You will need small pistol primers for the 9 and large pistol primers for the .45. When you get 'em, the difference will be obvious. Just look at the back side of the case, small is small, large is larger. Get STANDARD primers, not magnum, for these calibers. Frankly, I use standard primers even in magnum revolver loads.
For powder, I use Alliant Bullseye in both calibers for standard range loads. Unique will work, but Bullseye is better. Also, WW231 is a good powder for these calibers. There are MANY good powders, but Bullseye has been around forever and why fix what ain't broke? It shoots accurate and reliable and meters well. WW231 is a little cleaner burning.
