George,
Where would one go to get some training for USPSA in the Northwest? I am a believer in training for whatever shooting occasion one might endeavor to be competent whether its self-defense, pistol competition, or breaking clays.
I have kind of narrowed down my gear thanks to your suggestions, BrianEnos forum suggestions and those of a few of my buddies that shoot USPSA. I am leaning toward a CS Speed belt with Bladetech DOH and magazine holsters for my XDM 45 to start out. I will be getting the books George suggested as well as develop a training regime that will consist of a lot of dry fire drills with some live fire once a week or so.
One of my classmates was relaying the story of her boyfriend at the age of 20 something deciding he wanted to be good at something and took up long distance running-he ran an ultra marathon last month in his 40s (crazy I know). I've decided to be good at USPSA, Master would be okay but GM would be awesome.

Aim high, that way if you miss you're still up there somewhere...
