Aside from the fact that I don't think anyone has actually been able to make one, what specifically would you like to know?

I can't really tell you much. (My own search found nothing but video game weapons.)

There are two main problems that I know of. First is the production of the plasma. A plasma is a gas-like substance in which the material has been stripped of its electrons. In fact most people might think of a plasma as a kind of "electron gas." It is very hot and very tenuous. That is to say it has almost no density. It takes a lot of energy to create a plasma of any decent size so any plasma gun that might be built is going to have to be rather large. (I should point out that it is relatively easy to make a small amount of plasma. Neon lights, if I recall correctly, operate by passing an electric current through the Neon, creating a plasma.)

The second problem with a plasma gun is, again, that the plasma has a very small density and it is very hot. These conditions are easy enough to meet by containing the plasma, say in a tube, but if you let it out into the air it will dissipate, cool down, and then you have no plasma at all. So a plasma gun is going to have a very short range.
