Weapon Projectile question

So i made a model(hovercraft) and added 3 pistols and wanted to know how to do like the attack animation that there comes out fire out of the three pistols

There are three ways of doing this, with particles, billboarded planes or both which is recommended. Add a plane that is billboarded with an addictive glow texture on it to the point of fire. Then make a particle emiter at the point that fires and attach it to a bone then animate it to point forwards. I know this can be a bit tricky but fiddle around with it and you'll get it. Use the Clouds8x8Fire texture or something for the animated fire. There's more info on particle emiters in the manual that comes with the art tools.
