When Marshal Dillon and Chester are target-shooting on the range, Chester takes aim and fires 3 shots at a can on a log before striking it. Dillon then draws his gun and fires 2 times hitting the can. Without reloading, Chester then tells Dillon he's going to "fan" the pistol in his next attempt to hit the can, destroying the log in the process. He raises his weapon and fires six shots by fanning the hammer. He could not have fired another shots without reloading his six-shooter first.
Chester stays inside the stage while the other 3 passengers get out. This means they all had to climb over his stiff leg. He should have made it easier for them by getting out first.
