Can you help me design a gun for Earth Ponies?

[Stallionslaughter 394]

I have been trying to design guns that Earth Ponies can use, but I'm having a difficult time creating something that is both practical and accurate. I've finally nailed down a design of how it may work, but I can't seem to get around making it less fragile looking.

 

I'm no engineer, but the idea I seem to have down just looks delicate.

 

The distance between the mouth and hoof is too great, so I think the mouth driven trigger is out. Also, I think that a hoof stabilized handle would disable running to far too great a degree. Without going to Predator shoulder mounted route, can anypony help me out? 

 

Attached is my initial design. Here are the notes:

 

1. Cylinder hinges open to allow bullets to be loaded.

 

2. Small step plate is depressed to release cylinder.

 

3. Hammer is pressed down with hoof or top teeth and locked back for single-action revolvers. For double-action, the trigger mechanism pulls back hammer automatically.

 

4. Trigger rod is pushed forward by the user biting down on the trigger plates.

 

5. Trigger rod rotates trigger mechanism, releases the hammer, and ignites a center fire cartridge.

 

6. The weapon is stablized by a hoof cuff around the front of the hoof.

 

7. A rubber lined cuff fits between the ankle and coronary band to prevent the weapon from being unintentionally dropped. Pressing down on the bottom of the hoof cuff brings the coronary band cuff upwards and provides the user's grip to the weapon.

 

8. Trigger plates are bitten to depress the trigger rod which rotates the trigger.
