White She-Devil (Denise Richards) carries a pair of Beretta 92FS Inox pistols in hip holsters after she reveals her true identity to Undercover Brother.
The security guards at the golf course, as well Mr. Feather's right hand man, Mr. Elias, are armed with Glock 17s. Conspiracy Brother (Dave Chappelle) later takes the pistol away from Mr. Elias (Jake Noseworthy), forcing him to dance at gunpoint. Smart Brother (Gregory Anthony Williams) later pulls one when the intruder alarm at the B.R.O.T.H.E.R.H.O.O.D. headquarters goes off.
One of White She-Devil's enforcers (Darren McGuire) uses a nickel-plated Desert Eagle. Although, as the screenshot indicates, it's actually an Airsoft pistol.
Desert Eagle MK VII - .44 Magnum w/ nickel finish.Error creating thumbnail: File missingA really convenient angle for revealing to the audience that the Desert Eagle is actually an Airsoft.
Heckler & Koch Mark 23
White She-Devil's other enforcer (Tig Fong) carries a Heckler & Koch Mark 23. Since he never fires it, it's possible that like his fellow enforcer's pistol, this is also an Airsoft.
Conspiracy Brother (Dave Chappelle) carries a Ruger KP89 which he pulled out when the intruder alarm goes off at the B.R.O.T.H.E.R.H.O.O.D. headquarters.
The Man's security guards carry faux Heckler and Hoch MP5 submachine guns, which are actually cut down HK94 carbines. They are never actually fired in the movie.
