Det. Sgt. James "Sonny" Crockett (Don Johnson) uses a SIG-Sauer P220 in the pilot episode of the show. Considering that the pilot episode was filmed in the spring of 1984 the model used would most likely have been the European model with the heel-clip magazine release.
Detonics Pocket 9
Used as a back up pistol to Sonny Crockett's SIG-Sauer P220 in the pilot, in which Crockett carries the Detonics Pocket 9 in his rear waistband near the small of his back.
Dornaus & Dixon Bren Ten
Sonny Crockett (Don Johnson) uses a Bren Ten in the first season of the show. It was essentially a beefed-up CZ 75 chambered for the original 10mm Norma Auto cartridge which differs slightly in case length from later 10mm rounds. This round was HOT, and consequently damaged the guns. In the '80s this was a new cartridge, but is rarely used in modern day. The company of Dornaus& Dixon was an ill-fated one, and since the producers of the Miami Vice-series would not use discontinued guns, it was replaced with the S&W 645 auto pistol
"The two guns were ordered specifically for the show by Michael Mann's production company. They did not come off the assembly line, but were built by Tom Dornaus personally. Tom did the initial blank conversion, if you want to call it that, but actually these two guns were built from the ground up specifically for firing blanks. He used major components which were not deemed suitable for production guns, but were perfectly adequate for a blank gun. The two guns were Standard Models with the old style rear sight assembly and no trigger stop screw. All external markings were standard Bren Ten. The only difference being that the guns had recoil springs and barrels designed to fire .45 ACP blanks. The barrel does not carry any caliber designation roll mark however. Because the ejection port on a Bren Ten is so large I don't believe that it had to be enlarged to accommodate the elongated .45 ACP blank cases. (Remember that the blank cases are in the shape of a loaded round WITH bullet seated.) Michael Mann requested specifically that the slides be a light color (hard chrome) for enhanced visibility. The hard chrome work was done by a small firm in the Huntington Beach area at that time. Both guns carry a special serial number. One of the guns is in the possession of a major collector in Pennsylvania and the other is owned by one of the show's producers, I believe. They weren't Marksmans or Standard Models with conversion kits. They were two specially built guns". from http://www.bren-ten.com/website/id5.html
Detonics Combatmaster
Sonny Crockett (Don Johnson) carries a Detonics Combatmaster as a backup gun, in an ankle holster. In reality the Detonics would have been a substantial handgun to carry in an ankle holster. One of the court officer's uses a Combatmaster during Leon's arrainment in the pilot episode. A drug dealer in "Milk Run" also uses a Combatmaster.
A J-frame Smith & Wesson Model 36 "Chief's Special is seen on the bed in Tubbs' hotel room in the pilot episode. Det. Gina Calabrese (Saundra Santiago) also uses this as her sidearm throughout the season, as well as Det. Trudy Joplin (Olivia Brown).

Another court officer in the pilot episode points a nickel S&W 29 at Leon. In "Calderone's Demise", when they are getting ready to face Calderone, Tubbs asks Crockett for a nickel S&W 29, to which Crockett responds "We're not going after an elephant Tubbs" before handing it to him. Lt. Castillo (Edward James Olmos) carries a nickel S&W 29 during the opening scene in "No Exit". Billie Joe Higgins (Jay Patterson) holds a nickel S&W 29 on Crockett and Tubbs in "Glades".

Franchi SPAS-12
Two of Calderone's henchmen are seen holding Franchi SPAS-12s during the climax of the pilot episode before they are held at gunpoint by Crockett and Tubbs. A nickel plated SPAS-12 is used by a hired killer Ludovici Armstrong (Jim Zubiena) in the episode "The Hit List". Jaime Escobar also uses a nickel plated SPAS-12 in "The Maze". It is likely that the same nickel plated shotgun is used in both episodes.
Mossberg 500
Many Metro-Dade police officers, Vice detectives, and SRT members use Mossberg 500s in "Cool Runnin", "The Hit List", "The Maze" and "Evan", always with wooden furniture.

Blunderbuss Flintlock
Used by Clem (Al Cox) in "Glades", referred to as a "Gator-Getter". After it misfires several times, he finally kills a Colombian who was about to kill Crockett. The muzzle has the conical shape so you could jam rocks, nails, and other junk in the barrel. It was a primative shotgun. (Thanks to Gunmaster45 for identifying this one)
Elio uses a High Standard Model 10 in "The Maze". One of the assassins also uses one in "Lombard".
Sub-Machine Guns
Interdynamic KG-99

M16
Bramlette (Keith Szarabajka) and one of his men use original, bolt assist-less M16s with M16A1 flash Hiders in "Glades". The M16s switch with the M16A1s because of Continuity errors. Several characters, including SRT members in "The Maze", also use M16s.
