I may be adding another foster girl to the pin posse at my house. There are so many turn-ins it's so sad. But they really aren't the dogs for everyone. But the good news is that I now the Volunteer Recruiter for IN/IL area, and I preach the joys of min pins everywhere. :)
But as far as being a concealed weapon, they are much too loud for that!
My uncle's dad has a minature pinscher. He has a spiked collar on it and it's named "Bullet".
