I recently stumbled onto a Glock 21 in a trade with a friend. It came with some hi-cap mags so I checked the serial number through Glockmeister to see when it was manufactured. It was made in mid 1991.
So my question is:
I've heard a lot of discussion of 2nd gen Glocks vs. 3rd gen Glocks and I'm somewhat familiar with the discussion. But I'm not sure about my 21. Since it was made around the same time that the 21 entered the market does that make this a 1st gen Glock (if there is such a thing)? And if so is there anything special, different, needs to be changed/upgraded about it?
