I think that there is a possibility of damaging the spear gun rubber, as they are designed to be stretched while underwater. Leaving the gun loaded while dry would likely reduce the rubber's lifespan.
Another problem you will face is the problem of water refraction - hitting a fish in the water, that you are looking at from above the water, is very difficult due to refraction (bending of light by the surface of the water). You would not have this problem if aiming at a fish, while you are also underwater.
If you are interested, Snell's Law describes the relationship between the angles of incidence (what you see) and refraction (the true position of the fish).
