When I carry a sd revolver, it’s a M 38 in my pocket.

I like these more than the current iterations (eg 638). They’re dainty: the newer ones are clunky by comparison, but the newer ones are the best pocket pistols currently made.

I don’t use a pocket holster.

The oft mentioned concern about pocket lint getting into the works is unfounded. In 30+ years, I’ve never had a problem.
