Sleepless Night (French title: Nuit Blanche) is a 2011 French crime thriller directed by Frédéric Jardin. Vincent (Tomer Sisley) is a cop with a connection to the criminal underground. One day he finds himself exposed when he and his partner Manuel (Laurent Stocker) are caught stealing cocaine from José Marciano (Serge Riaboukine), a powerful drug dealer. His son kidnapped, Vincent has one night to make it right. The film was subsequently remade as the 2017 US crime thriller Sleepless that stars Jamie Foxx.
The following weapons were used in the film Sleepless Night (Nuit blanche):
Vincent (Tomer Sisley) carries a SIG-Sauer P226R. He hides it just after entering the nightclub but doesn't get a chance to retrieve it. He later takes Feydek's, who also uses a SIG P226R. It is rather an uncommon weapon for a Turkish drug dealer: he could have taken it from a Police officer, or bought it from a crooked cop.
Glock 26
Vignali (Lizzie Brocheré) carries a Glock 26 as her personal side arm until Vincent disarms her and disposes of the gun. Manuel (Laurent Stocker) also gives Vincent a Glock 26 when they meet a few moments later (the same weapon is probably used twice on the set).
Jericho 941
José Marciano (Serge Riaboukine) uses a Jericho 941 as his main weapon. Judging by the overall aspect of the gun and the shape/length of the slide release, it seems to be an earlier model.
Browning Hi-Power "Type 73"
Marciano seems to be using a Browning Hi-Power "Type 73" as his secondary weapon. We don't actually see the gun until Vincent confronts him and then walks away with both the Jericho and the Browning. Vincent uses it as a backup weapon too.
CZ 75 "Pre-B"
Yilmaz (Birol Ünel) seems to be using a CZ 75 "Pre-B" pistol. It is hard to tell though, since he never draws it in the light. However, the gun does not feature a wheel-shaped hammer like the later models. Also, its rounded trigger-guard doesn't match the shape of later versions (no index finger grasp). Finally, the shape of the barrel seems closer to the earlier model's.
CZ 75B Stainless
One of Feydek's thugs (Vincent Bersoulle) uses a stainless CZ 75B. Vignali later gets hold of the gun.
Lacombe (Julien Boisselier) carries a SIG P210. He fires it several times, but it's only during the final scene that we can take a good look at it.
Judging from the inscriptions on the frame and the sight, it seems to be an earlier version (probably a P210-5 or P210-6 built under the name "SIG" in Switzerland) and not the recent "SIG-Sauer" P210 Legend crafted in Germany. It's a gun frequently seen in shooting competitions.
Furthermore, its overall length (8.5 inches) and its price (it retails between $2500 and $3000 when legally purchased in France) hardly makes it an everyday carry weapon.
