During Final Crisis, Batman wields a pistol to during a confrontation with Darkseid. Having learned of his weakness to radion, Batman acquired the weapon and a bullet made of the material, citing the confrontation as a one-time exemption to his no-guns rule.
During 1939 and 1940, in both Detective Comics and later his own title, Batman, the character was shown carrying and using a gun. "There's an incident [in Batman #1] where a bad guy is escaping and Batman dives on him with an airplane and machine guns him," O'Neil said.
Batman's use of lethal tactics finally stopped after Batman #15. This issue was notably one of the largest sprees in his history, causing a vehicle crash and later destroyed an entire warship full of soldiers. The cover also depicted Batman using a machine gun on the cover of the issue.
I took that little vignette from a scene in The Dark Knight Returns, and at the end of that, he shoots the guy right between the eyes with the machine gun. For the record, that same gang member that was going to kill the kid shows up perfectly fine later to confirm Batman shot the wall behind her, not kill her.
Unconventional weapons and tactics, like batarangs and grappling guns, are more successful for Batman than guns. Batman's strict no-gun policy not only prevents accidental killings but also disarms enemies effectively in Gotham City.
If he used guns against criminals, all of the training he had endured would become invalid. So, while Batman doesn't use guns because he has no desire to be like the people he fights, he also doesn't use them because he is entirely too good with them.
Arguably the most iconic weapon in the super-hero's possession, the batarang is Batman's go-to weapon when it comes to subduing and apprehending clown henchmen or mafia thugs. Starting out as just an original take on the classic boomerang, the batarang has evolved over the years to become a multipurpose weapon.
Batman using guns is one of the most controversial themes surrounding the character. Batman's no-kill rule is often remembered in several stories, but has also been forgotten in some adaptations. Ben Affleck's Batman, who came to use machine guns and equipped his Batmobile with firearms, is an example of that.
Batman has killed the Joker, Darkseid, Hugo Strange, KG Beast, Dracula, Two-Face, and many small-time criminals in different stories over time. There were several other instances where Batman killed, especially in the DCEU. Having a Batman that kills works well if it is used as a surprise for short periods.
Using the Mangler, Batman was able to effortlessly bend the barrel of a long gun. After pursuing Scarecrow's van, he used it to rip through the sheet metal covering the vehicle, which weakened the structure of the van, allowing Batman to crumple and stop the vehicle after landing on it from several meters above.
If Batman is against guns, why do his vehicles have them? His guns are designed to incapacitate his victims or put his enemies at a significant disadvantage. If his vehicles have grenade launchers they automatically calculate the explosion proximity so that his enemies are out of the fatal blast radius.
John Wayne owned many Colt Single Action Army revolvers over his lifetime, the classic Hollywood Western sidearm, but the actor favored one particular revolver so much that he wore it in several well-known films toward the end of his career, including the legendary 'True Grit.
Batman's lack of superhuman abilities makes him especially vulnerable to physical trauma, as his body cannot withstand continuous beatings without severe consequences. Batman's past trauma and lack of emotional healing make him easily manipulated by his enemies, who use his fears and personal losses against him.
Joker carried a customized Smith & Wesson Model 15-3 revolver with a telescopic 21 inch barrel. The trick gun could fire powerful explosive bullets or function as a harmless Bang! flag pistol.
The anti-gun feeling is up there with 'no killing' and the fact that Bruce Wayne is a socially conscious philanthropist (and not just a brutal vigilante) as one of Batman's most defining character traits.
Colt MK IV Series 80. In the Knightmare, Batman's sidearm is a Colt MK IV Series 80 with faux ivory grips. He uses it to kill a resistance fighter who betrays him and several of Superman's soldiers in the ensuing fight. Batman draws the Colt Series 80 pistol as he shoots the traitorous resistance fighter.
Batman rarely used a gun on people, but originally didn't have a rule against doing so. The character's shift to an anti-gun status is often said to be have been an editorial decision. The people at DC Comics couldn't understand why Batman needed a gun when none of the other DC heroes used one.
This implies that when he launches himself into a fight, Batman's detective skills allow him to determine whether his enemies are willing to shoot or not; by doing his research and playing up intimidation tactics he can make sure that the majority of combatants are unwilling to target him at all.
The first villain Batman ever faced was a man named Stryker. Despite that legacy, there's a good reason you don't see him around. In 1939's Detective Comics #27, Batman punched him over a railing into a vat of acid. His immediate feelings on the matter: “A fitting end for his kind.”
