Both VV N320 and Hodgdon TiteGroup seems to be well regarded for 9mm comp loads with the nod going to VV for its cleaner and cooler burning, and softer recoil for the same PF. Unfortunately Solomon's, which is right around the corner for me, carries everything under the sun except VV powders. Any other vendors nearby peddle the stuff?

have you tried AA2?

You might not be able to find N320 locally. But you might want to try Powder Valley (http://www.powdervalleyinc.com/) they tend to have it in stock at fair prices. Also you can get other reloading components while you are at it.

I use it for my 40s&w and 9mm production loads. It is more expensive than others, but I prefer it for it's overall performance. A lot of shooters that I have run into also like Titegroup. Offers the same performance but it is a bit dirtier.
