You can flip cock without breaking your fingers. Stop repeating urban legends thinking you're some kind of expert. You could certainly hurt yourself doing it (and damage the weapon), but broken bones would be an extreme case, but that's a moot point anyway, because with practice and training you can do it safely.

And firing a 12 gauge with one hand won't normally break your wrist either, it would just hurt a lot. But again, you could probably minimise that with training.
