One of the commando carries a Walther P99 which we most notably seen when the commandos storm the mansion in the beginning of the movie.
Springfield Armoury Mil-Spec M1911A1
Rain Ocampo (Michelle Rodriguez) uses a Springfield Armoury Mil-Spec M1911A1 with Pachmayer grips and an accessory rail as her sidearm. This weapon is also shared between the characters, specifically Alice (Milla Jovovich), when all of their other weapons run out of ammunition. Matt (Eric Mabius) can also be seen trying to draw a Springfield Armory M1911A1 on the commandos in the beginning of the movie before it is taken away from him.
I would stick my cock so far in her ass it isn't even funny.
Dude. Very inappropriate. If you want to talk like that there are other sites for that.
Taurus Model 431
Chad Kaplan (Martin Crewes) uses a stainless Taurus Model 431 five shot .44 special revolver as his weapon.
Smith & Wesson 5906
J.D. Salinas (Pasquale Aleardi) uses a Smith & Wesson 5906 as his sidearm. He also uses this weapon to shoot a zombie two times in the knee caps and three shots to the chest before Rain unloads her MP5K and sends it flying unrealisticly.
In the movie, you can see One also shouldering his G36 by the AG36's pistol grip. It is a very incorrect way to hold this kind of weapon. Unless someone can point out how tactically sound it is.
Alice (Milla Jovovich) grabs a Hi-Standard K-120 - 20" barreled 12 gauge riot/self defense shotgun with rifle sights out of a police car in the abandoned streets at the end of the film.
