Season 4: Christopher Moltisanti (Michael Imperioli) shoots Det. Lt. Barry Haydu (Tom Mason) with Haydu's own police-issue Glock 19, then plants the Glock in Haydu's hand to make it look like suicide in For All Debts Public and Private (4.01).
Season 6: Eugene Pontecorvo (Robert Funaro) uses a Glock when Christopher assigns him to the assassination in Members Only (6.01).

(IMFDB thanks The Golden Closet for providing the documentation on this gun, as well as the image seen below.)

Paulie (Tony Sirico) uses a SIG-Sauer P228 with a suppressor in A Hit is a Hit. Tony Soprano (James Gandolfini) takes another P228 out of his ceiling during the indictments in The Legend of Tennessee Moltisanti (1.08), hiding it in a hat box at his mother's nursing home apartment. Mikey Palmice (Al Sapienza) uses a P228 to kill Donnie Paduana inside his car in Isabella (1.12). In that same episode, Rasheen Ray (Touche) uses a P228 to try and kill Tony, later causing him to lament about the incident: "Two pricks with nine millimeters... my self-esteem is non-existant right now", referring to Ray's P228 and his partner's Glock 19.

Jimmy seems to have a knack for keeping .357 revolvers in his ankle holster, as an FBI agent removed a Smith & Wesson Model 13 from an ankle holster two episodes previously. It is only seen briefly but the grips and the cylinder give it away as an SP101.
Ruger Speed Six Snub
Christopher (Michael Imperioli) uses a snubnose Ruger Speed Six when robbing a college benefit concert with Jackie Aprile Jr. in Fortunate Son (3.03). In a 1982 flashback, a young Tony Soprano uses a snubnose Ruger Speed Six to commit his first murder, a bookie named Willie Overall (Herbert Rogers) in Remember When (6.15).

Jackie Aprile, Jr. (Jason Carbone) is given a Model 36 by his uncle Ralph (Joe Pantoliano), who tells him the .38 isn't very intimidating but is very reliable and will "always get the job done". A Model 36 is also visible in Pussy's hidden armory. Corrado "Uncle Junior" Soprano (Dominic Chianese) shoots Tony Soprano in the stomach with a Model 36 during a case of mistaken identity in Members Only (6.01). (IMFDB thanks The Golden Closet for providing the documentation on this gun, as well as the image seen below.)
While beating up the husband-wife brothel owners in Big Girls Don't Cry (2.05), Furio Giunta (Federico Castelluccio) takes a Smith & Wesson Model 586 from behind the brothel's counter and fires several shots into the air to scare off patrons before ditching it.

Phil Leotardo (Frank Vincent) holds a Snubnose [[Smith & Wesson Model 686 on Lorraine Calluzzo (Patti D'Arbanville) in Where's Johnny (5.03), firing it at her chest through a phone book (but only getting to the 'R' section). Tony Soprano (James Gandolfini) holds one on Christopher in Irregular Around the Margins (5.05) when Christopher holds his own gun on him and accuses him of sleeping with his girlfriend.
Unidentified Revolver
Patsy Parisi (Dan Grimaldi) shows up drunk at Tony's house in "Mr. Ruggiero's Neighborhood" (3.01) with a revolver, possibly a Ruger.

Rifles / Carbines
AK-47
In Pilot (1.01), Carmela (Edie Falco) confronts a presumed burglar outside her house at night with an AK-47. Several AKs and variants are discovered by FBI agents under Pussy's pool table during the bar raid in Nobody Knows Anything (1.11).
Armalite AR-10
Bobby Bacala (Steven R. Schirripa) gives Tony Soprano (James Gandolfini) an Armalite AR-10 for his 47th birthday in Soprano Home Movies (6.13). Bobby describes the weapon as "800 rounds per... Panther-fluted barrel." It appears to be a DPMS rifle not an Armalite which might give some meaning to the panther line. Tony keeps this weapon when he goes into hiding in The Blue Comet (6.20) and Made in America (6.21). Although Bobby specifically refers to the weapon as an AR-10, he is certainly not a qualified weapons expert.
Closeups of the gun in episode "Soprano Home Movies(6.13)" show that the gun used in show was actually an AR15 with a magazine modified to look like the AR10.
Oddly, in both episodes "The Blue Comet (6.20)" and "Made in America (6.21)", it's very clear that it is indeed an AR-10. A sure sign of this is the magwell is enlarged and widened. Also, Tony has removed the Aimpoint Optic and Crimson Trace vertical grip.
In A Hit is a Hit (1.10), Christopher's rapper friend Massive Genius (Bokeem Woodbine) has a nickel-plated Norinco Type 56-1 with ivory furniture (including a Romanian AIM-style vertical grip). This weapon was originally made for the movie Belly, and it was also seen in Lord of War.
A Springfield Model 1842 musket hangs from the bar where Meadow Soprano (Jamie-Lynn Sigler) gets drunk with the girls she meets at Colby College in Maine in "College" (1.05).
Springfield M1903
In "House Arrest" (2.11), Paulie (Tony Sirico) finds an M1903 Springfield among a collection of World War II swag and plays around, racking the bolt on it.
Sporter Mauser 98
Artie Bucco (John Ventimiglia) holds a sporterized Mauser up to Tony after he finds out Tony burnt down his restaurant in the first season episode I Dream of Jeannie Cusamano (1.13) before breaking it apart against his station wagon out of shame and anger. Bobby Bacala (Steven R. Schirripa) carries a similar rifle when helping Tony look for Paulie and Christopher in Pine Barrens (3.11).
Shotguns
Beretta DT-10

Remington 870 Folding Stock
In The Legend Of Tennessee Moltisanti (1.08), Tony (James Gandolfini) is seen taking a Remington 870 Police Magnum equipped with a top-folding stock from a cash/gun stash in a ceiling air duct opening in his house and putting it in a duffel bag as part of his 'spring cleaning' in anticipation of a police raid. He later stashes it under some clothes in a box in the closet of his mother's retirement home apartment.
Winchester Model 1300
Two shotguns, including a pistol-gripped Winchester Model 1300, are seen inside Pussy's hidden wall armory in From Where to Eternity (2.09).
Sawed-Off Side-by-Side Double-Barreled Shotgun

Benny Fazio (Max Casella) spots a Mk 2 hand grenade inside a secret compartment in the Soprano home where Tony and Carmela keep an Type 84S and a M1911A1.
Bobby Bacala (Steven R. Schirripa) uses a Beretta non-gun in Soprano Home Movies (6.13) to carry out a hit for Tony's French-Canadian friends. In the same episode, a flashback to Johnny Sack's arrest in 2004 shows Tony (James Gandolfini) throwing a pistol into the snow, which a neighbor kid retrieves later that night. Strangely, the pistol resembles a Glock-type weapon when it is thrown by Tony, but is a Beretta non-gun when it is recovered.
Ally Boy Barese uses a Colt .45 non-gun in Amour Fou (3.12) to execute Dino Zerilli after the card game robbery attempt. In the same episode, Patsy Parisi (Dan Grimaldi) holds a 1911 non-gun to Gloria Trillo (Annabella Sciorra) when she refuses to stay away from Tony.
