Here’s another of my seemingly unavoidable weaponry ideas.
One problem when firing a handgun is the twisting that happens during recoil. Watch a high-speed film of this and it’s amazing that people don’t break their wrists. Getting the next shot anywhere near on target is therefore going to be difficult.
In order to help alleviate this difficulty, I suggest creating a revolver with two barrels. These admit bullets simultaneously from diametrically-opposite chambers and fire together using a unified hammer system.
The propellant in each bullet could be halved to lessen the overall recoil. The barrels are rifled in opposite directions so that the torques created cancel each other out and the wrist twisting is greatly reduced.
No need to restrict the cylinder to only six bullets of course. More bullets = lower recoil movement.
