Smallville was an American television sci-fi drama that was a different take on the "Superman" character. The series followed a young Clark Kent (Tom Welling) slowly discovering his superpowers in his rural American town. Unlike other versions of the character, Clark never actually becomes Superman (until the final season of the series). The series aired for 10 seasons from 2001 to 2011 on the WB network, which eventually become the CW.
The following weapons were used in the television series Smallville - Season 1:
The Beretta 92FS Inox is seen in use by Lex Luthor (Michael Rosenbaum), also seen switched hands and used by Lana Lang (Kristin Kreuk) once to shoot open Lex's suitcase. Security, cops, and guards also seen in use. In season 7, Lex was seen duel wielding these. In fact, this is the most commonly seen weapon in the entire series, usually in the hands of Lex. In season 4 we see a suppressed one, also taken by Lex from his would be assassin.
Gabriel Duncan (Johnny Lewis) uses a Beretta 92FS to kill the guards in the missile silo, and to shoot and kill Clark Kent (Tom Welling). Gabriel was later shot with it by Chloe Sullivan (Allison Mack). It appears to be a non-gun, as it doesn't cycle when it fires.
Sam Phelan uses his Glock 17 to shoot at Clark in "Rogue" (S1E09). In "Red" (S2E04), Ted Palmer (Michael Tomlinson) carries a Glock 17 during the episode. The Glock 17 is used by police officers and other characters in the series. Also the Glock featured is a second generation Glock, giveaways being the finger grooves and tactical rail are absent.
A Smith & Wesson Model 610 is a prop gun used in the episode as a prop gun for a movie made. It was decorated as a villain weapon. Season 7, episode 5 "Action". This is most likely the same revolver that we saw Blade used briefly in Blade Trinity.
What appears to be a Heckler & Koch G36C with a modified scope and laser sight is used in the season three episode "Extinction" by the character Van McNulty (Jesse Metcalf).
