I just acquired a "new", unfired Glock 19 Gen 2 that I plan on using as my ccw. Even though the gun is unfired, it still is 21 years old. Should I treat it as a new gun or replace all the springs for good measure -- since they are so old? Also, based on the pictures I have seen, it came with 2 pre-ban mags -- square notch, full-metal lined, drop free. Would anyone know the residents of which States it is legal for me to sell to? I would rather sell to those who can only have pre-ban mags than keep them myself, not living in a ban state. Any help is appreciated. Thanks in advance.
