IMO unless a dog has an unstable temperament or is extremely ill dog's just don't snap. There are always signs
Congrats on your new addition.
I think it would be in your best interest to start doing research on both breeds so you learn what is and isn't proper temperament for them. Also early socialization obedience training as well as really learning to know your dog and his body language and comfort zones is important. This all will help make you a more responsible owner and make for a better pet.
Good luck with your new pup! Post some pictures

I don't see why you should have a problem with that mix if you train him right. You cant let him win over you, and you should seek several obediance classes. I love pits, so you will never hear me say something bad. I would love to have one, but my insurance wont cover anything.
Congrates with you new baby, and may you have many happy years together
