Most common: In shootouts, Micah uses the player's animations to switch guns.

Cross-Draw: The only time we see Micah using this technique is in the mission "An American Pastoral Scene", after falling off the Stagecoach he quickly draws the guns to shoot some O'Driscolls.

Cavalry Motion Draw: Micah sometimes twists the guns as they're coming out of the holsters, it's a very smooth and quick draw.

The Bill Akins Draw or Micah's Signature Draw: Micah grabs the guns by the trigger guards with both of his trigger fingers and flips them forward. We can see him drawing like this in the missions "Outlaws From The West", "Blessed Are The Meek?", "A Short Walk in a Pretty Town" and "American Venom". It's a modern technique (modified version of the Road Agent's Spin) created by Bill Akins around 2008, probably in the game's history Micah is the creator of this technique and only used it for himself (This part is just speculation)
