Hello, I hate to bring this up, but i'm not clear on all the rules yet. My father has a Ruger p89 9mm he bought back in the early 90's, and I want to get him a couple more mags for his B-day coming up. I found a couple mags for purchase but not sure how to aquire them legally due to the capacity, and no dates on the mags. I just got my LTC unresricted. Thanx
