My friend had a DB380 that didn't work....then it broke, then it failed to eject, then it broke again then it didn't work. It did make a couple trips to Florida and back. The positive side is it looked cool and it hid very nicely. He named it "That Freakin POS mistake".
He no longer has it and I am not sure were it went, I don't ask about it anymore, he fails to see the humor. The DB9 might be a better weapon, I am not sure. There are too many good little 9's out there for me to consider this one but I have a pretty biased point of view from hearing my buuddy cuss Diamondback out for a few months last winter.
I am sure there are some out there who have had good experiances with DB and proabably with the 9. Sorry for not really answering your specific question, I just don't want to see anyone else name their weapon similarily.
