Not looking to add one, but trying to find out if some mags I have are for the Gen1 G19. I have some 10/15 mags with the gen1 style floor plate (not sure if Gen2 used the same style floor plate) and are NFML bodies. The bases, and bodies are marked Glock, but the body has no caliber marking as in 9mm on them. From what I read when Glock first came out the caliber was not marked on the mag because 9mm was the only caliber. I'm just curious in finding out more about these mags. Adding a gen1 G19 to the collection would cost around $10,000 it would appear.
