When I have been asked this question by acquaintances, I have suggested they consider law enforcement (LE) trade-in pistols.

Compared to its 4-ounce, 3 5/8-inch Short Mini-Revolver cohort, North American Arms' Mini-Master is a giant. But at 7 7/8 inches long, 3 5/8 inches tall and weighing 10.7 ounces, it is still more compact and lightweight than most of the centerfire handguns on the market.
For cloistered lefties, like myself, the Charter Arms Southpaw provides sanctuary. The cylinder and ejector rod swing out to the opposite side so the left-handed contortions (penance) during a reload are no longer required. It's really a reverse-configured version of the company's Undercover Lite.
