Det. Sgt. James "Sonny" Crockett (Don Johnson) uses a SIG-Sauer P220 in "Brother's Keeper" (S1E01), 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
Crockett carries the Detonics Pocket 9 in his rear waistband near the small of his back as a back up pistol to his SIG-Sauer P220 in the pilot episode "Brother's Keeper" (S1E01).
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 Smith & Wesson 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

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.
