Milk snake identification

[Spidermolt]

I just picked this fella up today at a local pet store and was wondering if anybody here could identify the exact species of milk snake?

Guessing sinaloan.

Lampropeltis polyzona, abnorma, and annulata are all similar, 90% sure this is polyzona (sinaloan milksnake) based on the snout tip.
