The SIZE of the primer is determined by the particular cartridge case that you are reloading. For your cartridges, 9mm takes small pistol primers, while .45 Colt takes large pistol primers.

The reloading manuals will tell you what BRAND of primers were used to produce the pressure-tested data, and whether they used STANDARD or MAGNUM primers with each powder.

Of course, if you are ordering primers and the reloading manuals at the same time, then you won't really know what you want to use at the time you order. In that case, I would suggest CCI standard primers in both the small and large pistol sizes for the cartridges that you specified, since they are used for a lot of the manuals and are usually available.

Or, if you tell us which manual(s) you are ordering, we can check our copies and tell you what brands of primers they used so you can match them with your order.
