Well, I finally got rid of my Taurus 24/7 OSS as was able to fund well over half the purchase of my Gen 4 G17. I shot 100 rounds through the Gen4 without any problems at all. I did not shoot it side by side with my 2nd gen G17, so I can't tell much difference in the recoil. The only strange thing I noticed about the gun is that sometimes when disassembling it, the recoil rod falls free of the slide/barrel. It happened once when I was at the range, and again after I got home. I'm still very fond of my 2nd gen gun for sentimental reasons, but I think the 4th gen will be more shooter friendly for me.
