Erik Heller (Eric Bana) carries a two-tone Beretta 92FS as his sidearm, notably when he assaults Marissa Wiegler's hotel room. Several CIA operatives and one of Isaacs' (Tom Hollander) men carry standard Berettas. However, their Berettas are never seen well enough to actually screencap.
Glock 17
A CIA officer named Lewis in the Camp G control room draws a Glock 17 during Hanna's escape
Luger P08
Hanna uses a Luger P08 as a secondary hunting weapon and also as a training weapon.
Vektor SP1
Hanna (Saoirse Ronan) takes a Vektor SP1 off a guard and uses it while escaping the CIA's custody.
Walther PP
Marissa Wiegler (Cate Blanchett) is seen using a nickel Walther PP with wood grips, sometimes fitted with a suppressor. Hanna Heller (Saoirse Ronan) uses it at the end of the film.
Assault Rifles
M4A1 Carbine
The CIA Special Operations Group team that raids Hanna's cabin are armed with M4A1 carbines fitted with M68 Aimpoint Scopes, folding front sights, and Surefire flashlights. The shape of the front sight, which matches a front sight block marketed by Precision Reflex Inc., distinguishes them from the HK416 that they were previously IDed as. May possibly be airsoft replicas as they are never fired on screen.
M4A1 with M203 Grenade Launcher
One of the CIA SOG teams that assaults the cabin is armed with an M4A1 fitted with an M203 grenade launcher. Another such combination is seen in stock footage on television.
