His tattoo's could have a deeper meaning. Maybe they guy is German. Maybe he collects pistols. You should have a passion about whatever it is your getting inked so maybe this guy does. Good for him!
Being a person that worked in Law Enforcement
id have to say if I were going with a tattoo of a pair of guns they would have to be Glcoks
because of there iconic statis. The term Luger litterly carried over to define a 9mm.
