hows it fire?

The action seems to be unmodified, I don't doubt it would cycle and fire fine.

The problem I see is the placement of the foregrip. This setup of stock + foregrip would be painfully awkward to fire, especially since the foregrip is so close to the trigger group.

I would recommend doing away with the foregrip entirely, or moving it to the very front of the frame for better handling and more space for the second hand to fit.

I'm just saying it remined me of Leon S Kenndy's gun so it made her look like shes a burst gun

I could see that it looking like Leon's handgun but it's actually based on a gun from CoD WWII

oh I'm not that versed in cod, the players being a reason

The firegrip is actually set in storage mode and slides forward when in use and yes the action is unchanged so it's good for a marksman rather then to just spray and pray

There's no mechanism by which a foregrip like that can slide forward in use and still perform it's function. As for being used by a marksman... No. A 1911 doesn't have near the sight radius to manage marksman level accuracy. Not to mention the fact that it's barrel length, even when extended, doesn't provide the pressure needed for even mid distance engagement.
