Join USPSA and then look for special classifier matches in your area so you can get classified in the Single Stack division.
(I REALLY like classifier matches in both USPSA and IDPA so I always advise people to go shoot them as a way to develop their basic skills)
After a few matches, you'll be refamiliarized with how everything runs and which guns fit in what divisions, and what equipment you might want to get. You may even find you want to buy more guns
