More Divisional Section Information Below

IDPA is divided into five divisions that are entirely separate. None of the following divisions compete against any other division.
The type of firearm the competitor uses will determine in which division he/she shoots. Pistols shall be classified first by action, then by caliber.
Double action, double action only and safe action pistols compete in the Stock Service Pistol Division SSP. Any gun that can be used in SSP can also be used in the Enhanced Service Pistol Division ESP or the Custom Defensive PIstol Division CDP, depending on the caliber, otherwise, single action guns compete in ESP or CDP, depending upon caliber. Revolvers shall be classified by capacity and loading method.
