I started shooting late in life and just enjoy shooting no matter what it is. I started shooting IDPA 10 years ago and four years ago I started shooting USPSA and love it. It is easy to go from IDPA to USPSA, but harder to back to IDPA after shooting a USPSA match. There are some very good shooters in IDPA, but the caliber of shooter in USPSA is much higher. All I can say is I shot both, I have fun, and meet a lot of great people.
