Unknown compact pistol
The murder weapon in "We Like Mike" (S07E20) is an unknown automatic pistol. It appears to be some sort of Saturday Night Special. No one mentions any other details. --Funkychinaman 16:21, 17 July 2012 (CDT)
Unknown pistol
The murder weapon in "Progeny" (S05E12) is an unknown pistol. It sort of resembles a Heckler & Koch P9S, but this pistol looks like it has a hammer. --Funkychinaman 20:40, 25 July 2012 (CDT)
It seems a little large for a Bersa Thunder. This appears to be a full-sized handgun. Plus, the hammer is different. --Funkychinaman 20:47, 6 August 2012 (CDT)

Unknown Derringer
Cerreta finds an unknown derringer in the victim's apartment. Cerreta is later seen handling it at the ballistics lab.
The Glock 19 is the main sidearm carried by the majority of NYPD detectives on the show. The first regular detective seen carrying the Glock was Det. Rey Curtis (Benjamin Bratt). The other detectives seen carrying the Glock include Detectives Ed Green (Jesse L. Martin), Nick Falco (Michael Imperioli), Nina Cassidy (Milena Govich), Cyrus Lupo (Jeremy Sisto) and Kevin Bernard (Anthony Anderson). NYPD Officers are seen carrying Glocks as well. The Glock Model 19 is one of the three semi-automatic 9mm pistols authorized by the NYPD for their officers to carry.
Smith & Wesson Model 36
Detective Lennie Briscoe (Jerry Orbach) can be seen carrying a Smith and Wesson Model 36 during his time on the show. Det. Mike Logan (Chris Noth), Sgt. Max Greevey (George Dzundza), Sgt. Phil Cerreta (Paul Sorvino), as well as Lt. Anita Van Buren (S. Epatha Merkerson) and Captain Donald Cragen (Dann Florek) are seen carrying Model 36s as well. Van Buren notably using hers in Season 5's "Competence" (S05E18). The Model 36 is used by many veteran NYPD Detectives.
Smith & Wesson Model 19 Snub
Detective Joe Fontana (Dennis Farina) carries a Smith & Wesson Model 19 with a 2.5-inch barrel. It could be assumed that his revolver is loaded with .38 special rounds since .357 Magnum revolvers are not on the approved carry list.
Beretta 92F/FS
A Beretta 92FS is found in Season 3's "Securitate" (S3E20) and is identified as a "Beretta nine millimeter" by Detective Logan. In a continuity break, a M1911A1 on the counter turns into a Beretta 92F in "Poison Ivy" (S01E08). (It's likely a 92F rather than a 92FS because the episode was filmed in 1990.)
M1911A1
In the episode "Animal Instinct", Dirk Chesney (David Schechter) carries an M1911A1 pistol, which is taken by Det. Logan and Det. Briscoe when they arrest him. Another appears in the episode "Mother Love". Sgt. Greevey pulls a M1911A1 out of a gunsmith's (John Capodice) drawer in "Poison Ivy" (S01E08). A patron at a shooting range is seen with a 9mm M1911A1 in "Trust" (S02E15).
Ruger Redhawk
A .357 Magnum Ruger Redhawk is a piece of evidence in "Poison Ivy" (S01E08). While it is never called that by name, characters refer to it as a Magnum and say that it was chambered in .357 Magnum. A patron at a shooting range is seen with a Redhawk in "Trust" (S02E15).
Smith & Wesson Model 10
Smith & Wesson Model 10s are carried by the NYPD Officers in the initial seasons of the series. The Smith and Wesson Model 10 was an authorized weapon for all NYPD officers who had entered onto the job on or prior to 1986.
Astra 200
What appears to be a Astra 200 is used to kill a police officer in "A Death in the Family" (S01E13). It is picked up off the street by Revina (Karina Arroyave) who draws it on Dets. Greevey and Logan. It is described as a "Smith & Wesson .32."
Charter Arms Undercover
A Charter Arms Undercover is found in a victim's apartment in "Mushrooms" (S01E17). Another one appears in Season 5's "Wannabe" (S05E16). The gun is said to be chambered in .32 H&R Magnum, which is incorrect, since the Undercover is only chambered in .38 Special, and would therefore be the Undercoverette model, which would be chambered in .32 H&R Magnum.
Smith & Wesson 639
A Smith & Wesson 639 is seen in a stash of guns found in a crackhouse in "Mushrooms" (S01E17).
Browning Hi-Power
A Browning Hi-Power is found in the possession of a suspect in "Severance" (S02E13).
Ruger Speed Six
The murder weapon in "Trust" (S02E15) is a Ruger Speed Six. It is described, however, by the ballistics expert as a Ruger Security Six, with "custom Pachmayr grip, modified hammer and trigger." Since the owner is described as a target shooter, a Security Six, which has adjustable sights, would make more sense than a Speed Six, which only has fixed sights.
H&R Model 777 Super Sportsman
Forensics Tech Arlene Shrier (Christine Farrell) demonstrates the difference between single action and double action for the detectives (and the audience) with a H&R Model 777 Super Sportsman in "Trust" (S02E15). It's a top-break, single action revolver, with target sights.
A nickel-plated or stainless Tanfoglio Titan II is the murder weapon in "Intolerance" (S02E20). It is described by ballistics as a "Tanfoglio Titan .380."
Colt Detective Special
Two third gen Colt Detective Specials are seen in a "lineup" of revolvers in "Working Stiff" (S02E22). The murder weapon in "White Rabbit" (S05E05) is a first generation Colt Detective Special. The murder weapon in "Causa Mortis" (S07E01) was one as well, but victim was not shot, but bludgeoned with the butt of the gun.
Smith & Wesson 61 Escort
In the episode "Mother Love" (S03E15), Det. Logan finds a Smith & Wesson 61 Escort in the apartment of Jonas "Skate" Stark (Leland Gantt), identifying it as a ".22". Another appears in the episode "Purple Heart" (S05E23).
Smith & Wesson Model 64
Smith & Wesson Model 64's are seen in various episodes. The S&W Model 64 was modified to meet NYPD requirements and designated as the Model NY-1 by the NYPD and was the authorized issued revolver for all officers of the NYPD who entered on to "the Job" after 1986 until the department stopped issuing revolvers and began issuing semi-automatic 9mm pistols starting around 1992.
Beretta M1934
Arms dealer George Lobrano (Mark Margolis) draws and fires a Beretta M1934 in "Prince of Darkness" (S03E08). A Beretta M1934 was also seen used in "Blood Money" (S10E08).

Raven Arms MP-25
A Raven Arms MP-25 is seen in Season 5's "Competence" (S5E18) and is identified as such a weapon in the episode.
Beretta Model 70
What appears to be a Beretta Model 70 is seen in the episode "Pride" (S05E23). While it's said to be a .22, the gun's front sights are not seen clearly enough to distinguish it from the Model 71, which is a .22.
Budischowsky TP-70
The murder weapon in "I.D." (S07E02) is a .25 caliber Budischowsky TP-70. It is described by both EADA Jack McCoy (Sam Waterston) and Det. Rey Curtis as a ".25 caliber Fluger pistol," although the close captions say "Ruger" instead of "Fluger."
Smith & Wesson 5946
Lennie Briscoe is shown with a Smith & Wesson 5946 at a police range in "Corruption" (S07E05). He drew his usual Smith & Wesson Model 36 earlier in the episode.

It's described as "the Smith & Wesson."
