Which is better, shooting a bullet from camera or from the gun itself?

Hi, I was wondering if it would be a better idea to instantiate a bullet projectile from the camera in the forward direction of the player, directly to the dynamic crosshair, or if it would be better to instantiate it from the gun itself. I prefer to launch it from the camera but, will this give me any problems/difficulties in the long run, like later on? Thanks [Edit] I also have a muzzle flash/firing animation so it does look convincing. The bullet cant be seen either (bullets don't get seen anyways.)
