Grant Cunningham, in his book "Gun Digest Book of the Revolver" does present a revolver malfunction drill algorithm. Here it is for what it is worth:
First symptom: the gun fails to fire:
Stroke the trigger again.
If the gun still fails to fire, reload.
If the gun fails to fire after the reload, drop it and implement your backup plan.
Second symptom: the trigger is locked, forward or backward:
Tap-stroke.
If that doesn't clear the jam, reload.
If the cylinder won't open, kick it open and finish the reload.
If the cylinder is still stuck, implement your backup plan.
If the cylinder won't close after the reload, implement your backup plan.
Explanation:
First symptom:
If the gun fails to fire due to a bad primer or light strike, a second trigger pull will likely correct the problem unless the gun is empty or all rounds are bad.
If the gun is empty or all rounds are bad a reload will correct the situation.
If the gun fails to fire after a reload there is either a malfunction such as a firing pin or transfer bar problem or all your ammo is bad, in which case the revolver is out of the fight.
Second symptom:
Tap-stroke is a sharp whack to the left side of the cylinder with the heel of your weak hand followed by a trigger press. If the problem was an unlatched cylinder this should fix it.
According to Cunningham, if the problem is a self-engaged lock on a newer Smith and Wesson there is a 15% chance the tap will correct it.
If the action is bound by debris in the channel that the hand moves up and down in, a tap may jar it loose.
If the tap-stroke does not work, the cylinder may be jammed due to a high primer or dirt trapped below the ejector star. In this case a reload will usually fix the problem.
If on attempting to reload the cylinder will not open, in a critical situation Cunningham recommends kicking it open by rotating it right side up, depressing the cylinder release with your shooting hand, and whacking the right side of the cylinder with the heel of your weak hand. If the cylinder opens and can be reloaded and then closed, function will usually be restored.
Note that if the cylinder is jammed due to a bullet caught between the cylinder and the forcing cone, attempting to kick open the cylinder will likely result in expensive damage. So this is a drill you use in a fight, not for a malfunction at the range.
