The IDPA range commands for all shooters are the same, for 1911s here's how it works.
- Go to the line with an unloaded and holstered firearm
- When the RO says "load and make ready" draw your 1911 and insert a magazine
- rack the slide to chamber a round
- engage the safety
- and holster
You will then assume the prescribed "ready" position, and the RO will say "Are you ready" then "standby". After standby the buzzer sounds, and you'll draw from concealment to engage the array of targets. You should have a cocked and locked firearm with the safety on - so once the muzzle is pointed downrange, sweep the safety off as you prepare to engage.
The 1911 pistol is designed to be carried with a round in the chamber and the safety on with the hammer cocked. Any other method of carrying a loaded 1911 is unsafe compared to the "Condition 3".
