Depending upon how my joints are working, and what I'm wearing, I'll carry (in order of frequency) Taurus 709, S&W 642 Airweight CTL, Glock 23, or Bersa 380cc. My favorite "shooter" is the Glock; we're really old friends, but the Taurus, cocked & locked w/8rds of 9mm Federal Hydra-Shoks, goes anywhere & is more reassuring than either the Bersa or the S&W .38 spec. - plus the Taurus has "real" sights, a manual safety & a trigger I really like. Obrigado, Brasil!
I have a variety of holsters (don’t we all), but my favorite for the Taurus, S&W or Bersa is actually a digital camera case. It hangs on my belt and just screams "old geezer with a camera", not “gun”. The hanging loop let's me swing it out of the way of the seat belt when I'm driving. The zipper is smooth as silk, and a simple 1" steel-split-ring on zipper tab makes it a cinch to open without fumbling. It also has the advantage of my wife NOT thinking it looks like I'm carrying.
I like the Bianchi nylon pocket holster for pocket carry. Works on jeans, slacks, and inside breast pockets on jackets. I’ve tried IWB route, but there's too much "me" inside the waist-band already.
