Aluminum grip frame, scandium alloyed aluminum reduced size cylinder frame, 5 shot titanium cylinder, 4 5/8" stainless rifled tube inside an aluminum sleeve with a flash light mounting rail, rubber laser grips, a red dot sight on a see through mount, tritium night sights, and an aluminum loading lever and ram rod. The Ruger New Army!
Seriously, after an unfortunate trade my first Old Army completed a pair kept for protection by a retired gent while gold panning the desert streams of various states in the middle of the country. He figured rural sheriff deputies weren't going to hassle an old geezer over muzzle loaders. That's the most logical rational I've heard for a carrying a SA for protection, but what the heck, I'm sure quite a few plastic fantastic fans think carrying a DA revolver is absurd, and we don't need to keep up with the SWAT team.
