I ended up using Rub'n Buff to get the stainless steel look on them. I initially tried using various silver metallic spray paints but nothing was quite shiny enough for me.
For the grips I used a medium gray, I can't remember the exact paint. I had a lighter gray initially which was more accurate but I like the contrast between the medium gray and chrome barrels so I switched to that. I then dry brushed metallic silver paint on the grips to give it a slightly metallic appearance.
For the bronze areas I used FolkArt Metallic Bronze acrylic paint.
