Nope. No buying "sand". Plus, it isn't sand. Sand blasting will make a pretty rough surface and remove a bit of material as well. What I have access to is a glass bead cabinet. It uses glass beads. They leave the surface dull but smooth and don't really remove any material.
You would need the .308 tools though. Or we would have to take some time masking off everything we don't want blasted.
The 1911 I posted earlier started life looking like this...
Then I got bored and polished it...

Then I decided that was way too much bling and really showed fingerprints so I bead blasted it.
