I've been trying to find some pre-ban 15 round flush fit mags for my P229 9mm and haven't been able to find any yet, so I have a plan. Is it legal for me to:
1) Buy a preban 13 round mag online
2) Then buy a postban 15 round mag in NH and bring the preban 13 round mag with me (drive to NH and buy it and don't bring it back into MA)
3) WHILE STILL IN NH take apart both mags and put the follower and possibly base plate if its needed from the 15 rounder into the 13 rounder.
4) Throw away the left over pieces from the 15 rounder before coming back to MA with my newly modified mag.
I'm not creating a new high cap feeding device since the one I was modifying was already high cap
I'm not bringing postban high cap mags into this state, just one piece from one
Could I just buy replacement parts (follower and base plate only) for a post ban 15 rounder and put them in preban 13 rounder?
Thanks
EDIT: This isn't the same as http://www.northeastshooters.com/vbulletin/threads/104987-Pre-ban-mags-can-you-update-the-internals because I'm asking about a preban to postban swap.
