Factual error: Major Robinson threatens Steed with a revolver equipped with a silencer. A military officer would certainly know better. Though it's a common movie and TV cliché, it is a glaring error. Revolvers are open-chambered, allowing sound to escape out the back of the barrel - so they can't be silenced. There are rare exceptions if the gun is heavily modified to close the open chamber gap, but that does not apply to the weapon featured here.
