TFA base issue regarding c_smg1.mdl

[condes]

bassically, when i place "c_smg1" in shared.lua the weapon starts to dissapear whenever i'm pressing fire, when it's out of ammo, just for a second,
i compared the lua file to other sweps that use "c_pistol" and "c_crossbow" and there seems to be no big difference between them, but the they don't have that problem.
has anybody faced with that type of thing? have idea of what might be causing this?
here's a youtube link just to make clearer what i'm talking about [url]https://www.youtube.com/watch?v=8WkmfFN7MR8[/url]

and the code:

SWEP.Gun = ("tfa_hl2_mp7") -- must be the name of your swep
