How accurate is a flare gun converted to fire live ammunition?

A converted flare gun, like the HK P2A1, is not a precision weapon due to its lack of sights and inconsistent point of impact. It is best suited as a close-range 'get off me' weapon where accuracy is less critical than immediate stopping power.

What are the legal implications of using a flare gun with live ammunition for self-defense?
