If that's it in the pictures.
A three pin Gen 1...No.
The only Gen 1 production guns are G17 & G18. A few dozen prototypes G19s were supposedly made for the ATF.

You are correct that it is not a Gen 1 Glock. The Glock 21 did not come out until 1990 which was two years after the Gen 2 Glocks (9mm) came out (1988). Essentially, it is a 1st Generation Glock 21 since it is from the first series production design of the Glock 21. The Glock 20 (10mm) and the Glock 22 (.40S&W) came out at the same time.
