Can the NES ma**h***s settle this once and for all? Friend's little brother just got his shiny new LTC-A "LARGE capacity" and wants to know if he can start carrying the holy grail pistol in MA - a Glock 19 Gen 5 but with preban mags so he gets to have 15+1 like the thin blue line boys do. Somehow this kid got his hands on a preban square notch low number mag in pristine condition and a couple U notches as well. Here's the twist to the uncertainty - do we need to prove we "owned" the prebans since before 1994 or does it just have to be in MA before then? That would be a problem considering this kid is way younger than the mag. How could he have owned the preban if he was born in 1999? Inb4 'your second amendment says you get to do anything you want with guns'. Thanks yall
