I had my Duty gun Laser inscribed with my name, badge number and service dates. I know it doesn't mean anything now, except to my family, but, in a hundred years, would it gain value? Or lose value. I carried the Gen II for 24 years. I did carry a Gen 1, but it was replaced with the Gen II, after a shooting that I was involved in. The Gen 1 doesn't come back to any specific Ofc., but the Gen II should. MPDC was the first agency, in the U.S.A. to be issued Glocks, if that matters. And the Gen 1 has "MPDC" stamped on the slide.
