1. With one exception, sorting brass is a waste of time, since the error budget from brass heritage variations will be less than that from a host of other factors, with a 9mm auto.
2. The except is military; some military 9mm employs crimped primers; some does not. Any military that you acquire for the first time should have the primer pocket swaged as a precaution.
3. That said, a potential implication that some might see in some of the above replies is that there is no need to inspect brass. I don't know of that was intended by the responders, but I think failing to inspect brass, including your own but especially stuff the prior history of which you don't know anything about, would be foolhardy.
4. Some people refuse to reload "range brass." Their theory is that the cost of brass isn't high enough to run the risk. I'm one of those folks.
