Needs a little polishing on the ends, but it's a great squib rod for 9mm and up. I might cut mine down to 8-10" instead of a foot long, but you don't want to go too short and hit your barrel with a hammer either.
Brass is softer then the steel in your barrel. It will not scratch or damage the rifling.
A 9mm is .355 inches. So you want something a bit narrower.

This would work fine. I would probably hit the edges with some Sand paper just so you don't cut your hands on a burr.
You can honestly find something at homedepot. You want it to take up as much room in the barrel as possible, so it doesn't get wedged between the bullet and the barrel.
I believe you can find caliber specific squib rods online but you will pay a premium on them.
If you have a rubber mallet I would use it just to make sure you don't mark up the barrel if you miss :P
