"The Bar Gun"

Here's what I have been working on for the past 4 weeks. It's not much, but i will soon finish hopefully.

Gun's History:
1.I made the first prototype of the gun. The results shocked me as they were very poor.
2.I drew a drawing on how the gun will function and what kind of body will It take to make It function.
3.The body I had drawn became strong and sturdy, but I did not add anything just yet.
4.Everything was In tact, now all I need Is a good handle and trigger.
