I bought the Lee Deluxe 4-piece die set, which includes everything 9x19p stated in post #5 as well as the collet die. The difference is (to my interpretation) that the full length sizing die sizes the whole case whereas the collet (or neck sizing) die only resizes the neck and bumps the shoulder, the rest of the case remains fire formed to your chamber. The advantage of this is you work the brass much less, which prevents it from work hardening and becoming brittle. This extends the life of the brass, and if you anneal the neck properly you can get even more life from each case.
the reloading vets can correct me if I've explained this wrong
