I was throwing random k'nex pieces together when I made something that looked kind of like a body for a gun, and then I had a pistol. Now about the pro's and con's...
Not good for long range shots (Shoot 25-35 ft.)
Step 1: The Body
This is the hardest step, but it's pretty easy. Just follow pics and READ ALL IMAGE NOTES or your gun won't work.
Step 2: Trigger
This piece is necessary to the gun. Once again, READ ALL IMAGE NOTES!
Step 3: Panels
You're almost done. Just add on these panles and read all the image notes.
