Get online and find a match at a range. They typically want you to have your ccw, but it's not a must. You need about 100rds, at least three mags and a holster that you carry with. Most of the scenarios are real life type things. For instance, gun holstered, you run to cover, draw, tap tap.....run, tap tap tap...cover, etc. The cost is roughly $15 and it lasts about 3hrs depending on the amount of people that show.
I have some vids of me doing it on youtube somewhere I will hunt for.
Edit: I use my IWB holster and I bought a fobus two mag OWB holder for easy reload on the run. You're reloading and leaving empty mag on ground until your run is over. Then gather your stuff after scoring.
