Design a gas powered compact weapon

Contest Closed
Description:
This gadget is for arm to arm combat, for military use. It is a Carbon Dioxide powered punching tool that will dispense its gas load into the recipient of the punch.
James Bond would have one of these discreetly hidden for any unexpected fight :)
The 25 gram CO2 gas canister is housed in a metal sleeve that is held in the palm of the hand, there is a hollow blade that protrudes out between the middle fingers that dispenses the gas.
The finish can be stainless steel, aluminum, cold steel, anything that looks good.
The arrow head is interchangeable.
The canister is pierced by a hollow pin on the top of the inside vessel.
If this could be 3D printed that would be great.
Wants:
Please prepare the file so that it may be taken to manufacture
Don't Wants:
It must be military focused
Software:
  1. AutoCAD

#5 ThorPunch - compact hand wepon by Vedran Starcevic
This is a rough sketch covering design and basic mechanism principle which needs to be discussed in detail (not sure how gas tank will be pierced from the side - I presumed impact force should push the tip down with enough force to pierced the tank). The tip can be easily pulled from the top as well as the tank itself. 3D pdf attached (STL or other formats on request if contest won).

#3 Gas Powered Compact Weapon Full Assembly by cetienne1116
Simple Gas Powered Compact Weapon -
Complications: 25 g is too large. See screenshot above for example. Common cartridge sizes are 12g and 90g. The photo above shows a 12g cartridge being held in the palm of my hand. This is approximately 3.75 inches in length and the 25 gram cartridge is even longer. I have designed the weapon to be used with a 12g cartridge.
Ideally the cartridge would be held horizontally in hand as this allows more space and for the hand to form a fist more fully. Unfortunately I do not believe the cartridges are designed to be pierced from the side and this could lead to further complications. For example the C02 may not discharge properly or the cartridge itself may erupt. This is why I designed my weapon with the cartridge being held vertically as is shown in the screenshot above.
Also, assuming that the cartridges are meant to be easily replaced with commercially available cartridges it was imperative to have my design pierce the cartridge from the top. There are currently no C02 cartridges on the market designed to be pierced from the side.
Finally while the system can be held in place with a fist, ideally it would be fastened to the palm somehow (rope or velcro strap, etc.)
How it works:
Piece 2 and Piece 1 of the propulsion device are attached together by a spring. As the hand forms a fist it naturally pushes piece 1 down onto piece 2. There is a pin attached to piece 1 that is hollowed (allowing the C02 to pass through it); it is this pin that pierces the cartridge as well. There is a small tube at the top of piece 1 that fits in between the middle finger and ring finger; it is here that the gas is ejected.

I think he would have followed through if he wanted it I guess it was a waste so far and be more careful for future contest from him.

That's pretty annoying (). Is there a way to report that? What's the standard procedure for this do we wait?

Are you searching for complete solution (inner trigger mechanism) or you just need casing which will be than modified to fit some existing mechanism/contraption?

Hello TP,
Hows the gas triggered? is this a one time deal by blowing all the 25 grams at once?
