A Glock 19 Mystery Generation

[Masnor]

I have a G19 with finger grooves (suggesting Gen 1 or 2) but only one pin above the trigger and a pin in the grip (suggesting a later Gen, but I think it is too old for that).
The SN is DRR042. I haven't been able to find it on different references from OKShooters (or elsewhere) .
The first letter D isn't in the date list and the sn returns no info on the sn lookup link.

Any thoughts?

Gen 3

Early Gen 3, April/May of 2000. The third pin in the 19 appeared a little bit later.

Rail, and finger grooves indicate Gen 3.

Is there a date code on the barrel hood? Do all of the serial numbers match?

Yes, a Gen 3 two pin pistol.
