IDPA Divisions Explained in 60 Seconds (BLUF)

Short answer: IDPA has 8 divisions, and the right one depends on the gun already in your safe. Full-size 9mm like a Glock 17 or M&P 2.0 → SSP. Same gun with a red dot → CO. Compact carry like a Glock 19 or P365XL → CCP. CZ Shadow 2, 1911 in 9mm, or heavily modified Glock → ESP. 1911 in .45 → CDP. Revolver → REV. Pocket 9mm like a SIG P365 → BUG (now 8+1, .380 is out as of 2026). 9mm carbine with a 10"+ barrel → PCC. If you’re new and own one 9mm pistol, default to SSP, CO, or CCP — lowest cost, biggest beginner pool, easiest to learn in.
