A Town Called Mercy (TV story)

 was the third episode of the seventh series of Doctor Who produced by BBC Wales. It was the first televised since 1966's The Gunfighters. Across all media, however, it was merely one of many westerns, and wasn't even Matt Smith's first western with the Eleventh Doctor, since he had read 2010's original audio, The Runaway Train.

Synopsis
A tale of war, betrayal and vengeance, converging on one small town in the Old West – a town under siege. Just crossing the boundary line summons a not-quite-human killer from the desert heat haze. The Doctor finds himself not just in the crossfire of an ancient conflict between a cyborg killer and an alien fugitive, but he is also faced with a moral dilemma: which side should he take? Who really is the victim here? This time though, the Doctor doesn’t seem to care...

Has the Time Lord been alone too long? Have the long days of travelling between his adventures with the Ponds taken their toll? Because for one of the few times in his long life, the Doctor takes a gun...

Plot
Kahler-Mas is running away from the Gunslinger and finally gets caught. There is one more person left on the Gunslinger's list: the Doctor.
