You can't beat the CCI/Blaser rounds for plinking or targets. For personal defense/carry, I've been using some MagTech First Defense in my S&W 642 lately, and I've used their Guardian Gold rounds before. I got a few odd looks the last time I took the Airweight to the range and loaded it up with MagTech rounds, and some guy mentioned how he, "Heard a friend say that a cousin had feeding issues," with MagTech rounds. Not too many feeding issues with revolvers, but whatever.
I'm a big fan of Hornady's TAP rounds (I keep my XD .45 loaded with them when I'm using it), but, alas, they don't make them in .38 Special.
