I found it at ShareCG when I was browsing there. So I posted the link.  I'm not going to do double duty and search the free stuff here before posting a link.

Also, the gun doesn't show up in the search here under "gun", you have to enter "Baby" or "Dragon" or "Barrel".

So unless people knew to search for those words, or spent hours browsing the uploads, they wouldn't have found it here.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
