Sonny Crockett
Originally, James "Sonny" Crockett was to use a SIG-Sauer P220 in .45 Auto which is evident in the pilot episode. He also carries a Detonics Pocket 9 as a backup, tucked in his rear waistband near the small of his back. But it was later decided that a more state-of-the-art gun was to be used by Don Johnson. During the first season, he used a Bren Ten pistol carried in a Ted Blocker "Lifeline" shoulder holster rig. Due to Don Johnson's dissatisfaction with the "Lifeline" rig, the Jackass Leather Company (later renamed Galco International) "Original Jackass Rig" shoulder holster rig was personally fitted for him by Rick Gallagher (President of Galco). Finally the Galco "Miami Classic" shoulder holster was designed and used. The Bren Ten, manufactured by Dornaus & Dixon, was a stainless steel handgun notable as the first ever chambered in the powerful 10 mm Auto caliber. The Bren Ten was originally manufactured as a two-tone weapon: the carbon steel slide was black oxide and frame was stainless steel. The model used in Miami Vice had a hard chromed matte finished slide so that it showed up better during night shots. The pistol used in the show was chambered in .45 ACP, as opposed to the standard 10mm Auto. After the Dornaus & Dixon company went out of business in 1986, the product placement contract went to Smith & Wesson. Starting with the third season, Sonny used a 2nd Generation series Smith & Wesson Model 645. This was a full-sized 5-inch-barreled stainless steel service pistol in .45ACP. Galco Gunleather, formerly Jackass Leather Co., built a "Miami Classic" shoulder holster for the S&W 645 used. In the Galco Gunleather headquarters, there is a large display that contains the Miami Vice shoulder holster rig that Don Johnson wore, accompanied by an autographed photo of him. In late 1988 Smith & Wesson unveiled their new 3rd Generation Series of auto pistols, so for the last season Sonny's Model 645 was replaced with the new Smith & Wesson Model 4506. This pistol had 20+ design improvements including a one piece arched grip. Sonny's M 4506 can be seen in the beginning of the episode "Victim of Circumstance" when he is sitting in a cafe and looking at it. Sonny also carried a .45 ACP Detonics Combat-Master backup gun in an ankle holster on his left leg, replacing the Pocket 9 from the pilot episode. It can be seen in the bar scene shootout in the "Prodigal Son" episodes. In the last series episode "Freefall" Crockett is placing what looks to be a S&W CS45 (compact alloy framed .45ACP) in his ankle holster.
