Twin S&W .38 Specials.
The plain-jane model (right) is mine, a hammerless SW 642 ankle gun. The only thing I did was change to a pair of nice soft Hogue boot grips.
The other is a SW 637. I had it built as my wife's first concealed carry gun. The trigger and hammer have been smoothed, polished and reduced. The smith also did a great trigger job, and installed an XS Big Dot front sight. She uses the larger Hogue full grip on hers.
Both of them get fed the Speer 135gr +p Gold Dot JHP, with plenty of light FMJ reloads for plinking.
