So, I have a DN prefix Glock 19. I bought it used probably in 1990 or 1991, thereabouts. It has little collector value, I'm sure, since I had the grip reshaped and I also refinished the slide myself with a bake-on finish, plus I still shoot the thing regularly. Still, I am curious as to how early my 19 is. My serial number is under 500 so I was wondering how relatively low the number is - which means I need an idea of how many DNs there are. Anyone know? Thanks. MarkG Wanna kill these ads? We can help!
