[Need help choosing my fist gun!]

Not a CQC but not a long range rifle either, something in between thats's versatile eg folding stock or adjustable stock.

 

Also there's no where I can really go to handle them and see what they are like.

[Need help choosing my fist gun!]

The title says it all, I need need help choosing my first gun. There are so many different options and as I don't know all that much it's hard to choose. I have around £400 to spend. Thanks in advance for any help that's given.

 

EDIT: Needs to be able to be made two-tone, a good amount of rail space would be great.
