Introduction: Double-barrel Magazine Pistol W/ 'clip-on Mag'

About: K'nex guns, TF2, and Valve games are what I like to build/play.

I like this new weapon.No exotic or modded pieces
It's a shotgun
you don't have to load in bullets every time you want to use it
(unless you didn't build the magazine version)

Very little space in-between trigger mech and ammo.
Not a very gun-like magazine
Cannot chose whether to fire one shot at a time, both shots are fired.

Changes from initial design:
Added removable mag which is also kind of like an extension barrel. I would call it a 'clip-on' mag.
Fires different ammo.
