I own Berettas, Colts, Rugers, Smith & Wessons, Charter Arms, Taurus, Rossi, and many others. If they are for SD, all I care about is how well they work.
I have owned about twelve Taurii. Only one gave me problems. I mailed it to them, and they fixed it for free and mailed it back to me. The others have been fine. They tend to have mediocre triggers. A few of them have had great triggers, though.
I owned a Taurus 709. It worked fine. Unfortunately, after I took it to the range a few times I realized that my fingers were way too long for it - it was just a poor fit for me. I traded it in on a Ruger LC9, which fits me better and has functioned perfectly.
I am more of a revolver guy. I keep a medium-framed 357 for HD. For carry I prefer my hammerless 38 snub, or my shrouded 44 special. In extremely light summer clothing I will carry a 380 (the Kel-Tec that is extremely similar to the LCP).
38, 357, 44, 45, 32 magnum, 10mm, 40... they are all fine. If you do your part, they will do theirs. The handgun that feels best in your hand and that you shoot the best is the right one for you. For me that is a revolver, but everyone is different.
