No his left hand is more holding it like a Thompson WW II gun without a handle grip
The screenshot with the "RCW" on the table, you will notice the HUD is green and not the yellowish orange that is Fallout New Vegas. That screenshot is from Fallout 3 . . .
Ohhh I see what you mean, you mean like a vertical foregrip.
And I anticipated your second point.
Let me dispel some misconceptions.
First off, the second pic doesn't show a vertical foregrip either, the crosshair is just situated where one would be, giving the illusion that one exists.
Second, I assure you the second screenshot is from New Vegas. The HUD is blue, not green.
It is very silly to think that New Vegas would force you to use the default amber color for your HUD and Pip Boy, and wouldn't let you customize it.
After all, Fallout 3 let you change the colors, so why not in New Vegas?
The color has just been customized according to player preference. I ask you, why would there be a "Laser RCW" in Fallout 3 when that weapon didn't exist until new vegas?
