The Colt Mk IV Series 70 appears to be the dominant M1911 variant of the season. The Colt Mk IV used in this season is a live gun and it is shot for real multiple times during the season.
In "The Golden Triangle" (S1E02), a goon in a junkyard carries an Colt Mk IV Series 70 with a supressor during the episode's "opening gambit". Later, when the real episode starts in Burma, it is used by the villianous Truang (Benjamin Lum), Gen. Narai's right hand man. It's mostly seen in his holster, but he draws it out when MacGyver starts causing commotion in the camp. He loses it when MacGyver rams a truck to a shed he is hiding in. When Truang's envoy returns to the village, he has aquired a new one. When MacGyver stops the envoy to taunt them, Truang pulls his Colt and shoots at MacGyver. The Colt Truang fires a real one, as it ejects casings and gunsmoke. Truang has the Colt Mk IV out for rest of the guerilla combat scene, until he is disarmed by Ming's (James Saito) bamboo pole kung fu.
In "The Gauntlet" (S1E04), during the opening gambit a high-ranking enemy officer wields a M1911 with chrome ejection port. The M1911 seems to alter between a real one and a non-firing prop, between one with a chrome-colored ejection port and one with a black one. In the main part of the episode, General Vasquez (Gregory Sierra) carries one. It's mostly kept in a holster, but when MacGyver sets off distraction near a church, he draws his Colt Mk IV out of his holster. Also one of Gen. Vasquez's men are seen with a Colt Mk IV.
In "The Heist" (S1E05), a Colt Mk IV appears appears in hands of Jack Catlin (Vernon Wells) at the very beginning, when he rubs off Daniel Sims (Larry D. Mann) with one. The Colt Mk IV is a real gun and actor Vernon Wells is made to shoot it for real. He has trouble keeping face while shooting it and goes through many goofy expressions during the short scene where he fires the gun. One appears in holster of one of the soldiers at airport at the beginning and the end of the episode.
In "Last Stand" (S1E07), Colt Mk IV first appears tucked in Elias' (Anthony Pena) pants. After MacGyver starts causing havoc with MacGyver'ed fertilizer bombs, Elias gets out the Colt Mk IV and goes to investigate. After MacGyver and the hostages try to flee with a water truck, Elias and the boss Terry Andrews (Michael McGuire) board the car. With Elias on the wheel, Terry takes the Colt Mk IV and starts shooting at the escapees. Terry Andrews carries the Colt Mk IV for the rest of the episode, while Elias gets a H&K P9S.
In "Target MacGyver" (S1E10), one of Axminster's goons appears briefly to have the Colt Mk IV.
In "Nightmares" (S1E11), it's carried by goon named Polk (Tommy Lamey). His M1911 has chrome ejection port, meaning this is the Colt Mk IV that pops up a lot in this season. Also the Colt Mk IV emblem is visible in one scene.
In "Flame's End" (S1E13), it's carried by Police Chief Ed Train (Conlan Carter), who turns out to be one of the two people involved in the uranium theft. He reveals himself with Colt Mk IV in hand and tries to kill Mac, Amy and a security guard to erase witnesses. However, Tim Wexler (Robert Englund) leaps in and is shot in the stomach. Train starts to fire towards Mac and Amy, ending up destroying plant controls and injuring the security guard. Again, the gun is shown recoiling. Also, as with Vernon Wells in Episode 5, the actor here seems nervous handling the gun. Train fires 'till he runs out of ammo and flees after that.
In "The Enemy Within " (S1E15), it is used by the brainwashed Craig Bannister (Michael Goodwin) in the episode finale.
Other M1911
While Colt Mk IV Series 70 appears to be the dominant M1911 variant of the season, there are some other M1911 appearing in this season as well.
In "The Gauntlet" (S1E04), the high-ranking enemy officer's M1911 alters between a this M1911 variant and a Colt Mk IV. The pistol is possibly a non-firing prop pistol. It's distinguishable from the black barrel/ejection port.
Star Model BM
In "Golden Triangle" (S1E02), a nickel, pearl-grip Star Model BM is the sidearm of General Narai (George Cheung). It's seen holstered in his earlier scenes. When MacGyver forces his copter to land, he draws this pistol. However, once he gets out of the helicopter, he is immediately disarmed by MacGyver's hi-keeba move, forcing the two go hand-to-hand. After Gen. Narai dies, MacGyver (Richard Dean Anderson) picks the general's gun up.
Walther PP
Walther PP has multiple appearances during this season. Notably it appears to be Peter Thorthon's (Dana Elcar) sidearm through the season and wields it in numerous occassions.

