What country
You'll need to be more specific - there are 5 pistol models that use .40 S&W rounds. They are: -Glock 22 -Glock 23 -Glock 24 -Glock 27 -Glock 35
Every generation higher is better than its predecessor, so the 3rd generation is better than the second generation, but not by much. The 3rd generation only has a faster downloading or prosessing system then the 2nd generation but you can upgrade that for free or for about 5 dollars.
used is about 65- 70 dollars!
around $150
