I am a reserve deputy for my local sheriff dept. We are switching from the Glock 22 to the Glock 17. As a reserve we have to buy our weapon. I can get a Gen 4 Glock 17 with night sights for 409 bucks through the dept. Or I can go out and find a Gen 3 on my own. Which way would you go? I have had no issues with my 22 or my 19, and I do not mind spending more if needed on a Gen 3. Thanks Chris
