Everybody in the fam refers to my Kimber as Mz.Kimber.
Years ago, the first little .38 got nicknamed "Liberty" because a gal I know got a twin to it and called it "Justice"...so we have "Liberty and Justice for all."
Other than that, I had a rifle handed down to me that has "JW" carved in the stock. There are no "JW" initials in my fam, so the running joke is that it was John Wayne's gun...so we call it "The Duke".
How in the heck could I remember them all if I named them? No, just seems stupid to me. Seriously though, I currently have 25 guns, that would be a lot of names.
