You need to rig this up to an actuator. There are lots of things you could do with that.

You could detect when a machine pistol is getting uncontrollable muzzle rise, then stop it until the trigger is released and reapplied.

You could hold off firing until the gun is stable. When the trigger is pulled, look for smooth movement. (no angular acceleration, and the regular acceleration has a stable magnitude equal to gravitational acceleration) The motion for leading a duck is fine, but the motion of stumbling and getting snagged on bushes is not.

You could disable the gun if acceleration goes to zero, for example by being dropped. After half a second of stable gravitational acceleration, reenable the gun.

Hi! I see a lot of "you could" in your reply, but I'd like to point out that I released this as an open-source DIY project so that anyone could do whatever tests they wanted. I encourage you to build your own -- I'd love to see what you can make and learn with it!

It's just a few free ideas. I'm thinking you or anybody else could have fun and/or create a profitable business.

Fair enough! I don't have the budget for a machine pistol, but maybe someone who does can try that idea out.

The other two ideas apply to typical guns.
