I was just issued the Gen 4 Glock 17. My prior only Glock is a Glock 26 so unfortunately I cannot compare apples to apples but I find the gun well balanced and extremely easy to shoot. The weapon handles recoil nicely allowing me to quickly re-aquire my target with minimal movement after the shot breaks. I have only put approx. 250 rounds through it but it functions similar to my Glk 26 after approx. 2000 rounds and a complete spring job. I am a fan.

I tend to do a wipe down after every time I shoot. So not much, maybe 300 rounds. But I rarely detail clean my firearms, pretty much never.
