Can't say what the problem is...if it is a NIB gun maybe it needs cleaning around the striker...to make sure no grease or dirt is keeping the striker from moving forward.
Break in is usually around 500 rds so don't give up yet...there are some knowledgeable guys on this forum and I am sure that they can give you more advice...
Worst scenario is that you call WaltherAmerica…they can give you some advice. I will say this that the P99 is too good of a gun for it to be anything major that cannot be worked out with a little help. I think you will find that the P99 is just as good as your 228, no kidding.