Raven Arms MP-25
Appears in "The Heist" (S1E05). After diamond heist, Chris Rhodes (Doran Clark) gets caught by Jack Catlin (Vernon Wells) and the latter uses the former to force MacGyver to return his diamonds. MacGyver driving a MG MGB with the diamonds in the back trunk meets the henchwench Tiffany (Victoria Bass), who enters the car and draws a Raven Arms MP-25 on MacGyver and guides Mac to Chris' location. At the airport, she keeps the gun trained on MacGyver.
Heckler & Koch P9S
Both the pre-'73 and post-'73 models of the Heckler & Koch P9S appear multiple times during this season. In the early seasons (that is 1-3) of original MacGyver, it appears quite frequently as the gun of choice of most villains and their underlings. When the production moves to Canada for later seasons, the Taurus PT92 and/or Beretta 92F become the dominant bad guy guns.
In "Last Stand" (S1E07), after getting the money out of the armored car, a P9S appears on the desk when the badguys are counting the money. After MacGyver's escape fails about midway thru the episode, a goon named Elias (Anthony Pena) starts using it. Elias carried a Colt Mk IV earlier in the episode, but during a car chase, he gave the Colt to his boss, Terry, who pretty much overtook the gun for himself.
In "Nightmares" (S1E11) - both P9 variants appear. A pre-'73 model with a suppressor attached is used Barrett (J.P Bumstead). The post-'73 model appears in hands of Colonel Curt Neilson (Robert O'Reilly), who gets the P9S out in the finale after MacGyver takes out the remaining two goons. Curt ends up losing the P9S when he and MacGyver end up grappling on ground.
In "The Enemy Within " (S1E15), Reverend Mather (Douglas Dirkson) uncovers a pre-'73 P9S under cloth beneath the podium desk when the GRU assassin Anton Lem (Beau Starr) activates the Reverend's brainwashing during his speech. It turns into Heckler & Koch VP70 due to continuity error.
In "To Be A Man" (S1E17), villainous Khalil (Sid Haig) wields a post-'73 P9S. After Khalil is downed, young boy Ahmed (Ajay Naidu) tries to give the P9S to MacGyver to finish Khalil off.
Heckler & Koch P7
Heckler & Koch P7 appears in the episode "The Prodigal" (S1E09). At the beginning, mafia goons take Frank Bennett (Robert Romanus) to a woodshop, where he meets his brother, Joey Bennett (Richard Romanus, actually Robert Romanus' brother). Joey intends to silence his brother and orders a goon named Max (Stan Kamber) to give him a gun. Max draws a H&K P7 (judging from markings, it's one of early 80's "Arlington, VA" import P7s) from a shoulder holster and gives it to Joey. After MacGyver causes a distraction and gets Frank to safety, Joey throws the gun back to Max and boards the car to chase MacGyver.
In the last part of the episode - at Bennet Family Home - after Frank tells Joey that their mother died, Joey only remarks that he will "miss her, as he is going to miss [Joey]" and Max draws the P7 and escorts Frank to a place to shoot him. However, MacGyver uses a string and rod to trip Joey and Max on stairs, allowing Frank to escape. Max shoots at the escapees but misses.
"The Enemy Within " (S1E15). When Reverend Mather's (Douglas Dirkson) brainwashing kicks in, he unveils a gun concealed in cloth under the podium desk. First the gun is a pre-'73 Heckler & Koch P9S, but when the Reverend reveals the gun to the event attendees, it has turned into Heckler & Koch VP70. Reverend loads the gun and starts to fire at the crowd at seemingly random. It later appears in the hands of the GRU assassin Anton Lem (Beau Starr) in the episode finale. He loses the gun when MacGyver pushes a TV stand at him. MacGyver picks the gun up and puts it aside. The gun appears to be real, as when the reverend fires it, it ejects a casing, exhalts large muzzle blast and the barrel is smoking after shooting it.
In "Ugly Duckling" (S1E18), a goon named Larkin (Ned Bellamy) has VP70 with a supressor attached. He first uses it during the botched attempt to abduct the Professor Willis (Richard McKenzie). He is seen with the pistol out while talking to his boss, Hatcher (Lee de Broux). He notably wields it during a action scene in a computer class, trying to capture Kate Lafferty (Darcy Marta). He pistolwhips MacGyver uncouncious with it.
Browning Hi-Power
Appears in "Target MacGyver" (S1E10), one of Axminster's men loads a Browning Hi-Power before attacking Harry Jackson's (John Anderson, unrelated to Richard Dean Anderson) cabin. The Hi-Power is not used for remainder of the episode, as the Axminster's goons carry Type 56 rifles for all times.

