The Leapers UTG 547 Law Enforcement Tactical Vest has 3 AR15 magazine pouches that will accommodate a 40 round magazine. However, unless you wanted to use the AR15 pouches for your 30 round 9mm magazines, you would not be able to fit them in this vest.
Yes, the pouches can fit those magazines.
It should be able to zip up just fine it but will always be best to verify that information with Leapers directly to make sure you don't have to do any returns.
