Firefly was a science fiction series that aired for one season from 2002-2003 on the FOX network. Created by Joss Whedon, the series starred Nathan Fillion as the captain of a firefly class spaceship known as "Serenity", whose crew travels through a distant solar system making a rough living on frontier planets while fighting various adversaries. The series mixed the "space opera" genre with certain elements of the Western, thus the mix of American Western weaponry with the more modern firepower. The series' plot would continue in the 2005 feature film Serenity.
The following guns were used in the television series Firefly:
The signature pistol of Captain Malcolm Reynolds (Nathan Fillion) in the series is a Taurus Model 85 revolver completely covered by a brass casting to make it resemble a semi-auto handgun. The look of the weapon was based on the Volcanic repeaters used in the Civil War as explained by Firefly creator Joss Whedon in the visual companion book of the series. In the Firefly universe, the gun is a "Moses Brothers Self-Defense Engine Frontier Model B". The same prop gun was used for the feature Serenity, but given to a new prop house who made the magazine straight on the bottom, and bulked up the right side plate and added a spring loaded rear sight. It was then held by Fillion in his current series Castle.
LeMat Revolver
Jayne Cobb (Adam Baldwin) also carries a custom sidearm, which is a visually modified single-action LeMat Revolver.
Astra 400
Lawrence Dobson, an Alliance Spy that comes onto Serenity, carries an Astra 400.
Beretta 92FS
A reverse two tone Beretta 92FS was seen in the hands of an Alliance officer in Bushwacked.
In Objects in Space, River gets hold of a nickel-plated Desert Eagle Mark VII, fully loaded and safety off, but no round chambered as Mal had confirmed. It was never fully explained how she obtained it, as it was supposedly locked in Jayne's (Adam Baldwin) room.
Ruger Mk II Pistol
A Ruger Mk II Pistol is used by Inara in the episode Trash, only when Saffron (Christina Hendricks) is rifling through the trash for the Lasiter, which Inara has. Malcolm was also seen preparing one in Heart of Gold.
Note of interest. In the original teleplay, Inara's gun was originally called a "Lugar".

A Glock 17 is seen in the hands of an angry drinker and a corrupt cop. Simon carries the Glock 17L variant with a optics rail and an under-barrel laser-sight attached to it during the assault on the Skyplex.
SIG-Sauer P220 Sport
Lawrence Dobson gets a SIG-Sauer P220 Sport out from his bag after he knocks out Book, which is used to threaten both Kaylee and River. Jayne (Adam Baldwin) either has an identical pistol in his room or stole it from him after the pilot.
Smith & Wesson Model 15
A Smith & Wesson Model 15 is seen in Heart of Gold, this ornate, gold-plated revolver with ivory grips was Nandi's favorite gun, who said it had a history of "violence and crime." At the end of the episode, Petaline uses it to kill Rance Burgess, the father of her child and Nandi's killer.

In the episode The Message, Mal and Zoe's old war buddy Tracey sees a Heckler & Koch VP70 on the bridge and uses it to hold off the crew.
SIG-Sauer P229

In the battle of Serenity Valley, The 'Browncoats' carry Heckler & Koch G36K rifles.
L85A1
During the battle of Serenity Valley, and across the episodes, such as The Train Job the Alliance Soldiers carry L85A1 rifles. A few are also seen in the hands of Browncoats in war sequences, most notably Bendis in the Serenity Valley scene.
In the pilot, the Blaser R93 LRS2 Sniper rifle is held by a sniper at the meeting on Whitefall, who Jayne Cobb knocks out and uses the rifle against Patience's men (starting with Two-Fry's hat). They were also seen use by the team that kidnapped Mal and Wash in "War Stories", where they are referred to as "54R" sniper rifles.
AKMSU
The AKMSU is seen in the Episode Heart of Gold By one of Burgess' soldiers.
Flux Colt XM177E2
The Flux Colt XM177E2 shown has A2 sights, a delta ring retaining the hand guards, A2 reinforcements on the lower, a 5.5" flash suppressor, and a round forward assist so it's not the 1960's vintage XM carbine in the title but closer to a cobbled together '90s carbine like this one.
AKM
An AKM is carried by Burgess's horseback riding henchmen in episode Heart of Gold.
AKU-94
An AK variant is encased in the KVAR AKU-94 bullpup stock, held by one of Niska's men in "War Stories"

FAMAS-223
The FAMAS-223 is seen in the hands of Malcom during the battle of Serenity valley. He then drops it and picks up a G36K to capture an AA gun. Zoe in a scene also carried a FAMAS but it changed to a G36K when she started shooting. The rifle is the Civilian version of the FAMAS, imported briefly into the U.S. as the Semiautomatic FAMAS-223. It is virtually identical to the military FAMAS except for the lack of a full auto switch position and the barrel is not ridged (to take rifle grenades). The smooth outer barrel was an ATF requirement to be imported into the country. Soon after, the ATF declared all foreign "bullpup" rifles to be unsporting and banned their import. This was done years prior to the 1989 import ban.
Henry 1860 Rifle
A Henry 1860 Rifle is held by a woman in an episode.
Marlin Model 1895 Lever Action Rifle
Marlin Model 1895 Lever Action Rifles are used by Nandi and Mal in the episode "Heart of Gold".

Shotguns
Callahan Fullbore Autolock "Vera"
A Modified Izhmash Saiga-12 shotgun used by Jayne (Adam Baldwin). The weapon was built by Gunsmiths Larry Zanoff and the late Jim Boland for the movie Showtime then used on Firefly. It is capable of folding into compact form and still be fireable. Technically it's a shotgun, but in the show, it is a rifle that fires big bullets. In the episode "Our Mrs. Reynolds", Vera requires oxygen to fire, which could be explained if it used an ignition system like the Daisy VL caseless .22 rifle (1968-1969).
Double Barrel Shotgun
Benelli M3 Super 90
Patience was seen using a Benelli M3 Super 90 shotgun with a pistol grip and without any sights. The barrel is also cut down.

M60D
An M60D is mounted on a hover craft in the episode "Heart of Gold".
Ruger MkIII, Jericho 941 w/ a stainless finish, some FABARM shotgun, I think that the closest handgun is a Springfield XD, one of his many shotguns is a Winchester 1300.
The farthest gun, based on the muzzle break thing looks like VERA to me. The closest gun, to me, looks like a Ruger semi-auto. A p-89 maybe. I also see a Ithaca stakeout with a pistol grip in there.
Wildey Magnum, a Mossberg Persuader of some sort, A Blaser R93, 37mm Tru-Flite Police Tear Gas Gun appears again in the centre, I think I see a Smith and Wesson 629 Performance Center model,
