A edit of a revolver stl I found that I changed to look like the revolver from sparkle's trailer. Its not perfect, but I like it. https://www.thingiverse.com/thing:6418828 This is a remix of this file from thingverse. Mostly edited the front end and smothed the grip out. You will need to size it to what you want. 250 should be a good ball park scale.
