It's unburned powder. The longer the barrel the less you'll see of it. I get it in my M&P9 2.0. Not so much in my 8 inch 9mm AR pistol but there is some.

I get the same yellowish "sand" in my 16" PCC. Not sure which load is responsible since I shot Speer Gold Dot (115gr) along with numerous other ammo types (Win, Fed, and IMI).
So it's not just from shorter barrels, unless being blow-back contributes to it. |

I've always thought that was filler.

When I get a newer pistol I'm going to carry, I run drills at the range with Lawman, clean it at the range, and then run a couple magazines of Gold Dot through the clean gun to ensure function before carrying it until the next range trip. So, filler or unburned powder, it seems to be coming from the GD and, I would think, it would contribute to malfunctions (potentially) sooner than a load that didn't have/do that. The HST I tested recently, doesn't do that. |

I've noticed it with other ammo over the years, but can't remember which off the top of my head. I bought a used Swiss polizei P228 once and the inside was plastered in that stuff.

It's probably just they powder they use. Handloaders, like me, see it with certain powders like Ramshot Silhouette. The little yellow 'sand' residue is normal with that powder.
There's no need for 'filler' in any typical handgun gunpowder that's i'm aware of. Especially in the 9mm which has a very small case capacity. |

As seemingly impossible as it is, un-burned gunpowder is a thing. I'm not aware of any factory loaded ammunition of any caliber or type that uses "filler" over the charge of gunpowder... |

It's not simply unburned powder. Ramshot Silhouette is a dark gray / black powder, and the little bits of residue after shooting are yellow. I think it has burned, but not all of the granules are completely consumed in the process.

Smokeless powder (aka nitrocellulose) is that yellow to yellow-green color. We are used to it being gray to black because it's coated with graphite during the manufacturing process to allow easier metering. What you're seeing is the powder with the graphite coating burned off.
Google pix of cordite. It was an early form of smokeless that was uncoated. It is found in sticks that look very much like thin spaghetti. |
