Pistols

SIG-Sauer P226

After carrying a Smith & Wesson 5906 in Season 3, FBI Special Agent Fox Mulder (David Duchovny) returns to carrying a SIG-Sauer P226 as his sidearm, which he carried during Season 2. Mulder would carry the P226 for the entirety of the show from Season 4 onwards. Mulder's superior, FBI Assistant Director Walter Skinner (Mitch Pileggi) is also seen with a full-size P226 in "Unrequited" (S4E16).

SIG-Sauer P228

After carrying a Smith & Wesson 5906 in Season 3, FBI Special Agent Dana Scully (Gillian Anderson) returns to carrying a SIG-Sauer P228 as her sidearm, which she carried during Season 2. Scully would carry the P228 for the entirety of the show from Season 4 onwards, except for several episodes in Season 4 (as well as Season 5) when she used a SIG-Sauer P225 instead (see below). Mulder and Scully's superior, FBI Assistant Director Walter Skinner (Mitch Pileggi) is also seen with a P228 in "Zero Sum" (S4E21). Alex Krycek (Nicholas Lea) is seen surrendering a SIG P228 with suppressor in "Tunguska" (S4E08). Other FBI and government agents on the show are also seen using P228s.

SIG-Sauer P225

In several episodes, Dana Scully used a SIG-Sauer P225 rather than the P228 she used in Season 2. This might have occurred because the show's armorer was unable to bring a P228 on-set for those particular episodes. Scully first used the P225 in "Home" (S4E02), and would be seen using the weapon in interspersed episodes throughout Season 4 and Season 5. Mulder and Scully's superior, Assistant Director Walter Skinner (Mitch Pileggi) also occasionally carried a P225 rather than a P228.

Special Agent Dana Scully (Gillian Anderson) draws a SIG-Sauer P225 in "Home" (S4E02). This is the first time in the show she is seen with a P225 instead of the SIG-Sauer P228 she previously carried.

Smith & Wesson 5906

Special Agent Dana Scully (Gillian Anderson) is seen wielding the Smith & Wesson 5906 handgun that she used in Season 3 in the Season 4 premier episode "Herrenvolk" (S4E01). Special Agent Fox Mulder (David Duchovny) and Assistant Director Walter Skinner (Mitch Pileggi) are also seen with their S&W 5906s from Season 3 in "Herrenvolk" (S4E01). These are the same weapons from the previous season, with their particular features - Rounded trigger guard, adjustable sights, and black (blued-steel) triggers and hammers. A Syndicate operative is briefly seen holstering a 5906, also in "Herrenvolk".

Special Agent Scully (Gillian Anderson) holds the Smith & Wesson 5906 at the beginning of the season premiere "Herrenvolk" (S4E01). This was also shown at the conclusion of the previous season finale "Talitha Cumi" (S3E24).

Beretta 92FS pistols are seen numerous times throughout the series, carried and used by police officers and government agents, as well as soldiers and military personnel as a Beretta M9 substitute.

In "Terma" (S4E09), a number of Russian guards are seen armed with what appear to be Makarov PM handguns. Several of these guards use these from horseback as they pursue Mulder as he escapes the Tunguska gulag.

Smith & Wesson Model 10

In a dream during "Paper Hearts" (S4E10), Fox Mulder grabs his father's Smith & Wesson Model 10 revolver from a box. This is the same revolver he attempted to use to save his sister Samantha from alien abduction as a child, seen briefly in a flashback in the Season 2 premiere episode "Little Green Men" (S2E01).

Taurus Model 66

Conrad Lozano (Rubén Blades) carries a stainless Taurus Model 66 in "El Mundo Gira" (S4E11). Soledad Buente (Jose Yenque) also uses the revolver at one point. This is almost surely the same Taurus Model 66 which previously appeared in the Season 3 episode "Pusher" (S3E17).

Rifles

Colt Model 715/Olympic Arms K4B (mocked up as M16A1)

Militia gunmen and several FBI tactical agents in the episode "Tunguska" (S4E08) use Colt Model 715 rifles (or the Olympic Arms K4B copy, which is commonly used by armorers in British Columbia) fitted with M16A1 hand guards. Apparently, the armorers had no genuine M16A1s to use when the episode was filmed.

Colt Model 715 (virtually identical rifle to the Colt Canada C7) - 5.56x45mm

Olmypic Arms K4B - 5.56x45mm. This rifle is very similar to the above Colt Model 715, but is distinguished by the "Stowaway" pistol grip, a feature often found on Olympic Arms AR-15 rifles made in the 1990s. Rifles similar to this one are frequently seen in productions filmed in British Columbia.

