I would find every shred of evidence backing your statement of those firearms firing out of battery. Then compile that and have an attorney on standby.
You will likely never hear from Browning or FN again.
Of course, they will just blame it on the ammo manufacture and the ammo manufacture will blame in on the weapon manufacture, then they will both blame you for shooting an improperly maintained weapon.
Good luck and I hope you heal fast and 100 percent.
