Except that isn't really true. Ethics laws in MA prohibit "giving" guns/mags or anything else to public officials upon retirement (that is the qualifier in the law), so it is no-go.I noticed an interesting carve out for retired cops in the bottom of that. Very interesting and sadly very typical.
Many years ago it was common in MA for PDs/MSP to gift their service gun to a retiree . . . not anymore unless people want to go to jail.
