As seen in my first forum topic: https://www.instructables.com/community/DarkOwlKnex-Project-Update-One/
The DOT pistol is a pistol I built fairly recently, and have made two of since it's awesome. I'm sorry I couldn't give better instructions as it was done somewhat lazily, but it's still buildable. I'm sure there may be quite a bit of questions, so ask away, and I might upload better instructions sometime.
The DOT Pistol Features:
Very good range (I haven't tested it, but it goes considerably far with one rubber band).
Comfortable Handle (But not as comfortable as the D2OP's in my opinion).
Removable hatch DOT system
Hand modeling credit goes to my friend. HE SHALL REMAIN ANONYMOUS!!! :3
Step 1: The Handle
Step One: Make the handle; just do it.
Step 2: The Barrel
Step Two: This is where I got lazy. There was no way I was going to dismantle the thing, so I just took pictures of it at different angles. If you have any questions, just ask, and I might upload a picture on what you're confused about and add it to the instructable. The last two pictures are the pistol in my forum topic because of laziness. Just like I'm too lazy to explain how using the other pistol was a shortcut.
