Strange hole on my addon

[Serial Killer]

I've started to make my first weapon with oxygen, and this is what I made in 20 minutes.

Pretty cool, eh? ;D
Anyway, here's my problem. When I zoom in, some strange hole appears to my model.

Is there a way to fix this problem? If no, does that hole come in game?

Try selecting that face (or those faces), and reverse them.

What I think you are seeing is the rear of a single sided face, in which case it is transparent

Select the faces and press 'W'.

Not working.
I tried it many times.

Attach your p3d here if it is under 50k and I will look at it.

I sent that model to your e-mail.

...don't wanna show it to everyone...

[Planck]

Ok....check your mail.

Hey Serial Killer,

I'm not sure if Planck solved your problem or not, but I will post anyway (he probably did, Planck is a genius with this stuff)

Try selecting the hole and triangulating the faces.

Yeah, he solved it. But thanks anyway.
Thank you all!
