Sometimes El Sordo's bandoleers are full of bullets, sometimes they are missing several bullets - particularly the one over his left shoulder.
During the culminating gunfight, at one stretch when the camera does NOT leave Jim, Jim fires BOTH of his Single Action Army pistols continuously at least EIGHT times WITHOUT reloading!! That makes this an interesting trick considering that this model of a pistol only holds six rounds! Two less than Jim could have fired in this particular exchange.
When Jim meets the Mexican to get the map, Jim cuts him down but in the reverse shot of Jim the bandit's head is moved when Jim is in the shot.
When Jim rides off with the horse from El Sordo's camp, he's riding bareback (no saddle). Then it shows him riding off passing the cactus tree and there's a nice saddle and reins on the horse.
When shooting the anchor into the rock wall of the cliff, the gun actually moves forward (into the cliff face). The gun should have recoiled back toward West (and rather violently, as the anchor is directly in contact with the cliff face).
When Jim shoots the anchor into the cliff face. He took his weapon out of the holster placed the anchor into the barrel of his weapon. Blocking the barrel in that manner with a live round, would have blown the weapon apart.
Jim tells El Sordo that he's never met President Benito Juarez, even though he has, in The Night of the Eccentrics (1966) and The Night of the Assassin (1967). But there are two possible explanations for this within the series' world. One, some first and second season episodes have taken place in 1874 (two years after Juarez died), indicating they're not all happening in chronological order. Two, West may regard his encounters with Juarez as sensitive information which El Sordo isn't allowed to know.
As West descends the cliff on his grappling hook, the cords to a safety harness, running down from the grappling hook handle to West's waist, suddenly appear during close-up shots.
At some point when Jim and Arte are on horseback facing the Mexican honor guard, Arte's horse urinated. Note the sizeable mud patch beneath the horse, especially when Jim and Arte ride away.
After Jim and Arte enter the hotel, the door behind them closes by itself.
The people exiting the hotel lobby cast shadows on the backdrop.
Clean shaven stunt double for El Sordo.
When Artie shows up at the cantina dressed as Poncho, he is wearing two bandoleers loaded with spitzer bullets. BUT the show takes place during the Grant Administration (1869-1877) and the spitzer bullet was not introduced until 1898 (by the French Army), off by more than two decades.

When Jim sends the bandit off on the horse. He did not take the rifle, that makes no sense at all. The rifle holds more rounds and has a lot longer range.
The bandit tells Jim to meet him at a high pinnacle of rocks. But when the film shows the rocks they are actually a butte and NOT a pinnacle. As this is a Spanish word and would have been very familiar to Mexicans, this error is very surprising for this character.
When West and El Sordo are at the water hole, waiting for their 'company', West says, "It'll be dark in an hour." The shadows are at about a 45 degree angle, so sunset is at least three hours away.
