that about any other brand in comparison to the Ruger. If you have the bux, the SP101 is the toughest little .357 out there and easy to tote IWB.
