part one: airsoft stores are FEW and FAR BETWEEN.
Very tricky to find anymore. If you want to buy a gun it will be online.
part two: good news though! since airsoft is a tightly knit community, you can talk to atleast 20 people who've order from the same place (like buyairsoft or mach1 or whichever) so its not hard to find a trusted retailer. Get age verified and you will see ASC retailers who are COMPLETELY trusted and you can even read feedback left from previous users who purchased from there.
Basically, if you are not going to order anything online then go with basketball, hockey, or snowboarding
