It should be about the diameter of a pencil. If in trouble, you can even use a pen or pencil to help you get the shape right.

For the barrel: You need to have two 15cm tubes. For the handle: You need to have seven 5cm tubes For the trigger: You need to have one 8 cm tube.

You can also glue them on straight, then cut one end of the handle diagonally, forming a slight angle. Trim down the angle with your scissors to smooth out the sides. [5] X Research source

Make sure that the tube can slide freely back and forth. This is your trigger, after all.

DO NOT close up the trigger chamber. This needs to be open to load and fire the gun. In the end, you’ll create an “outline” of sorts of the bottom of the gun. This is why using another color looks so good.

Take your scissors and cut the tube open. Then, take your rubber band and place it inside the tube. [6] X Research source Tape the tube back together. You should now have a small, squat paper roll with a rubber band running through it. This is the trigger of your gun. [7] X Research source

Fold the rectangle in half from top to bottom, creating a smaller, narrower rectangle. Then, unfold the paper. [9] X Research source Use the crease in the center of the paper as a guide. The paper is now in two halves. Fold one-half inward, so the end of the paper lines up with create. Then, fold the other half inward, so the end of the paper lines up with crease. The two ends of the paper should meet at the crease of the paper. [10] X Research source Now, fold the paper inward along the crease. You should have a long, thin strip of folded paper.

The width of the center, horizontal section should be twice the width of your long pieces. Place the strip to the right of your center line. Then fold the “arm” of the horseshoe right where it meets the thin strip in the center.

Pull the handle apart slightly. The bent down portion should have two small openings. Feed either end of the second strip through these openings. [13] X Research source Pull both ends of the second folded strip through the openings of the horseshoe. Keep pulling until the two strips are forming a wide angle of roughly 110 degrees. The two ends of the strip will form the “barrel” of the pistol. [14] X Research source

You may need to cut twice – once through the barrel and once through the opening underneath. If you do, try and stagger them a bit to make a “hammer” on your gun, or the small lever you see people pull back before shooting in movies. This little extra notch will help hold the rubber band in place. Make sure there is a deep enough notch to hook a rubber band (bullet) onto.
