Machete

What originally started as a gag trailer in Grindhouse (Planet Terror, Death Proof) has turned into Robert Rodriguez' next film.

These are the guns seen in the newest trailer

Machete (2010)

Walther P99

One (possibly two) heavily customised P99s can be seen on a table of guns in the trailer

(red circle) The pistol on the left is a P99, but the one on the right I am not so sure about

A Tec-9 can be seen on the same table of guns

Unknown Assault Rifle

Used by Michele Rodriguez' character during the trailer. It is too obscured by prop parts to make a decent guess. It could also be a prop gun too

Either a prop gun or an insanely dressed up assault rifle

Unknown Sniper Rifle

Used by the man who shoots Machete and sets him off on his quest of vengeance

Notice how both the rifle and the actor holding it have changed from the original (the one in Grindhouse) trailer
