I wonder why many European countries, and many Americans a century ago, believed they had enough gun when all they carried were .25s, .32s, or similar cartridges. Any of these would be considered today "underpowered" for self-defense purposes. I am not sure if bad guys used to give up after being shot once, if ease of carry outweighed power considerations, or if stopping power was less important than making a show of defending one's self. Of course, battlefield experience a century ago taught us that American soldiers needed a bigger bang. What are your thoughts? ???
