I've had an S&W model 37 for a lotta years and couldn't be happier light,accurate ,and never jams like a lot of pocket autos tend to do.Carry it in a Galco horsehide pocket holster with a couple of speedloaders.However the airweight Smiths with the shrouded hammer are a better choice (the old model 38) there are newer versions but I don't know the model numbers.
