Hawaii Five-O is the 2010 television update of the classic CBS television series. In this version of the series, Steve McGarrett (Alex O'Loughlin) is a former Navy SEAL recruited by the governor of Hawaii to head up a new crime task force in the state known as Five-O. The rest of the cast includes Scott Caan as Danny "Danno" Williams, Daniel Dae Kim as Chin Ho Kelly, and Grace Park as Kono Kalakaua.
The following weapons were used in the series Hawaii Five-O:
Cmdr. Steve McGarrett (Alex O'Loughlin) carries a SIG-Sauer P226 as his sidearm (most likely due to his background as a Navy SEAL, which issues the P226) for the first four episodes of the show. In "Haʻiʻole", a terrorist suspect named Kurt Hauff has a two-tone Sig Sauer P226.
SIG-Sauer P226 E2
In "Nalowale" (S01E15), McGarrett switches over to the new SIG-Sauer P226 E2. Beginning in "Palekaiko" he carries it with a SIG-Sauer STL-900L Tactical Light/Laser mounted on the frame. The laser can be seen at the beginning of "Ke Kinohi".
Heckler & Koch P30
In "Ke Kinohi" (S01E13), Danny 'Danno' Williams switches his sidearm from his SIG Pro to a Heckler & Koch P30. Also, as a result of a continuity error, the Heckler & Koch USP Compact used by Drago Zankovic (Peter Stormare) in "Ohana" (Ep.1.2) becomes a newer Heckler & Koch P30 in a single close-up. It later goes back to a USP Compact when he's holding the gun in Kono's car.
SIG Pro SP2009
The SIG Pro SP2009 is the main sidearm carried by Detective Danny "Danno" Williams (Scott Caan) up until he switches to a Heckler & Koch P30 in 'Ke Kinohi'. Another is seen in the hands of a Yakuza gangster.

A Heckler & Koch USP Compact is used by Drago Zankovic (Peter Stormare) in Episode 1.2, "Ohana". Due to a continuity error, the weapon becomes a Heckler & Koch P30 when he's shown holding it to head of Evan Lowry (Colin Ford) in a close-up.

Steve uses this as his sidearm in "Haʻiʻole" due to his initial arrest as a suspect in murdering the governor in the end of Season 1 when HPD had possibly confiscated all of Five-0's weapons and equipment, forcing Steve to make do with whatever pistol he can get his hands on.