A closer view of the M16's barrel in "Tunguska" (S4E08), showing that it is a heavy A2-style barrel, although the rifle is fitted with M16A1 hand guards and meant to pass for an M16A1. Also note that the rifle is missing the forward sling loop under the front sight for some reason (it may have broken off during a stunt).

Colt Commando

Several episodes in Season 4 feature Colt "Commando"-type carbines, usually in the hands of military personnel and SWAT officers. None are seen very closely, but they appear to be the same A1E1-receiver short barrel carbines seen throughout the first season.

Colt Model 733 (11.5" barrel 'M16A1 Carbine') - 5.56x45mm

XM177 (mock-ups)

XM177-type carbines are seen used by military personnel and SWAT officers, notably FBI tactical agents conducting a raid in "Tunguska" (S4E08). These appear to be the same weapons from Season 3 - All of them seem to be mocked up from other various AR-15 carbines (some have SP1 upper receivers, others have A1-style, and still others have the A1E1 style), as per the norm with XM177s in the vast majority of films and television.

M14

M14 rifles are used by members of the Temple of the Seven Stars in "The Field Where I Died" (S4E05). Another M14 is used by a militia gunman in "Tunguska" (S4E08).

Norinco Type 84S

Two Norinco Type 84S rifles are seen in the episode "Terma" (S4E09), used by guards at the Tunguska gulag. One appears to be a standard Type 84 while the other appears to be a long-barrel 'Match' variant with folding stock. It is interesting that only two Russian soldiers were seen armed with AK rifles while the rest of the unit were armed with clubs/nightsticks (though several of the guards are later seen with Makarov PM pistols). There is a possibility that there were not many AK rifles available in Vancouver during the mid-1990s, which could explain why only two gulag guards were armed with rifles while the others were armed with nightsticks.

The Cigarette-Smoking Man's Rifles

The 'Cigarette-Smoking Man' is seen wielding three rifles during "Musings of a Cigarette-Smoking Man" (S4E07).

Remington 742

The first rifle used by the younger Cigarette Smoking Man (Chris Owens) is a short-barreled semi-automatic Remington 742. The rifle has a 'take-down' type of folding stock, and is fitted with a brass catcher. He uses it to assassinate President John F. Kennedy.

The second rifle wielded by the younger Cigarette Smoking Man (Chris Owens) is a pump-action Remington Model 760 rifle fitted with a scope. He uses this rifle to assassinate Martin Luther King Jr.

Ruger Super Redhawk (mocked up to resemble the KAC silent revolver rifle)

The third rifle, used by the present-day Cigarette Smoking Man (William B. Davis), is what appears to be a Ruger Super Redhawk .44 Magnum mocked up to resemble the KAC silent revolver rifle. This is a long barreled pistol has a carbine length bull barrel, and a bipod and black synthetic buttstock. The rifle has appeared in movies and television shows filmed in Canada including Another Stakeout and Psych.

Submachine Guns

Heckler & Koch MP5A3

Numerous Heckler & Koch MP5A3s are seen throughout the series. These are wielded primarily by black-ops soldiers and operatives. Special Agent Dana Scully (Gillian Anderson) notably uses a Heckler & Koch MP5A3 with Surefire 628 flashlight forearm during the FBI raid on the militia in "Tunguska" (S4E08). Other FBI tactical agents are seen with MP5A3s as well. Unlike in previous seasons of The X-Files, the MP5s are no longer fitted with flash hiders in Season 4.

(Mock-up) Heckler & Koch MP5K

What appear to be Heckler & Koch MP5Ks are seen used by government and military personnel. These do not appear to be real MP5Ks; but rather mock-ups built on the bolt carrier and magazine well of a Kimel AP-9, because the armorers in British Columbia did not have genuine MP5Ks during the 1990s. The same guns have also appeared in the film Crying Freeman and the series M.A.N.T.I.S. and The Outer Limits. These weapons are notably seen wielded by ATF SRT agents in "The Field Where I Died" (S4E05) and FBI tactical agents in "Tunguska" (S4E08).

Ithaca 37 "Stakeout"

A custom Ithaca 37 "Stakeout" with a chrome finish on the barrel and magazine tube and an MP5K style pump is used by Scott Ostelhoff in the season finale "Gethsemane" (S4E24). This gun can also be seen in several episodes of the television series Supernatural, Human Target, Painkiller Jane, and several other TV shows filmed in British Columbia.
