Vintage Firearms is my NPC's "Money" Johnson's hat. So far, he's shown his 165-year old (In 2070) Holland & Holland Royal Deluxe Double Rifle in .600 Nitro Express. He also has bolt-action rifles from every major side from WWI and WWII, and uses a Holland & Holland-made SMLE No. 4 or a sniper-grade Kar 98K for his "Hunting Rifles" in Seattle with him. All legally owned. (Only the Royal Deluxe Double Rifle has been seen, however.). His Grandfather swears by IMI-built weapons, and has every type of Uzi ever made, but typically relies on a Uzi-III in 9mm Caseless, but also packs a Centennial-edition Colt M1911A1 in .45ACCP made in 2011.
Money's good chummer, Murphy, has a vintage Ares Predator Mk. I, stock save for replacement parts, that he uses as his standard sidearm, swapping out the barrels whenever he needs to give it a new ballistic profile. It's been in his family for three generations of Shadowrunners (He's an ork), and has probably seen more action than some entire Shadow teams.
Although I've never gotten around to mentioning them much, Nas' family has a bunch of vintage firearms as well, with his brother favoring a M-14 rifle set to fire semi-automatically only for big trouble, but mostly carries a classic Ruger Redhawk revolver in .44 Magnum with custom vat-grown walnut grips, and a Henry Big Boy Lever-Action Rifle in .44 Magnum with equally custom furniture. His family owns a farm (One of the few still in non-corporate hands) and is right on the Texas/Aztlan Border. Nas spent most of his time driving, while his brother spent his time shooting, so he's a crack shot.
Yes, I think entirely too much about the backstory and history of all my characters.
