The International Defensive Pistol Association (IDPA) is an organization that promotes defensive pistol shooting as a sport. It was founded in 1996 and it's based in Berryville, Arkansas.
The IDPA uses equipment and ammunition simulating "real world" self-defense scenarios. Shooters competing in events are required to use practical handguns and holsters that are deemed suitable for self-defense use.
Some Top Shot contestants regularly compete in IDPA events. Some of them are:
- Craig Buckland - Is a IDPA 5-Gun Master
- Denny Chapman
- Brad Engmann - Holds a master-class certification
- Jarrett Grimes
- Dylan Fletcher - "Behind the Bullet" informed that Dylan had started competing after his appearance in the show.
- Amanda Hardin
