I don't really think the square gun drawing is accurate at all. I paused the trailer last week and it looks like a Glock. Well, a vac-form of a Glock with a lot of stuff added to it, especially in front of the trigger of course. The detail is really soft, but the profile is definitely Glock. Also looks like the ejection port was extended quite a bit. Not sure how a gun is supposed to feed ammo that drops into the bottom of the mag well; how's the mag spring and follower supposed to feed it to the chamber? Oh well, set Suspension Of Disbelief Generator to maximum. At least the flick looks like good mindless entertainment, and Milla ain't bad on the eyes either.
