I would recommend starting out running some basic drills, with someone who has spent some time in USPSA. I do this, pretty much weekly. Real short, shoot and move drills.
One example only requires 3 targets and 2 barrels. Set the targets out to 10-12 yards, spaced about 3-5 yards apart. Use the barrels as an "A to B" location. From the buzzer, draw while standing behind barrel A and place 2 shots in each target. Then, while moving/changing mags, get to barrel B and repeat with 2 shots per target. All the while, minding one's safety fundamentals, and watch the 180.
In addition, any local steel challenge matches are also a very good way to start out. All static shooting. This provides great training for drawing from a holster, gathering a clean sight picture, trigger control, and target transition.
Hope this helps.
