I reload for 9mm because . . .
1. I can make custom loads for different purposes. I have a great light load for IDPA type competition, general range use and teaching new shooters.
2. My reloads are high quality using quality bullets, powders and primers. One of my friends said that my reloads look better than the factory rounds he uses.
3. 9mm brass is abundant and usually free since most have buddies who don't reload 9mm.
4. I enjoy reloading and reloading for my 9's gives me more reloading time.
5. I shoot more than the average person.
6. I already have the equipment to reload for other more expensive calibers. You can save a bunch if you reload for .45 acp and .357.
If you are just a casual shooter, it doesn't pay to reload.