He keeps MacGyver and Dr. Marlowe at bay while the group discusses about Dr. Steubens' motives. Rashly acting Barbara Spencer (Darlanne Fluegel) rushes at Steubens and tries to wrestle the gun away, but the gun goes off and Barbara gets shot. Startled Steubens drops his guard and MacGyver uses the chance to disarm him.
In "The Last Stand" (S1E07), Security guard that was stuck in a armored car has one. However, he is shot by Buddy (Lewis Van Bergen) before he can use it to defend himself. It's seemingly used by Turk (Jackie Earle Haley) after he loses his first gun.

Smith & Wesson Model 28 appears in "Flame's End" (S1E13). It first appears in last quarter of the episode; after MacGyver and Amy Austin (Tannis G. Montgomery) find the hidden uranium, Tim Wexler (Robert Englund) confronts the two with a Magnum on hand. However, MacGyver tells Tim that the latter doesn't have courage to shoot them. Despite Tim threathening to shoot MacGyver and Amy, Mac's guesses right and Tim is unable to shoot and drops the gun in grief. Later, after Police Chief Ed Train (Conlan Carter) is revealed to be a partner-in-crime, he grabs the S&W dropped by Tim after his Colt runs dry. Train tries to shoot MacGyver with it.

In this episode, the Ithaca 37 is subject of a infamous MacGyverism where MacGyver uses sun-beam projection to heat up the Ithaca 37's bottom ejection/loading port, causing the chambered shotgun shell to go off and cause a disproportionately big explosion.
Rifles and Carbines
Valmet M71S
In "Pilot" (S1E01), Central Asian soldiers as well as MacGyver (Richard Dean Anderson) are seen using the Valmet M71S, standing in for the AK-47. All of these rifles appear to have 30-round .223 pre-ban metal magazines. Based on the shape of the stock, these are plastic handguard/resin-stock variants.
Norinco Type 56
Norinco Type 56 rifles also appear in the series. Frequently the Type 56 appears with a AKM-style slant cut muzzle break, presumably to pass off as a AKM, yet the trademark Type 56 front sight is often visible on them. Ocassionally, there are Type 56 without the slant-cut muzzle break. This rifle usually appears when a character within the episode needs to fire a live AK-type rifle on screen, as there is muzzle flash and ejecting casings coming from this rifle.
In "Pilot" (S1E01), MacGyver (Richard Dean Anderson) goes to seek a missile that's hidden in a tent, a noticeable continuity error occurs, as the Valmet M71 he carried in the previous scene has changed to an AKM. He later uses the AKM as part of a MacGyver'ed distraction to allow MacGyver to get the captured fighter pilot escape from a cage. Most peculiarly, MacGyver - who is later established as a very anti-gun person - opens fire towards chasing soldiers to fend them off; the reason for the uncharacteristically casual way he handles firearms in the pilot episode is exactly because this is the pilot episode. So details like MacGyver's backstory and aversion of firearms were merely in flux, depending on whatever the show would get picked up by a tv network or not. He later gives the AKM to prisoner while he starts to work on the escape plan.
In "Golden Triangle" (S1E02), the rifle appears in hands of one the villagers when they prepare for Gen. Narai's counterattack as evidenced by the full-scooped hood on it. Live-firing variants are seen in a trap the villagers rig. Which, instead of horribly mauling the Burmese soldiers, it just blows the tires of all their jeeps.
In "Thief of Budapest" (S1E03), Type 56 rifles appear in the hands of Hungarian prison guards. Once riot starts, a one is stolen by a prisoner. When MacGyver and gang make a escape with a van, bunch of soldiers are shown to fire live Type 56 rifles. Even though they fire real guns, it's just trick photography exploting angle cuts.
In "Gauntlet" (S1E04), the rifles are wielded by Arabic soldiers in the episode's opening gambit. One soldier fires a live Type 56 on screen.
In "Target MacGyver" (S1E10), Type 56 rifles are used by Axminster (D'Mitch Davis) and his underlings through-out the whole episode. In finale, they use trick photography to fool the viewer into thinking that Type 56 firing in full auto.
In "Deathlock" (S1E12), during the opening gambit, when plan to smuggle MacGyver out of East Germany goes sour, the border guards with Type 56 move out. They are seen firing their Type 56 rifles at MacGyver on his coffin jetski.

