Just buy 9mm by the 1000 (or more), reloading for 9mm is almost not worth it, you don't save very much over the cost of bulk factory ammo and you will spend a lot less time sitting at the reload bench.
I reload for 9mm a little but mostly just shoot American Eagle bulk or whatever I find cheapest between Canada Ammo, Frontier, and a couple other site sponsors. UMC 250 round boxes from Cabella's is also a decent deal.
I love my Sub2000, it's really fun. Don't listen to the posts about it being cheaply built and overpriced. What else can you buy for $600 that is this much fun?
Mine hasn't given me any trouble in over 1000 rounds (I know, that's no torture test but this isn't a mil-spec battle rifle) other than a couple stovepipe stoppages early on. Mine feeds well from all mags including the KCI ones.
I bought a generic rail and drilled and used blind nuts to install it under the front of the forend and installed an AFG and it's much better (for me anyway).
I also emailed Tacticool products and got their rubber sleeve for the tube (much better on the cheek when it's cold out). Don't bother with their recoil buffer though, it stops the bolt from being able to be locked back.
Enjoy
