i'm saving up for a BUG/secondary deep concealment gun. i'm torn between two choices though: .38 special snubby and sub-compact 9mm. it will be for pocket carry. i like the snubby, and i like the 9. but from a defensive point of view, which will have the best terminal ballistics out of a tiny barrel? which would ya'll recommend, and in which weapons? my local gun store has new s&w 642's, hammerless, for about $400, but i was also thinking about the charter arms off-duty. or i could go with a small kel-tec or kahr for around the same price range. capacity is only a difference of 1 or 2 rounds. help me decide!