In "The Golden Triangle" (S1E02), Burmese Soldiers under General Narai have AK-47(s) with open hood sights. It's later seen in hands of the villagers after they prepare against Gen. Narai's retribution, though MacGyver proposes non-lethal approach. Gerald Okamura has a small cameo role as one of the Burmese soldiers.
In "Thief of Budapest" (S1E03), the rifle appears in the hands of Hungarian prison guards. Notably a Fat jerk soldier clearly has a Type III AK-47.
In "Deathlock" (S1E12)" - if the lifted footage from Funeral in Berlin is anything to go by, this one border guard has a fixed stock AK-47 the opening gambit.
In "Every Time She Smiles" (S1E16), it is wielded by Bulgarian Militsiya when they enter the Airport with Major Stepan Frolov (Kai Wulff) to confront Penny Parker (Teri Hatcher) over the diamonds.

First seen hiding it behind the corner when MacGyver first arrives to airport diner. He enters the diner and after MacGyver spots a "Help" message on his coffee cup, Buddy draws his M16 on MacGyver. For the diner scene, he uses the M16 to harass the hostages. When the armored car arrives, Terry Andrews (Michael McGuire) takes Buddy's M16 for a while. After getting the armored car open, Buddy uses his M16 to shoot the security guard who was stuck inside. Buddy has the M16 while chasing MacGyver and hostages trying to escape with water truck on a motorcycle. He takes Kelly Nielson (Kay Lenz) hostage with it. He brings out M16 again in the finale. After Buddy is disarmed by MacGyver, the latter uses the M16 as a melee weapon to knock out Buddy. MacGyver gives the M16 to Dave Redding (Art Hindle) and then chef Al Tennyson (Harry Caesar) takes it over.

Browning M1919
Browning M1919 - in many different variations - has multiple appearances.
Two significant versions of M1919 appear in the episode "The Golden Triangle" (S1E02). First, General Narai's (George Cheung) men found two Browning M1919(s) - with flexible mounts and early slotted barrel shrouds - from a downed aircraft. Narai's men install these to these the General's helicopter. At the episode's climax, General attacks the villagers with the machine gun armed helicopter. These are presumably mock-up props, as the reciever lacks details. Also the gunfire is obvious pyrotechnics. Actual A4 variant appears in the last quarter of the episode on the jeeps of the Burmese soldiers.
Browning M2
Browning M2 appears in "The Gauntlet" (S1E04). It has been installed on jeeps of the soldiers under Gen. Vasquez. These are real M2 machine guns, as at the episode's finale, they are shown firing for real, with empty shells and brass ejecting from it.

Judging by the boxy appearance of the launcher body with only small rounded-off sections at the corners, this is probalbly either the same prop launcher used by Arnold Schwarzenegger in Commando or a replica of it. It disappears in next scene and is replaced by an M60 (the prop M202 FLASH was probably removed to protect it from the pyrotechnics that occur around the table).
FIM-43 Redeye
In "The Gauntlet" (S1E04), Dave Ryerson (John Vernon) is selling black market US surplus weapons to Gen. Vasquez (Gregory Sierra), amongst them is an FIM-43 Redeye.

"Snake-Eye Missile"
Featured in episode "Ugly Duckling" (S1E18) is a fictional "Snake-Eye Missile", which is described as an defective American surface-to-air heatseeker missile system with excess number of these missiles on surplus.

BONUS: Lifted footage
Season 1 of MacGyver is little notorious for its stock footage lifted from previous motion pictures. The majority of the lifted footage was from films released by Paramount Pictures, as MacGyver was also Paramount production.
In "Thief of Budapest" (S1E03), the footage from the original 1969 film The Italian Job was used of the three Mini Coopers racing from the police in Italy. Almost everyone who has seen this show knows about this one instance of lifted footage.
In "The Heist" (S1E05), MacGyver's MGB car parachuting out of the back of a cargo plane was actually from a mid 80's TV commercial for the British Leyland Motors MG Car Company.
In "Trumbo's World" (S1E06), much of the plot as well as the footage is taken from The Naked Jungle (1954), notably footage of Christopher Leiningen (Charlton Heston) flooding the ants out in the field.
In "Target MacGyver" (S1E10), when MacGyver is seen blowing up a reactor plant at night, the actual explosions were taken from the film Tobruk (1967).
In "Deathlock" (S1E12), the footage of the East German border guards was taken from the Michael Caine film Funeral in Berlin (1966).
