I have a question concerning Glocks. I often see reference to 1st generation Glock, 2nd generation Glock, etc. I know this refers mostly to the date of manufacture and each generation of Glocks would have certain characteristics or features. Does anyone have more details as to what constitutes each generation? I have several Glocks and each was manufactured about 5 years apart as best I can tell. While all are very similar, you can definately tell the difference. My first handgun purchase was in 1998. I picked up a G22 LEO trade-in that was mfg in 1995 (per Glockmeister.com). It has a straight grip (no finger grooves). Still shoots as good as any of my newer guns. I have a G26 which I purchased new around 2001 (Glockmeister said it was too new to date) and a G30 I purchased new this year. I really like the cosmetic and ergonomic changes which have been made over the years, even though they are ever so slight.
