Glock has had a .380 for a long time I think its a model 25. Doesn't have enough points to be imported or some other BATF craziness. I believe they sell them in Europe where people take a .380 pistol way to seriously. The last .380 I shot that seemed ok to me was my dad's colt. It was single action and small enough to conceal well.
The .380 is popular in some countries of Europe where civilians are cant legally own guns chambered in military calibers like 9mm Luger.
