A character on Little Caesar, the fictional TV show in the film meant to resemble The Sopranos, carries out a mob hit with an Ithaca 37. Jelly (Joe Viterelli) also has one in his armory that he offers to Dr. Sobel before the armored car heist.
Two mobsters on Little Caesar use LaFrance Specialties M16Ks to carry out a mob hit. That's no M16K. Looks like an M4 or something. It's go the front sight/gas block and a longer barrel than the M16K.--Mandolin 22:13, 25 September 2010 (UTC)
A prison guard hired to assassinate Paul Vitti uses a suppressed Taurus PT92. Anthony Bella (Anthony LaPaglia) has a PT92 as "Nicky Caesar" on the set of Little Caesar, seen locked open when he is arguing with the armored car officers in the climax.
That looks more like a HK MP-5K-PDW without the side folding stock. if you look close you can clearly see the three-lug muzzle that can accept quick-detachable MP-5 silencers, which the MP5-K doesnt have.
Beretta Cheetah
Lou Rigazzi (Frank Gio) uses a suppressed Beretta Cheetah when his men bring the failed gunman into his office. Paul Vitti (Robert De Niro) also carries an unsuppressed Cheetah, drawing it from a hiding place in his trailer on the set of Little Caesar.
Paul Vitti (Robert De Niro) keeps a third-generation Glock 17 under his couch cushions in his trailer, which he tosses into a bag when hiding out from the police and Rigazzi's men. "Al Pacino" (William DeMeo) carries one during the planning and execution of the heist. The armored car officers also carry them in holsters.
Jelly (Joe Viterelli) carries a nickel Smith & Wesson Model 36, which he draws when a Little Caesar crew member enters Vitti's trailer. One of the Little Caesar cast members also uses one during filming.
Jelly has an M16A2 in his collection, asking Dr. Sobel if he can handle an M16. When Sobel asks if he means to shoot it, Jelly sarcastically tells him he wants him to twirl it around his finger.
Jelly asks Dr. Sobel if he wants an "AK" or a "Kalashnikov", referring to both the Norinco Type 56 and AKS-74U he has on the table.

Franchi SPAS-12
Jelly keeps a Franchi SPAS-12 with a solid fixed stock/pistol grip combination in his collection.
Dr. Ben Sobel (Billy Crystal) asks Jelly if he can use a nickel snubnose Colt Python instead of one of the larger assault rifles. Jelly holds the gun laughing, remembering a lot of "good times" from the revolver, then hands it to him. Eddie DeVol (Raymond Franza) also carries a blued snubnose model.
One of Vitti's men carries a Heckler & Koch MP5SD during the armored car heist.
Edit: This is an airsoft gun made by UHC. Note the finger groves on the handguard, which no production MP5SD's have.
