Um, nothing would happen because the plastic isn't hard enough to make the bullet go bang in the first place. If you had metal components in it than the bullet would bang and the tip of the gun would suffer sever damage (melting, cracks, fractures, etc..) The barrel of the gun would also be pretty messed up. If anything of the gun is left undamaged (for the most part), it would be the handle sense that is the furthest away from the blast "zone" If you do shoot it and are holding the gun (you don't have a stand, like they use on TV so nobody gets hurt) than you would be most likely hurt.
More than likely it wouldn't work. The firing pin would have to be strong enough to dent the back of the brass shell, which causes the gunpowder to ignite producing an explosion that expels the round out the end of the barrel. The barrel would have to be strong enough to direct the round forward. Either way, nothing good can happen out of that.

I read an interesting thing about something like this. With the advent of 3D printers some guy (who seemed a little...eccentric) wanted to create gun patterns so anyone with a 3D printer could print themselves a gun (that would be made of the plastic resin the printers use).
I think the journalist writing the article found out that (without additional components) any such gun would be unlikely to be able to fire more than one shot before breaking.
It would depend on how strong the plastic is and what type of bullet is used. Weak plastic would probably shatter unless the bullet has less powder than normal. Not sure if there is a plastic that would work. There was a movie with John Malkavich where he made a gun out of some type of plastic and it used 22 cal bullets. Of course that's a movie. Don't know about real life.

Provided everything was made of a strong enough material for the firing mechanism to perform at all (a stretch, but to go along with the question) you would have poor accuracy and a one-time use gun. A pistol would be more tricky and less likely to design functionally than a rifle.
Recently the media has made a big deal of this issue. What people are overlooking is that this technology has been around for a number of years and on the non-consumer market, better prototypes exist, moving more towards metal printing.
In short, if you shot a pistol made with a hobbyist's plastic printer it could melt in your hand, and could be hazardous to your health. If you were very lucky and it was really weak plastic with very little force, nothing might happen at all. You would have to get up to a higher level of technology that hasn't been completely developed before that would work very well.
If the entire gun were made of plastic? Not just the reciever (handle)? If you can somehow make a spring out of plastic strong enough to get the hammer/striker to fall with enough force on the primer to set it off, the thing would no doubt explode.
The bullet would be in no way accurate, and the gun could be used only once because it would either melt or explode, definetly hurting your hand and any other uncovered part of your body. My friend almost died because he poured a shotgun shell's innards into a plastic Sprite bottle and it exploded and shards of plastic and beads went everywhere. Don't try anything like that
