* A one-shot character in ''Anime/KirbyRightBackAtYa'' wields a machine gun/sword/flamethrower.

* ''VideoGame/{{TAGAP}} 4 features the AMM01, aka the Adaptive Multi-Munition Weapon System 01. It can analyze different types of ammo to learn how to use them; this includes firing metallic scrap in a shotgun-like blast. On top of that, it can also act as a pulse rifle with infinite ammo, and can be upgraded to add a cryogenic or electrical effect to any shot it fires.

** ''Film/Solo'' has the DL-44 heavy blaster pistol that can transform from a blaster pistol into a blaster rifle by attacking a stock and extended barrel.
** ''Film/RogueOne'', has the A-180 blaster pistol and A280-CFE convertible heavy blaster pistol that can turn from a pistol to a rifle. The A-300 blaster rifle is a unique one that transforms from a blaster carbine to a rifle.

* ''Project Clean Earth'' has the robot Bernard cleansing the Earth of hostile mutants. His main weapon is a longarm that always starts with a pistol but with the right modules it can then add a rifle, minigun, shotgun and sniper rifle. He fires all these simultaneously though because differing rates of fire there might be different bullet streams coming out. Bernard needs all these guns on one weapon because he doesn’t have many weapon slots, with the other main slot being reserved for Bernard's RocketPunch weapon.

* 10tons's ''VideoGame/{{Jydge}}'' features a character who's a mashup of ComicBook/JudgeDredd and Film/{{Robocop}}. So it's fitting that its gun, the Gavel [=Mk1=] is the unholy offspring of a futuristic lever-action carbine, the [=FN SCAR=] and a steel sledgehammer. This makes it a gun that's awfully good at smashing skulls. The Gavel [=Mk1=] has different firing modes that not only turns it to a shotgun or assault rifle, etc. with unlimited ammo (but still needs reloading), but also lets it fire lasers, plasma and ion bolts as well. The Gavel [=Mk1=] can add a special weapon that lets it fire a limited number of rockets or [[StarfishRobot spider drones]] and other things. It can also house up to 3 different mods giving the gun abilities such as recovering health from killing and giving your gun better rapid-fire. The only drawback to the Gavel is that it can only switch out its settings when not on a mission.

* In ''Film/{{Blastfighter}}'', Pete gives Tiger an untraceable high-tech shotgun. It has an interchangeable rifle barrel, can fire rifle grenades (including tear gas), and comes with a variety of ammo, including, high explosive, incendiary, and amour-piercing. Needless to say, all of its functions get a workout during Tiger's LastStand.

* In Videogame/StarWarsTheOldRepublic the Republic Trooper class (no matter the Advanced Class choice) has this as a weapon. It can fire regular shots, an "explosive round", fire mortars, lay down a close AOE Ion Pulse, and can [[HealingShiv heal teammates]].

* 2012's ''Film/{{Dredd}}'' features the same Lawgiver as ''Film/JudgeDredd'' below, with its trademark [[CallingYourAttacks voice-selectable ammunition]]. Known bullet types are: standard-which can be customized for [[MoreDakka rapid fire]] or [[HollywoodSilencer silenced]], stun rounds, [[KillItWithFire Hot Shot]], Incendiary (a long distance white phosphorous like scatter shot), Armor Piercing, and [[StuffBlowingUp High Ex]].

* Parodied in ''WebAnimation/HomestarRunner'''s ''[[StylisticSuck Dangeresque]]'' movies. The titular AntiHero's WeaponOfChoice is the Nunchuk-Gun, which is basically a [[RevolversAreJustBetter revolver]] with a pair of nunchuks [[DuctTapeForEverything taped to it]].

* Every weapon in ''VideoGameDoomEternal DOOM: Eternal'' has two alt-fire functions, which the Doomguy can choose between by swapping out the barrel of the gun. Some of them simply increase the firepower of the primary fire via increasing damage or firing speed, but others have entirely separate weapons included:

** This is actually OlderThanTheyThink, as the Steyr AUG and [[RareGuns the Stoner 63]] were designed with this kind of functionality. The Steyr can even be converted to an SMG.

* ''Videogame/GunmanChronicles'' is made of this trope. It has little more than 6 actual weapons, but each weapon has at least 4 submodes, that can even have their own ''sub-sobmodes'': you can program a Rocket Launcher for firing homing or non homing missles, and sub-program said missles to be high explosive, grapeshot, or attach to the surface as laserwire high explosive/grapeshot mines.

* Similar to {{Grenade Launcher}}s and {{Shotguns|AreJustBetter}} above, {{Revolvers|AreJustBetter}} are also sometimes put into this category because the "random access" of their cylinders can more easily accept situational specialized ammunition by loading individual rounds than a magazine or belt-fed automatic weapon would use.

** You think the standard SpaceMarine is scary with his automatic-explosive-armor-piercing-round firing "Bolter", don't you? Say hello then to the Sternguard Veteran, whose guns can switch between '''multiple''' specialized bolter ammunition types depending on the situation, be they incendiary-fireball-explosive, scalding-gas-explosive, supersonic-velocity, extra-armor-piercing or scariest of all, ''poisonous-acid-filled'' bolts.

** The tabletop game has rules for combi-weapons, basically a weapon with a different weapon attached and can be used once per game. When they debuted in the ''Slaves of Darkness'' supplement for Khorne and Slaanesh, a combi-weapon with two different guns was the bare minimum (a character could have a combi-weapon with many more guns than just two) and combi-weapons could be used as many time as you wish.

* ''VideoGame/{{Redline}}'' features such a weapon wielded by the protagonist. Besides the standard assault rifle mode, it can also become a [[ChainsawGood buzzsaw]] (with optional nitro upgrade that makes you fly around for a limited time), a rocket launcher, an EMP device (handy for those vehicles!), a shotgun, a grenade launcher, an alien goo shooter, a sniper rifle, and a {{hitscan}} plasma beam weapon.
