In the pilot episode, this gun is in drug dealer, Krazy 8's possession. Not long after, Walt becomes its new owner before Jesse disposes of it in the following episode.
Tuco uses a Jericho 941 with a two-tone finish as his sidearm. Jesse takes it from him while they are fighting on the ground and uses it to wound him. It is later buried in the desert.
Hank Schrader shows off his issue Glock 22 during the party in the first episode. He actually refers to it as a Glock 22 and praises the power of the .40-caliber round over 9x19mm (claiming to have seen the latter cartridge ricochet off a car windshield). He uses the Glock 22 in his shootout with Tuco in the episode "Grilled" of season two. It can be seen occasionally throughout season two and three.
This is the revolver purchased by Jesse. He uses it to intimidate an unnamed female junkie and her husband, Spooge after they rip-off one of Jesse's dealers.
Walter White purchases a Ruger LCR from an illegal arms dealer (Played by Jim Beaver) along with a leather I.W.B. holster in S4E2 "Thirty-Eight Snub". The arms dealer recommends he load it with 158 grain hollow points for good stopping power, and also recommends he not cross draw unless he is sitting down.
Jesse buys and plans to use a Beretta Cheetah to take revenge on drug dealers who killed his friend, but he never fires it as Walt intervenes with his car.
Jesse & Mike pick up Taurus PT92AFS pistols from dead men and use them when escaping Don Eladio's compound, Jesse empties his into a cartel memeber who wounds Mike.
Heckler & Koch Mark 23
This pistol is used with a suppressor by Mike in the season 3 finale.
The M4 Carbine is carried by Tuco when he takes Walt and Jesse hostage. Walt later takes this weapon from him when Tuco is bashed over the head with a rock by Jesse. However, Tuco gets it out of the car when DEA agent Hank, who is also Walt's brother-in-law, arrives at Tuco's hideout. DEA agents also use M4A1s when they arrest Jesse in 'Bit By a Dead Bee' It is also seen in the music video for "Negro y Azul". Two are in the video, one lying on the ground and another propped up against a pickup truck with a telescopic sight and underslung grenade/flare launcher mounted.
Clovis, a tow truck and junkyard owner who is a cousin of an associate of Jesse's, uses a shortened Mossberg 500 to threaten an intruder sleeping in Jesse's RV, but put up his gun when the intruder turns out to be Jesse himself (S2E4, "Down"). Specifically, the weapon appears to be a cut down 500AT; the stock has either been shortened to, or replaced with, a pistol grip, but the barrel appears to be original as it has the original bead sight (thereby narrowly escaping being a "short-barreled shotgun" for purposes of the 1934 National Firearms Act).
A music video appears in the Season 2 episode "Negro Y Azul" (Spainish for black and blue). A multitude of weapons appear in the video.
Unknown Revolver
An unknown Smith & Wesson model revolver can be seen in the "Negro Y Azul" music video. It is sitting next to several bags of the Walt's signature blue meth.
