CSI: Miami

Horatio Caine uses a Beretta Cougar in the first seasons, but later switches to a Sig Sauer P220 compact pistol. He also owns a Beretta 92, as seen in episode "Cyber-lebrity" and is given a Browning Hi-Power in .40 SW, as seen in "Ambush" and "All In". In one episode (Going, Going, Gone) he uses a HK G3-varient police-issue sniper rifle.

Calliegh uses a SW Ladysmith and a Kimber Pro carry alternatingly throughout the series

Eric Delko uses a Heckler & Koch USP as his 9mm weapon of choice

Ryan Wolfe uses a Beretta 92 Elite as his compulsivly cleaned duty weapon

Frank Tripp packs a Sig Sauer P229

Natalia Boa Vista finally aquires a glock 19 9mm in season six as her carry weapon

Interesting note- In the season 6 final, Kyle, Caine's son, is seen checking and loading a Smith and Wesson pistol, in what appears to be .40 sw.

• Please confirm model and erase this note*

Glock, Smith & Wesson, Colt, Beretta, and especially Sigarms weapons are very common in the hands of minor and side characters and villains throughout the series.

By far throughout the show the most seen gun, used by CSIs, criminals, and other characters is the M1911 pistol series.
