Bob,
I got an SP-101 in .327 last August, and after installing a Wolff spring I liked it so much that I snagged another SP-101 in .357 about a month ago. I put a Wolff spring in it, too.
I won't say I've really tested either for accuracy, as I tend to do most of my shooting rapid fire at close range (7-15 yards). I generally group them in about a hand-size pattern, and that's really about what I expect from myself with a DA revolver in rapid fire. When I slow down and aim at a certain spot of the target, I either hit it or hit close enough to suit me as long as I do my part. Drilled a Coke can with a .327 last weekend and launched it about 20 feet up into the brush at the top of the dry streambed where I was shooting!
I don't have a CCW (I teach JROTC at a high school and couldn't carry there), but when otherwise occupied I put either Ruger in the car with me. Or I take the .357, the wife takes the .327 in her car, and daughter takes the S&W .32 (recoil-shy) in hers. These are secondary houseguns, too; primaries are 4" S&W and Colt revolvers. My point is that I own and like all of these brands. Just got a beautiful used Service -Six because I'm now a big fan of Ruger DAs, and have had 2 Ruger SAs for last 10 years, too. All of the Rugers are the proverbial "bank vault" strength and 100% reliability.
If I had a CCW, I'd carry the Colt D.S. of my current guns, as the Rugers are a bit larger and heavier. On the trail, either Ruger would be fine except that's where the lack of elevation-adjustable sights could prove a problem. I'd have to carefully select the best load for POA=POI.
As always, mileage varies based on (a) what you really want or expect from your gun, and (b) whether you get a lemon or a shooter. Although my Rugers have been completely trouble-free, that no longer seems to be the case for everybody.
